Abstract
Compared with the snake-like underwater vehicle with steering gear, the snake-like underwater vehicle with soft joint connection is more flexible and compliant, and it also provides the possibility for the robot to contact with the environment. In this paper, a soft joint for underwater snake-like robot is innovatively proposed, and a test prototype of soft joint is developed. A soft joint attitude control strategy based on feedforward and feedback is proposed to realize high-precision pressure control of soft unit and underwater attitude control of soft joint. Based on the software and hardware control system of the developed soft joint, a test platform for soft joint control is established to verify the feasibility of the proposed soft joint and its attitude control algorithm.
