Path Planning Algorithm in Dynamic Environment Based on Improved Dynamic Window Approach
In scenarios involving autonomous robot motion and target tracking,the presence of dynamic obstacles can pose a threat to real-time planning.Therefore,generating a safe path to ensure that robots do not collide with dynamic obstacles becomes paramount.An improved dynamic window approach(DWA)algorithm based on the concept of velocity obstacles(VO)was proposed.By considering the velocity of obstacles,obstacle-based danger zones was calculated and them for DWA node selection was used to eliminate infeasible paths.Additionally,an artificial potential field as an evaluation function was introduced to select the optimal nodes,ensuring collision avoidance with dynamic obstacles and quick attainment of the desired target point.Results indicate that the proposed DWA-VO algorithm exhibits higher success rates and superior planning quality in dynamic environments compared to traditional DWA algorithms.
