Abstract: A dynamical servo control strategy was proposed to control the terminal of an underactuated 2-link robot to track a given trajectory or an object during its brachiation. The single pendulum like brachiation of primates was simulated,the control rules for a sliding mode control based on energy and the spatial structure of the 2 links were designed using the Lyapunov stability theory,and the dynamic position control of the terminals of the system was achieved. Simulation results verified the effectiveness of the designed control strategy. -
