BigRobot: A Movable Motion Base Enhancing Walking Sensation

Abstract

The “Big Robot” has two legs with wheels, mounting the pilot at 5m height position. The robot goes forward according with the motion of the feet of the pilot. It is programed to make trajectory of head position of 5m giant. Thus, the pilot feels as if his/her body were extended to 5m giant. The biggest technical issue in large-scale robot is falling down to the ground. Thus, the base frame of BigRobot is made of steel and its linkages are made of CFRP. This structure enables low center of gravity and prevents from falling down. The Big Robot was exhibited at Ars Electronica Festival 2015, Tsukuba Media Art Festival 2015 and Emerging Technologies of SIGGRAPH 2016, that proved its effectiveness.
