Toyota's I-Foot.

Would you walk upstairs in one of these?

This 2-legged, mountable robot was developed for three-dimensional mobility, with the ability to navigate staircases. The passenger climbs on and drives with a joystick. Toyota will present this proposal for a new type of mobility at EXPO 2005 AICHI, JAPAN.

Design Concept
The egg-shaped design of the “i-foot” that wraps around the passenger is meant to express the dream of future three-dimensional mobility and the feelings of safety and reliability upon which that dream is built.
