tl;dr the function and training of humanoid robots includes no proprioception just inertial feedback as the device follows a routine set down in the training program. The device doesn't inhabit its environment the way a person does, it injects large amounts of energy to a relatively large mass, and is hard as a rock, so if you end up in its way you'll be clobbered by a device that powers through all it's motions lacking situational awareness and with no coordinated measure of an incidental fine touch.
