This is the NK-01 prototype mecha exosuit, a robotic shell designed to be piloted by a human from inside. Chinese tech company FutureWise has been developing the robot exosuit from their headquarters in Beijing for years, and it looks like they are getting quite close to achieving their vision. FutureWise is one of the only three teams in the world currently producing exoskeleton that can be piloted by humans from the inside.
