The 500 - pound, 5 - foot - tall
robot was much larger
than the 12 - pound, 32 - inch - tall monkey whose neural signals were
directing it, and this underscored a simple yet remarkable point: Implant technology could enable brainpower to control a huge object (like a
robot crane) or a tiny one (like a microscopic surgical tool) just as easily as a life - size mechanical arm.
