Abstract
The following quote was obtained by the news editors from the background informa tion supplied bythe inventors: “Mobile robots are roughly classified into a “fo ot” type robot capable of walking motionusing a foot-shaped structure and a “wh eel” type robot capable of driving motion using wheels. In thecase of the foot- type robot, non-flat environments, such as stairs or rough terrain may be easily overcome,but a movement speed on a flat ground is low, and energy use efficien cy is degraded. On the other hand,in the case of the wheel-type robot, a moveme nt speed on a flat ground is high, and energy use efficiencyis high, but drivin g performance is significantly reduced in non-flat environments, such as stairs or roughterrain.”
