TED: A monkey that controls a robot with its thoughts. No, really.
From TEDMED 2012:
Can we use our brains to directly control machines? Miguel Nicolelis suggests yes, showing how a clever monkey in the US learned to control a robot arm in Japan purely with its thoughts. The research has big implications for quadraplegic people — and in fact, it powered the exoskeleton that kicked off the 2014 World Cup.
