A user can “experience” things and perform “tasks” as a second self of the user without being there in person. We position the avatar robot as 4-dimensional mobility beyond the 2-dimensional and 3-dimensional space-time. We consider the robot as “self-expansion without being bound by the constraints of time, space, or ability,” as well as “beyond-space-time expansion of the fields where human beings can act.” Aiming to create the robot that can work adapting to the environment where people live, we are striving to research and develop a human-like robotic hand that is “sensitive” and “powerful” and “AI-supported remote control technology” that corrects the discrepancies between human and robot vision or tactile sensation in order for a user to operate it freely.
