基于RRT * 的移动机器人动态路径规划与重规划

Dynamic Path Planning and Replanning for Mobile Robots using RRT*

University of Nevada, Reno(内华达大学里诺分校)

Devin Connell, Hung Manh La

摘要:

移动机器人必须能够有效地规划从其起始位置或当前位置到期望目标位置的路径。当环境是静态的时,这是一个微不足道的任务。然而,机器人的操作环境很少是静态的,并且它经常具有许多移动障碍物。机器人可能会遇到这些未知和不可预测的移动障碍物中的一个或多个。机器人在遇到障碍物时需要决定如何前进,提出了一种基于RRT* 的动态重规划方法。当未知的随机运动障碍物阻挡路径时,机器人将修改其当前的规划,各种实验结果表明了该方法的有效性。

英文摘要:

It is necessary for a mobile robot to be able to efficiently plan a path from its starting, or current, location to a desired goal location. This is a trivial task when the environment is static. However, the operational environment of the robot is rarely static, and it often has many moving obstacles. The robot may encounter one, or many, of these unknown and unpredictable moving obstacles. The robot will need to decide how to proceed when one of these obstacles is obstructing it's path. A method of dynamic replanning using RRT* is presented. The robot will modify it's current plan when an unknown random moving obstacle obstructs the path. Various experimental results show the effectiveness of the proposed method.
