- Abstract:
-
Mapless navigation for mobile robots based on deep reinforcement learning (DRL) has received increasing attention from robotics and related research fields. The major challenge in mapless navigation is collision avoidance of dynamic obstacles in unstructured environments. Therefore, this paper proposes a DRL algorithm that incorporates a heuristic correction policy for robot autonomous navigation. The algorithm utilizes information from a 24-line laser radar sensor, target location, and robot velocity as inputs for DRL to generate action commands that regulate the robot’s motion. Experimental results demonstrate that, compared to other algorithms, the proposed approach can reach the target more efficiently in terms of distance and time while ensuring safety. Moreover, the algorithm is implemented in a real robot to verify and evaluate its performance, providing a technical reference for collision avoidance during its navigation in dynamic environments.
