Adaptive Obstacle Avoidance Algorithm for Robotic fish integrating Recurrent Proximal Policy Optimization and Improved Dynamic Window Approach

Jinghui Lin, Xuhong Huang

Abstract


To address the challenges of complex obstacle motion, motion control latency, and limited energy supply of robotic fish in
underwater aquaculture environments, the traditional Dynamic Window Approach (DWA) with a fixed weight mechanism exhibits poor
balance among obstacle avoidance safety, path smoothness, and energy efficiency. To this end, this paper proposes an adaptive obstacle
avoidance algorithm for robotic fish based on Recurrent Proximal Policy Optimization and Dynamic Window Approach (RPPO-DWA).
First, an improved DWA evaluation function adapted to the underwater three-dimensional environment is constructed by introducing
height error, dynamic collision risk, and energy consumption constraints to enhance decision quality. Second, the weight adjustment
process is modeled as a Partially Observable Markov Decision Process (POMDP), utilizing a Gated Recurrent Unit (GRU) network
to extract temporal environmental features and solving for the optimal weight vector online via RPPO. Finally, the Generalized StateDependent Exploration (gSDE) mechanism is introduced to suppress path oscillation. Simulation results demonstrate that, compared
with the fixed-weight DWA, the proposed algorithm significantly improves the obstacle avoidance success rate and navigation efficiency,
effectively achieving predictive obstacle avoidance and synergistic optimization of energy efficiency for robotic fish under conditions of
time delay and dynamic disturbances.
