Abstract: The present invention provides a multiple-point grounding type foot portion supporting mechanism having excellent reliability, in which the respective supporting points passively follow unevenness of the grounding surface such as a road surface, and which is capable of quickly supporting foot bottoms at polygonal points and preventing falling over even on a grounding surface having level differences by fixing the supporting points when all supporting points are grounded.
Abstract: The present invention provides a quadruped walking robot the production costs and weight of which can be reduced by reducing the number of driving portions, and which is capable of carrying out stabilized walking motions even with the degree of freedom reduced in the leg portions.
