Abstract :
A novel biped robot and its control strategy are presented. The robot has cylindrical bar distributing in lateral plane as it´s feet, which can acts as a pivot when walking. Then the robot can realize completely dynamic walking. The hybrid dynamic model is developed and gait is planned using strategy of time-invariant. By the finite-time nonlinear controller, the robot realizes stable dynamic walking. Simulation results show that a stable limit cycle of dynamic walking is achieved, and proposed control strategy is feasible. Based on analysis of the relationship between walking velocity and robot configuration, a velocity control strategy is presented and validated by simulation.
