Underwater experiment and analysis of three-joint crescent caudal robot fish

After the completion of the overall design for the robot fish, in order to validate correctness of robot fish machine kinematics and dynamics analysis and to learn whether each module can work reliably and achieve the desired objectives after processor coordination, an underwater experiment is needed to ensure the correctness of overall organization, the hardware circuit, the control of the software and the feasibility of the presented algorithm. We established the robot fish test system, conducted a series of experiments to verify the design´s requirements , and achieved the expected record data , which was helpful to furthering the design of robot fish.
