Analysis of dynamic stability constraints for a mobile humanoid robot

This paper firstly presents a method to formulate the dynamics of the mobile humanoid robot which is composed by the mobile platform and the upper body. As tip-over is an important stable issue for the mobile robot, the dynamic stability constraint is carefully studied to keep the robot stable. Stable support for the robot moving on a plane is solved. With the consideration of the stability problem during the solution of inverse kinematics, the tip-over preventing constraint is applied to get the optimized solution. Finally computer simulations are carried out with and without the consideration of tip-over preventing constraints respectively.
