Ruling is further evidence of NCAA tightening stranglehold on college athletes

If “Tattoogate” has truly resulted in any inking, it’s colored Ohio State’s student-athletes black and blue — by the NCAA. The NCAA’s ruling has put OSU’s hopes for a strong run next season into jeopardy. It not only forces five impact players to sit out the first five games of the season — including non-conference games at home against Colorado and on the road against Miami (Fla.) — but also has seemingly put the early nails in the coffin for  quarterback Terrelle Pryor’s Heisman campaign next season. In fact, the ruling suddenly has diminished Pryor’s prospects for even returning to the gridiron his senior season. Despite all that, the bigger issue involved here is the NCAA hammering its soulless, iron fist. In what’s now being called “Tattoogate,” five OSU football players — Pryor, Daniel “Boom” Herron, Mike Adams, DeVier Posey and Solomon Thomas — must sit the first five games of the 2010–11 football season and repay between $1,000 and $2,500 to charity. All because they sold their personal belongings and traded autographs for tattoos. None of these players was taking payouts from agents, receiving free Hummers or partying on private yachts with rappers. Instead, Pryor sold his things to help out his mother, Pryor’s high school coach Ray Reitz told ESPN. The reality of life is that sometimes people need to sell their things to get by, even if they’re cherished. We don’t know what sentimental value these players placed on the rings, awards and jerseys they sold, but if these players truly were in financial need, is it really appropriate for the NCAA to punish them so harshly? Few people actually want to sell their wedding ring, but sometimes it’s necessary to help make ends meet. Buckeye fans might feel a little stung that Pryor sold a Big Ten championship ring and his Gold Pants, but if Pryor truly was trying to help out his family, can we really be that upset with him? And is trading a tattoo for an autograph really so bad? It’s not like these players were trading tattoos for an all-expense-paid vacation to a party at the Playboy Mansion. Erik Kuselias of ESPN’s “Mike & Mike in the Morning” makes a good point: These athletes can receive hundreds of dollars in free merchandise for playing in the Beef ‘O’ Brady’s Bowl, but trading an autograph for a tattoo is worthy of a five-game suspension? Great logic, NCAA. Great logic. Let’s not forget the NCAA’s inconsistency, either. Earlier this year, the NCAA ruled that Auburn quarterback Cam Newton was eligible to play, despite reports that his father was shopping him around to universities for six-figure payouts. However, according to the NCAA, an investigation is still ongoing. The NCAA also took several years to reach a verdict in the Reggie Bush case at USC, where Bush received $300,000 in illegal benefits. Bush played at USC from 2003-05, and it wasn’t until June 2010 that the NCAA placed the program on four years probation, forced them to vacate victories and stripped them of scholarships. Being angry with these players for making a mistake might not be the best way to direct our aggression. Instead, we should be more upset with the NCAA for its ridiculous stranglehold on the lives of student-athletes. We should also push the OSU athletic department to educate student-athletes more thoroughly on rules violations. Athletic director Gene Smith even admitted Thursday in a statement that OSU didn’t do a sufficient job educating its student-athletes about these types of violations. And remember that report in The Lantern saying that OSU has an allocation of about $500,000 set aside to help student-athletes in financial need? Perhaps OSU should do a better job of letting these players know they aren’t going to be totally hung out to dry if their wallets are running on empty. It’s not known for sure what the intentions of the players were yet or what the money was spent on, but if the players truly had only good intentions, the NCAA’s ruling is just another case of the NCAA exploiting its embarrassing and illogical stranglehold on each and every move student-athletes make. read more

Loris Karius I was never told to leave by Liverpool

first_imgLoris Karius has denied he was ever told by Liverpool to leave this summerThe German goalkeeper ended a two-year stay at Anfield this summer for a move to Turkish giants Besiktas on loan after Liverpool signed Alisson Becker from AS Roma.The decision to sign the Brazil international came after Karius’ mistakes in Liverpool’s 3-1 defeat to Real Madrid in May’s Champions League final.“It was a super season with a very unfortunate end, but you must get over it,” Karius told Bild.“I knew that I must get up again and not hide and only concern myself with the past. It was a super team performance to just reach the final. Nobody can take that away from me. Not many German keepers can say they’ve played in a Champions League final.“A lot of things came together that day, and even though nobody wants to hear about it, you will never know how much my mistakes were connected to the injury which was diagnosed later. That’s no excuse — just an explanation.”Roberto Firmino, LiverpoolVirgil van Dijk praises Roberto Firmino after Liverpool’s win Andrew Smyth – September 14, 2019 Virgil van Dijk hailed team-mate Roberto Firmino after coming off the bench to inspire Liverpool to a 3-1 comeback win against Newcastle United.A possible explanation for Karius’ mistakes at Kiev could come through a concussion he suffered after Sergio Ramos’ elbow hit him.The Real Madrid captain never apologised to Karius afterwards and the German admitted he watched the footage several times for the next two weeks.“For one [or] two weeks, it was on my mind every day,” he said.“You sometimes don’t understand how a situation like that can happen,” he said. “I wanted to understand it better and that’s why I watched everything again that night and the following day.”Liverpool boss Jurgen Klopp explained his reasons for parting with Karius were nothing personal.last_img read more

Solskjaer sure he would agree to stay as Man United boss

first_imgOle Gunnar Solskjaer is “sure” he would stay on as Manchester United’s permanent manager if they asked him to at the end of the seasonThe Norwegian has taken charge of United for the remainder of their 2018/19 campaign following Jose Mourinho’s sacking this month.Victories over former club Cardiff City and Huddersfield Town have since followed ahead of United’s Premier League game against Bournemouth today.Despite Solskjaer’s actual employers Molde FK insisting they have only “lent” him, the ex-United striker wouldn’t say no to sticking around at Old Trafford.“My job is for the next five months, because I’m going to leave them to someone else when they come in,” Solskjaer told Sky Sports.“That’s the plan and that’s what my job is at the moment, it runs out at the end of May – actually the end of June but we don’t play many games in June – so my job is to affect the players on what it is all about at Manchester United.“You’re always ambitious of course, but as I’ve told Ed [Woodward, United chief executive] and the owners, I’m here to do as well as I can and, if in May you decide someone else will be coming in, then fantastic, and if you decide it’s me, I’m sure we will agree.”Harry Maguire, Manchester UnitedLiverpool legend Nicol slams Harry Maguire’s Man United form Andrew Smyth – September 14, 2019 Steve Nicol believes Harry Maguire has made some “horrendous mistakes” recently, and has failed to find his best form since joining Manchester United.Solskjaer scored 127 goals in 364 appearances for United over 11 years and has focused mostly on attacking play during his managerial career.But, with United having already conceded 31 league goals compared to leaders Liverpool’s eight, Solskjaer is aware of the importance of a solid defence.“I’ve been here for 15 years before and of course my football philosophy is driven by what I experienced here,” he said.“We do go and attack teams, try to dominate games and go into every game believing that we’re going to win, although we respect the opposition of course.“It’s not like we used to win 5-4 every time with the boss [Alex Ferguson]. When we had Jaap [Stam], Ronny [Johnsen], Rio [Ferdinand] and Vida [Nemanja Vidic] at the back, you knew that we could keep a clean sheet, so there is a fine balance there.“And I love seeing players express themselves. It probably comes down to that I experienced more in my football career than I ever believed, so I want other players to have the same feeling when they’ve finished their careers – that means we need to win.”last_img read more

Tyndall AFB Update Senator Pledges to Restore Base Air Force Leadership Assesses

first_img Dan Cohen AUTHOR Florida Sen. Bill Nelson (D) on Monday vowed that Tyndall AFB would reopen, after the installation sustained catastrophic damage when Hurricane Michael, a Category 4 storm, made landfall last week on the Florida Panhandle just miles away. Nelson countered speculation that Tyndall would not be restored to its previous role but, instead, realigned as was the case for South Florida’s Homestead AFB after it was decimated by Hurricane Andrew in 1992. “I think that fear is unfounded,” Nelson said, reported the Orlando Sentinel. “As a senior member of the Senate Armed Services Committee, I can say that Tyndall will be rebuilt, and it will be an example of a modern U.S. Air Force base. That is because it is critically located right next to one of our greatest national assets, the Air Force Eastern Gulf Test and Training Range, which is the largest testing and training range for the United States military in the world.” … On Sunday Air Force Secretary Heather Wilson, Chief of Staff Gen. David Goldfein and Chief Master Sgt. of the Air Force Kaleth Wright surveyed the damage at Tyndall. In response to a question as to whether the installation might be a total loss, Wilson said the situation could improve in as little as two weeks, reported Stars and Stripes. After the initial shock wears off, “I think people will really start to see the future and not just focus on the present,” she said. As of Sunday, the base still had no power or water. … The Air Force Northern Command Air Operations Center, which is responsible for air security and defense for the continental United States, is being shifted from Tyndall to Langley AFB, Va., reports Stars and Stripes. The air operations center suffered only minor damage from Michael and now is hosting the 325th Fighter Wing and various recovery teams. The First Air Force will consolidate its Air Forces Northern and North American Aerospace Defense Command missions at Langley, where they are likely to remain through the end of the year.Air Force photo by Tech.

Exclusive Nithin Renji Panicker talks about new Suresh Gopi film artistic freedom

first_imgCould you tell us more about your new movie which features Suresh Gopi and Lal in the lead role? This movie is set in the backdrop of a high-range area in Kerala. It is basically an action drama, and it will have elements of family emotions and suspense. I am hoping to make an entertainer which will cater to a majority of the audience.Suresh Gopi and Lal have delivered some memorable hits that include Thenkashipattanan and Kaliyattam. Can we expect the same to happen with your new movie? I am not sure if you can expect the same. But both of them have strong roles to play in the movie, and you will get to see their combination sequences. It is going to be very interesting. Could you unveil more details regarding the cast and crew of this upcoming movie?Casting is still on the go. It will have popular faces from the current bunch of actors. There is a prominent female lead, and it will be enacted by a young actress. The cinematography of this movie is handled by national award-winning cameraman Nikhil S Praveen. Art is by Dileep Nath. Mansoor Muthutty is in charge of the editing, and the costume department will be handled by Nizar. The music of this movie will be composed by Ranjin Raj of Joseph fame. A few months back, Suresh Gopi himself confirmed that he will be reprising the role of Aanakkattil Chackochi in a film titled ‘Lelam 2’. Later, a casting call post appeared in Renji Panicker’s Facebook page inviting new faces for this film. What is the status of this magnum opus project? Lelam 2 will hopefully take off next year..not sure..if it does it’s going to be a huge project. Fingers crossed. Your father Renji Panicker is a legendary Mollywood scriptwriter known for his firebrand dialogues. Could you tell us more about your father’s influence while you write scripts for your movies? I am very influenced by my father’s scripts and dialogues. The way in which he molds and shapes the characters in his movies also inspire me a lot. His scripts are very detailed and you get a clear picture about what to shoot, how to act and the total mood of the scenes at a single reading of each scene.I am very influenced by his scripts. Even though I can’t match it on any level, I am eagerly waiting for him to write something for me. Nithin Renji Panicker, the young filmmaker who made his memorable debut in Mollywood with Mammootty’s ‘Kasaba’ is all set to storm the theatres again with his upcoming untitled venture.The film will feature Suresh Gopi and Lal in lead roles. Son of legendary Mollywood scriptwriter-director Renji Panicker, Nithin aims to affirm his unique spot in the industry with his impeccable filmmaking skills and uncompromising cinematic language.In a recent interaction with International Business Times, India, Nithin Renji Panicker opened up about his upcoming movie, the influence of his dad while writing scripts, and the prerogative of a director to enjoy seamless creative freedom.After your debut venture ‘Kasaba’, it took almost three years to finalize your next project. What caused this hiatus?Three years is a long gap for anybody after their debut. I was supposed to do a sequel to Lelam titled ‘Lelam 2’in 2017. But unfortunately, the project did not take off due to various reasons.My father, who was supposed to write the script of the movie, also had acting commitments. In the meantime, I planned something else with Suresh Gopi but that project had to be shelved as well. Thus, I decided to write something of my own and finally landed this project. Apart from being a scriptwriter, Renji Panicker has proved his versatility in acting and your brother Nikhil is debuting as an actor with the movie ‘Kalamandalam Hyder Ali’. Do you have any plans to pursue a career in acting? I recently did a small role in Anoop Menon’s directorial debut KING FISH. I had four small sequences. It was a good experience. Maybe because I have known him from before and we have a friendly relationship. Let us see.After the release of Kasaba, many people, including a leading Mollywood actress, lashed out against you and lead actor Mammootty for an alleged anti-feministic sequence in the movie. Even though the controversy is more than three years old, you have not reacted to it publicly. Could you brief us how these controversies are affecting the creative freedom of a filmmaker? I haven’t responded to those alligations even then. They have their opinions. I am not all bothered because I don’t see anti-feministic elements in Kasaba. Controversies don’t affect my creative freedom. If I think I shouldn’t write something, I wont..if I feel I should write something, I will do that without any hesitations. center_img RelatedEXCLUSIVE: Murali Gopy talks about Lucifer sequel, artistic freedom and Illuminati linkExclusive: Nikhil Renji Panicker talks about Kalamandalam Hyder Ali, influence of dad and futureOdiyan director Shrikumar Menon defends Mammootty, says actor is ‘cornered and deeply hurt’last_img read more

Over 300 adolescents involved in 99 Dhaka murders

first_img.Over 300 adolescents have been involved in 99 murder incidents over the past 16 years, according to records of different courts in Dhaka.“Young children are becoming more and more involved in murder in Dhaka,” said state prosecutor Shahabuddin Miah who has been conducting cases for over three years at the Dhaka juvenile court.Speaking to Prothom Alo, he said they are killed in clashes between seniors and juniors. Adolescents are involved in these incidents, Shahabuddin Miah added. Prothom Alo investigations reveal that over the past one and a half years, at least 120 adolescents have been involved in 13 murders, and cases have been filed in their names. Of them, 27 have been arrested and detained at the juvenile development centre in Gazipur.Previously juvenile crimes were tried at the Dhaka juvenile court. From 19 January this year, such cases are being tried at the Women and Children Repression Prevention Tribunal. Till 31 December 2018, there were 1,381 cases under trial at the juvenile court, 86 of these being murder cases. These incidents took place over the past 15 years.Police have even issued charge sheets against over 150 young boys.The children arrested in such crimes are sent to the juvenile development centre in Tongi, Gazipur. Supervisor of the centre, Jahangir Hossain Chowdhury, told Prothom Alo, till 30 April this year, there were 724 young boys at the centre, who had been involved in crimes related to drugs, murder, assaulting women and children and such.A senior official of the juvenile development centre, on condition of anonymity, said that 277 of the 723 child inmates were accused in drug-related cases. After drugs, the most cases against these young ones were related to rape and killing.According to Prothom Alo’s findings, most of the arrested children were involved in narcotics. Records of Dhaka’s juvenile court show that police had issued charge sheets in 146 narcotic cases against the young ones. There were 68 cases against adolescents accused of theft. Then there were 61 cases against over 150 adolescents accused of rape, attempted rape and sexual abuse.The social welfare department deals with child ‘criminals’ who have been brought under the law. An official of the department, Suman Madhu, told Prothom Alo, these young ones are being involved in drugs, killing, rape, mugging and all sorts of crime. Such cases are on the rise.Why are the young ones turning to murder?Documents relating to 30 murder cases against adolescents reveal that most of the murders among these young boys are a result of clashes between juniors and seniors. Of the 30 murders, 14 were because of these conflicts. Both sides in the clashes were acquainted with each other. The young boys were also involved in clashes over rivalry related to love affairs. Six of the 30 murders were the result of such love-related rivalry.These young gangs were also involved in spreading their power in various areas of Dhaka city. Six of the 30 murders were related to these power tussles.The murder cases against adolescents indicate that the young victims of such murders are mostly between 12 and 17 years of age. And most of the killers are between 15 and 18 years of age.Shaon, a 15-year-old student of Gandaria High School in the capital city, was seriously injured during a gang fight near his school at 10:30 on Saturday night. He succumbed to his injuries and died the next day. Eight days before this incident, 15-year-old Yasin Arafat was killed in Hazaribagh of the city. Police say both Shaon and Yasin were killed as a result of conflict between seniors and juniors.Fifteen-year-old Arif would work in a factory of Old Dhaka. He was stabbed to death on 15 March this year in front of Dhaka University’s Curzon Hall. Police say six members of an adolescent criminal gang killed him. They would regularly carry out snatching and mugging in the High Court mazar area.Professor of criminal science at Dhaka University, Zia Rahman, spoke to Prothom Alo about the reasons why these young boys were getting involved in crime. He said, the relationship which the adolescents are supposed to have with society is missing. Social and family control has broken down. A large section of the adolescents are obsessed with the Internet and video games. They turn to pornography. Overall, there has been a change in the psychological mindset of adolescents. That is why they become involved in all sorts of serious crime.Senior-junior clashesEighteen-year-old Shakil was killed on 1 November 2012 in Bhatara. Police told the court that before Eid, Shakil had become involved in senior-junior clashes with fugitive criminal Sher Khan in Bhatara. He was killed in these clashes.On 12 April last year, SSC candidate Russel Rony was killed. One of the accused in the case revealed in court that Russel used to study in Khilgaon Government Quarter High School. On the day of the incident he had gone to play cricket in the local playing ground and his team won. This resulted in clashes with the defeated team and Russel was stabbed and killed in the clashes.Lawyer Faruk Ahmad has fought cases on behalf of many adolescents and has interacted with their families. He told Prothom Alo, family ties are not like before. Many parents in Dhaka cannot give their children time. Many young ones are turning to drugs. There is a strange propensity among these young boys to display their ‘heroism’.Gangs and power playShezan, a 15-year-old boy, was killed on 7 March this year next to Dhaka Medical College Hospital. A juvenile criminal gang of Chawk Bazar and Bangshal was involved in the killing. Three of the gang members were arrested. The Police Bureau of Investigation (PBI) told the court in March that there were several senior-junior groups in Suritola, Chankarpool and Malitola of Chawk Bazar and Bangshal. There was a power struggle between these groups over gaining control of the localities.Deputy commissioner of Dhaka Metropolitan Police’s Lalbagh zone, Ibrahim Khan, told Prothom Alo, gangs cannot grow in Old Dhaka in the same manner that the gang culture has grown in Uttara because Old Dhaka is too congested. However, Shaon Hossain, uncle of the killed Shezan, said there are adolescent groups in Chawk Bazar and Bangshal. They are involved in all sorts of crime in the area.Love conflictsRounak Hossain, an HSC student, was killed on 1 March last year in Old Dhaka’s judge court area. Police told the court that he was killed as a result of conflict over a love affair.About four years ago on 19 October 2014, a businessman was killed in Mirpur. Police investigations revealed that the businessman’s wife was involved in a love affair with a young boy. The boy, along with three of his associates, killed the businessman.*This report, originally published in Prothom Alo print edition, has been rewritten in English by Ayesha Kabir.last_img read more

New Blaze Erupts In Los Angeles Area

first_imgTwitter via @Gallen4presCalifornia wildfires reaching LAA dangerous new wildfire erupted in the tony Bel Air area of Los Angeles early Wednesday as firefighters battled three other destructive blazes across Southern California.Flames exploded before dawn on the steep slopes of the east side of Sepulveda Pass, which carries heavily traveled Interstate 405 through the Santa Monica Mountains where ridge tops are covered with expensive homes. At least two could be seen burning.Hundreds of firefighters battled flames on the ground as aircraft dropped water and retardant near neighborhoods on the east side of the pass. Commuter traffic snarled in the pass and beyond.When firefighters told Maurice Kaboud to evacuate his home in Bel Air he decided to stay and protect his home. The 59-year-old stood in the backyard of his multimillion-dollar home as fires raged nearby.“God willing, this will slow down so the firefighters can do their job,” Kaboud said.Hundreds of homes burned in the area during the famous Bel Air Fire of 1961. The Getty Center art complex, on the west side of the pass, employs extensive fire protection methods. Its website says it was closed to protect its collection from smoke.Elsewhere, use of firefighting aircraft has been constrained by the same winds that have spread the fires.The planes and helicopters essential to taming wildfires have been mostly grounded because it’s too dangerous to fly them in the strong wind. Tuesday saw gusts of over 50 mph (80 kph).Commanders hoped to have them back in the air Wednesday to battle flames that spurred evacuation orders for nearly 200,000 people, destroyed nearly 200 homes and remained mostly out control.“The prospects for containment are not good,” Ventura County Fire Chief Mark Lorenzen said at a news conference Tuesday. “Really, Mother Nature’s going to decide when we have the ability to put it out.”Southern California’s Santa Ana winds have long contributed to some of the region’s most disastrous wildfires. They blow from the inland toward the Pacific Ocean, speeding up as they squeeze through mountain passes and canyons.The largest and most destructive of the fires, a 101-square-mile (262-sq. kilometer) wildfire in Ventura County northwest of Los Angeles, had nearly reached the Pacific on Tuesday night after starting 30 miles (48 kilometers) inland a day earlier.The wildfire jumped the major artery U.S. Highway 101 to a rocky beach northwest of Ventura, bringing new evacuations, though officials said the sparse population and lack of vegetation in the area meant it was not overly dangerous, and the highway was not closed.The fire had destroyed at least 150 structures, but incident commander Todd Derum said he suspects hundreds more homes have already been lost. Firefighters have been unable to assess them.Lisa Kermode and her children returned to their home Tuesday after evacuating Monday to find their home and world in ashes, including a Christmas tree and the presents they had just bought.“We got knots in our stomach coming back up here,” Kermode said. “We lost everything, everything, all our clothes, anything that was important to us. All our family heirlooms — it’s not sort of gone, it’s completely gone.”Mansions and modest homes alike were in flames in the city. Dozens of houses in one neighborhood burned to the ground.John Keasler, 65, and his wife Linda raced out of their apartment building as the flames approached, then stood and watched the fire burn it to the ground.“It is sad,” Keasler said. “We loved this place. We lost everything.”Linda Keasler said they were just glad to be alive despite losing so much.“Those things we can always get back,” she said. “The truth is it is just things and thank god no one died.”Some 12,000 structures were under threat.A spokesman for the American Red Cross expected a shelter in Ventura County to be at capacity Tuesday night. Fred Mariscal said the shelter is serving meals, providing a mobile shower truck and has doctors and nurses on hand to provide medication for residents who were displaced by the wildfire.While the blazes brought echoes of the firestorm in Northern California that killed 44 people two months ago, no deaths and only a handful of injuries had been reported.In the foothills of northern Los Angeles, 30 structures burned. Mayor Eric Garcetti said the gusty winds expected to last most of the week had created a dangerous situation and he urged 150,000 people under mandatory evacuation orders to leave their homes before it’s too late.“We have lost structures, we have not lost lives,” he said. “Do not wait. Leave your homes.”Fires are not typical in Southern California this time of year but can break out when dry vegetation and too little rain combine with the Santa Ana winds. Hardly any measurable rain has fallen in the region over the past six months.Fires in suburban settings like these are likely to become more frequent as climate change makes fire season a year-round threat and will put greater pressure on local budgets, said Char Miller, a professor of environmental analysis at Pomona College who has written extensively about wildfires.“There are going to be far greater numbers that are going to be evacuated, as we’re seeing now,” Miller said. “These fires are not just fast and furious, but they’re really expensive to fight.”In LA County, television shows with large outdoor sets including HBO’s “Westworld” and CBS’s “S.W.A.T.” halted production of because of worries about the safety of cast and crew.And the Los Angeles Rams of the NFL, which hold workouts near the Ventura County fire, canceled practice Wednesday.

New soft motor more closely resembles real muscles w video

Your hand is a soft machine. To be able to mimic the hand, we need soft technology.” Citation: New soft motor more closely resembles real muscles (w/ video) (2011, April 18) retrieved 18 August 2019 from https://phys.org/news/2011-04-soft-motor-resembles-real-muscles.html Replacing batteries may become a thing of the past, thanks to ‘soft generators’ PausePlay% buffered00:0000:00UnmuteMuteDisable captionsEnable captionsSettingsCaptionsDisabledQuality0SpeedNormalCaptionsGo back to previous menuQualityGo back to previous menuSpeedGo back to previous menu0.5×0.75×Normal1.25×1.5×1.75×2×Exit fullscreenEnter fullscreen Explore further Play The first motor is a single membrane orbiting gear motor. Electrical activation of the membrane causes the central gear to orbit and the orbital motion of the gear turns the shaft. The second motor has the flexible rubbery gear. Electrical activation of the membrane can make the flexible gear assume an elliptical shape and grip the shaft. We can then move the electrical activation around the membrane so that the major axis of the ellipse rotates. When this happens the shaft is turned. The flexible gear motor has no rigid bearings and so it is possible to tilt the shaft up and down and side to side. Video credit: Iain Anderson Taking the idea further, Anderson had the idea of making the gear flexible so it could grip the shaft, like a thumb and forefinger grips a spoon. “This breakthrough made the bearings redundant, opening the door to multi-degree-of-freedom motion.” These degrees of motion include the abilities to tilt and rotate, in addition to simply moving the shaft up and down or side to side.In order to make the motor, Anderson and his group take a special polymer material and stretch it so it becomes a really thin membrane. They create a rubbery gear from the same material and then place the gear at the center of the membrane. Then, sections of the membrane are painted with carbon grease. This grease, when conducting electricity, forces the membrane to change shape and this causes the gear to deform, moving the shaft. “We use selective actuation to turn the shaft.” Anderson is a scientist at the Biomimetics Laboratory at the Auckland Bioengineering Institute in New Zealand. Anderson’s lab works with dielectric elastomer artificial muscles, developing technology designed to more closely mimic the movements of muscles. “We’ve been researching artificial muscles for a few years now, and we wanted to see if we could create a machine without any hard bits – a machine that mimics the same degree of freedom you see when you move your hand.”With the creation of a bearing-free motor, Anderson worked with others from the Biomimetics Laboratory, including Tony Chun Hin Tse, Tokushu Inamura, Benjamin O’Brien, Thomas McKay, and Todd Gisby. Their work can be seen in Applied Physics Letters: “A soft and dexterous motor.” Anderson says that the idea for an artificial muscle membrane motor came from his students a few years ago. They showed him an interesting motor. “They were working on this quietly amongst themselves. When they got it running they showed me. This had a rigid central orbiting bearing that was pushed side to side by one membrane and up and down by another,” Anderson explains. The motor consisted of two different membranes pushing on the same gear, with a shaft supported by rigid bearings. Anderson continues: “So we could get the gear to orbit by combining motion from both membranes and when the orbiting gear supported by the membranes came into contact with a gear on the shaft, the shaft rotated.” Artificial muscles are not new, Anderson points out. He says that SRI pioneered much of the technology used in artificial muscles today. SRI also produced an artificial muscle rotary motor. This first artificial muscle rotary motor, though, “had a lot of hard bits in it. But by using the membrane approach we have been able to make a rotary motor with fewer hard bits.”The ultimate goal is to create soft machines that are completely free of hard bits. There are advantages to soft motors, Anderson says. “They are lightweight and have the advantage of reduced mass. Their flexibility makes them less likely to break. Additionally, living things are mostly soft. If we want them to interface with living things, it makes sense to have them soft.”Anderson says that the next step is improve the control they have over the motor, as well as create a mechanism that allows the motor to automatically adjust to a heavier load – in much the way that your arm adjusts to keep your hand from lowering a glass of water as you fill it. “We’re into soft generators as well,” he continues. “We’re trying to make the world soft.” This document is subject to copyright.
