Torque Constraints for Hexapod Robot Slope Walking

This paper focuses on the problem of the gait planning of a hexapod robot in order to improve its practicability. Gait planning based on the torque constraints and the stability margin constrains is proposed. The gait planning on the ground plane is introduced with combining with the mechanism specification of the hexapod robot, and the torque constraints and the stability margin constrains on the ground plane is proposed with the kinematic analysis and force analysis. Then the key constraints for gait planning on the slope are proposed to deal with a more realistic problem. The algorithm analysis can prove the variation of the key control variable under the two constrains. Simulation results are presented to support the proposed algorithm.
