This document discusses the applications of nanotechnology and microelectromechanical systems (MEMS) in robotics. It describes how nanotechnology involves engineering systems at the molecular scale, and how MEMS merges with nanotechnology at the nano-scale. Some applications of MEMS in robotics include uses in self-balancing robots, collision detection, and human motion monitoring. Specific MEMS devices discussed include accelerometers, geophones, digital compasses, oscillators, and microphones. The document also explores potential future applications of nanotechnology in areas like industrial robots, medical robots, self-replicating nanobots, and integrating nanotechnology with the human brain.
