It is very important for walking robot to have high mobility on uneven or hazard terrain. The mobility is closely related with the leg mechanism of walking robot. In this work, new orthogonal leg mechanism with P-R-P joints is introduced to increase the mobility. And new ankle of which rotational joints can be fixed or free depending on circumstances is proposed. Using the ankle is expected to relax the stability constraints. A quadruped walking robot is implemented with the proposed leg mechanism.
