Drummers mechanical arm

In 2014, a Georgia Tech professor help a drummer who had his arm amputated get back to drumming by creating a mechanical arm that drums for him.Now they have created a arm that is 30% louder. An arm that knows what your playing, know here the drum is and it can be used for many proposes like help hand tools to the doctor. This tool can adapt to anything your doing playing drums grabbing things, it might even help you color in the lines.The robotic arm is controlled by the person that is wearing  the person is fully in control of the arm and the arm does that you tell it to.The arm might be better then a human drummer and the person should be wearing a EEG headband which should send signals to the arm retrieving patters.The EEG head band sends messages to the arm telling the arm what to do all you have to do is think of what you want the arm to do and it will do that.
