- Abstract:
-
To solve the problem of mobile robot path planning in complex environments, a novel path planning method based on enhanced bacterial chemotaxis and an adaptive dynamic window algorithm is proposed. In addition to inheriting the benefits of bacterial chemotaxis and the dynamic window algorithm in avoiding obstacles, the novel method can also be used to avoid static or dynamic obstacles for mobile robots. It is typically divided into three steps when employed for mobile robot path planning. First, an initial referential planning path in a static environment is determined using the enhanced bacterial chemotaxis algorithm. Next, based on the reference path, the robot detects and avoids dynamic obstacles using its own sensors and completes path planning for local dynamic obstacle avoidance using adaptive DWA. Ultimately, the mobile robot chooses the next execution step based on the outcome of avoiding dynamic obstacles. If the robot is able to reach the final object point, the algorithm stops. Otherwise, the robot will return to the initial path until the final object point is reached. The comparison of simulation and experiment results demonstrates that the algorithm’s convergence speed and accuracy of path planning have been significantly enhanced.
