This prosthesis using the technology called electromyography collection electrical signals from the forearm muscles.Through taut biceps, can control a motor, and transform the movement speed of the prosthesis, and its degree of loose and tight grasping the drumsticks
The robot drum prosthesis is from Atlanta, Georgia college of music and media - professor weinberger (left).Jason Barnes (right), said: "I bet many metal drummer will envy I can do for now."Dispatch of sina science and technology According to foreign media reported Thursday, Atlanta's drummer Jason Barnes, two years ago in a hotel, clean ventilation hood, misfortune electric shocks, lost his right arm below the elbow part.Fortunately, however, now he got a chance to realize music dream once again, has become a real "machine" musicians.
After the accident, Barnes decided to continue to do the drummer, so he tied a brace and some spring to his limbs, oneself give oneself create a prosthetic device.With the aid of the prosthesis, move up and down through the elbow, he can be the drums, but since there is no wrist or fingers, he could not control the speed of the drumstick or bounce.In spite of this, the device is still help him into the Atlanta, Georgia institute of music and media, and met Jill here - professor weinberger.Weinberg produced a bold plan to build a single rod device, the device can react to Barnes biceps.Barnes said: "now I can by contracting the muscles, to hold or loosen the drumstick signals from a computer, in order to control its rebound."The robot drum prosthetic engine, used to power two drumsticks.
The first root drumstick by musicians arm and electromyography (EMG) muscle sensor this way of electronic control.Barnes by taut biceps, can control a motor, and transform the movement speed of the prosthesis, and its degree of loose and tight grasping the drumsticks.Another "listening" drumstick of music will be playing and improvisation.This drumstick motor control by itself.It also with the aid of a microphone and an accelerometer, get to know the Barnes drum moves, and surrounding musicians play the music rhythm.Then it will be added using computer algorithms to generate new beats, the algorithm of imitation is John kotter and munch theron nice - such as jazz musicians.Georgia's music technology center, the founder of the weinberg said: "the second root drumstick have their own ideas. The drummer, in fact, has become a robot and a half. See him with this from him full control of artificial limbs performance and improvisation, is a very interesting thing."
Weinberg had previously made a robot percussion band and marimba player, they use a computer algorithm with human musicians impromptu performances.But Barnes of the prosthesis made another step towards his achievements, he has grown to a second root drumstick "music" brain.The professor explained: "Jason wants to completely control prosthetic limbs, he can move the upper arm, make remote control drumstick from drums. Or he could let it play on their own, and from his arms on the drums inspiration in response."The new prosthesis has made the Barnes has he had never had before amputation.Gw is now using the national science foundation funding, to further develop the technology.He said: "music is sensitive to time. Can you recognize the difference between knock twice, even if they are separated by only a few milliseconds. If we can use the machine to know Jason muscles, and determine when he intends to drums, and at that point in time, two arms can achieve synchronization."
Weinberg, according to the future in the more strict demands on time in the operation, the remote synchronization technology could be used to control an implantable, mechanical third arm.Weinberg, for example, the algorithm can be used to help astronauts or the surgeons to perform complex physical tasks with remote control equipment.For Barnes, the machine arm has prompted his skills to qualitative change.Due to an implanted chip can control the speed of the drum stick, so the prosthesis can use two kinds of different rhythm percussion two drumsticks.It can also be used beyond human ability and speed of mobile drumstick.Barnes said: "I bet many metal drummer will envy I can do for now. Speed is always the sooner the better."
