A new type of anchor chain detection robot for offshore floating wind power platform is proposed. Compared with the traditional underwater robot, the robot crawls along the anchor chain during operation. Aiming at the new type of anchor chain detection robot, ADAMS software is used to simulate the movement of the robot along the anchor chain. On this basis, the obstacle surmounting ability of the robot in the inclined state is analyzed, and two cases of 45° and 60° are studied respectively to verify the rationality of the model design. The results show that the anchor chain detection robot runs smoothly in the process of moving, which meets the requirements of structural design, and also provides important data for optimizing the robot structure.
