Cooperative motion planning for human-operated robots

Kris Hauser


This project aims to advance decision-making techniques for robots that cooperate with human operators. Because humans far exceed the abilities of state-of-the-art robots in vision, creativity, and adaptability, interest is rapidly growing in a human-centered approach to robotics: combining the strengths of humans with the superior precision and repeatability of robots. And yet, our available motion planning tools, while powerful at computing motions for complex autonomous tasks, are poorly suited for human-centered applications that demand responsive and natural motions. We hypothesize that a new cooperative motion planning paradigm will support major advances in intuitiveness and task performance of human-operated robots such as intelligent vehicles, tele-surgery systems, search-and-rescue robots, and household robots.

Cooperative motion planning generates motions in real-time that avoid obstacles, even when the user's command (yellow) is unsafe.

Users with cooperative motion planning (CMP) solved problems on a 6DOF manipulator twice as fast as basic Cartesian control (IK), and at a 12x lower collision rate.

Users perceived CMP as significantly safer and providing a better experience than other techniques, while not significantly detracting from predictability and cooperativeness (asterisk denotes statistical significance at the p < 0.05 level.)
