Abstract
We are developing a human-symbiotic robot, called "EMIEW2", designed to support human activity. We set the following three features in the EMIEW2. The first is speed. The robot's moving speed is faster than human walking at 6km/h. The second is the safety. It weighs 13kg the same as a two-year old child. The third is its minimum size for office work. The robot's height is 800mm, which is taller than most office desk. This allows the robot to detect objects on them. To expand on the robot's range of motion, the EMIEW2 has three modes. In "two-wheeled mode", the EMIW2 can move nimbly at 6km/h. In the "four-wheeled mode", the EMIEW2 can move stably. In "step mode", the EMIEW2 can walk up a 3cm step. This paper describes the EMIEW2's mechanism and system constitution.
