摘要:

我们提出了一种新的方法来执行高自由度的机器人和高自由度的障碍物在动态,不确定的环境中的概率碰撞检测。在高自由度机器人和移动障碍物的动态环境中,我们的方法有效地计算机器人和障碍物之间的准确碰撞概率的误差上限。此外,我们描述了一个预测算法,未来的障碍物的位置和运动,占空间和时间的不确定性。提出了一种基于概率碰撞检测的高自由度机器人在动态、不确定环境中的轨迹优化算法。我们强调运动规划性能在具有挑战性的情况下,机器人手臂在动态移动的人类障碍物的环境中操作。

英文摘要:

We present a novel approach to perform probabilistic collision detection between a high-DOF robot and high-DOF obstacles in dynamic, uncertain environments. In dynamic environments with a high-DOF robot and moving obstacles, our approach efficiently computes accurate collision probability between the robot and obstacles with upper error bounds. Furthermore, we describe a prediction algorithm for future obstacle position and motion that accounts for both spatial and temporal uncertainties. We present a trajectory optimization algorithm for high-DOF robots in dynamic, uncertain environments based on probabilistic collision detection. We highlight motion planning performance in challenging scenarios with robot arms operating in environments with dynamically moving human obstacles.
