[Objective] Different from traditional underwater vehicles, the squid-like underwater robot has the advantages of low noise and good maneuverability. In this paper, the system design of the squid-like underwater robot was studied, including the mechanical structure design and drive system design. [Methods] The dynamic model of the squid-like underwater robot, the kinematic model of the undulating fins and the mapping model from propulsive force/torque to traveling wave parameter were established. [Results] The prototype of the squid-like underwater robot was developed. Then, multiple motion patterns such as marching, receding, turning, submerging and surfacing were achieved and tested. Besides, depth control experiment was performed. [Conclusion] Experimental results show that the squid-like underwater robot propelled by undulatory fins has good mobility.

Key words: biomimetics, squid-like underwater robot, system design, motion control
