For many drummers, losing a hand means one thing - ending a career. But not for Jason Barnes. Gil Weinberg, a professor at the Georgia Institute of Technology, designed the prosthetic brush, which not only restored the basic functions of Jason’s hand, thereby allowing him to play as before, but also improved it. Now the drummer has three hands. How does he play with two sticks with one hand? The first drumstick is controlled by the biceps muscle, the second automatically knocks out a custom rhythm. Thus, an unusual game technique is obtained, which will not be easy to repeat even for professionals. As you can guess, this kind of robotic arm gives a huge advantage to metallers and other performers of the “heavy” genre, where complex drum parts are of great importance. Moreover, Gil Weinberg believes that such a prosthesis can be useful not only for musicians, but also for people with disabilities in other areas. According to Gil, astronauts and surgeons may well perform complex tasks in the presence of a prosthesis. On March 22, 2014, this prosthesis will be presented at the Robotic Musicianship at the University of Kennesaw, Georgia.
