This paper presents a practical solution to the problem of multi-legged robot’s stability using a multi-contact approach applicable to unstructured terrains. The solution is based on a modified version of the Contact Wrench Set method which utilizes three arbitrary contact points to represent the physics of contact to test for stability. The developed method targets a variety of terrains including heterogenous surfaces extending the capabilities of the traditional Contact Wrench Set formulation. In this paper, the corresponding theoretical formulations and a novel visualization tool representing the robot’s stability level are presented. Thorough verification of the new formulations is investigated via multi-body dynamic simulations. Experimental tests using a life-size humanoid robot show that the approach effectively quantifies the robot’s stability on a wide range of surfaces.
