Embodiment Construction
[0043] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0044] The invention relates to a motion planning method for an underwater robot, in particular combining multi-objective constraints and a reinforcement learning method for the motion planning of the underwater robot. Model construction stage: transform the robot obstacle avoidance sonar signal and the flow velocity signal of the flow velocity sensor into the current environment; establish a discrete action space based on the dynamic constraints of the underwater robot; establish a reward function with underwater obstacles as constraints; The goal constraints establish the Markov decision process and establish the basis for the algorithm implementation. Training phase: training based on the Q-learning algorithm. In the current environment, actions are executed based on the greedy strategy. Every time the strategy is executed, the strategy is eval...
