A robot displacement device for use with a robotic frame shaped to approximate and be coupleable to at least a portion of the human body and configured to mimic movement of the human body The device employs a plurality of force sensors, which are attached to the robotic frame which detect a baseline controlling interface force status relationship between the sensors and the extremities of the human operator Based on the output force signal from the sensors, and the force and direction of gravity relative to the robotic frame, a computation system calculates at least a rotational force required to maintain the controlling force status relationship The computation system then generates and transmits an actuation signal to a drive system attached to the robotic frame which displaces a portion of the robotic frame in order to maintain the controlling force status relationshipread more
