The Big Robot Project in the PhD program in Empowerment Informatics, University of Tsukuba, aims to develop the world’s largest robot in which a pilot can ride and move. The Big Robot Mk1 has two legs with wheels attached at the bottom, and the pilot is positioned 5 m above the ground. The pilot controls the robot’s movement forward by moving his or her own feet. The robot is programmed to follow the path of a 5 m tall humanoid. Thus, the pilot feels as if he or she has the body of a 5 m tall giant.
