Robot obstacle avoidance optimization by A* and DWA fusion algorithm. [PDF]
PLoS OneThe current robot path planning methods only use global or local methods, which is difficult to meet the real-time and integrity requirements, and can not avoid dynamic obstacles. Based on this, this study will use the improved A-star global planning algorithm to design a hybrid robot obstacle avoidance path planning algorithm that integrates sliding ...
