Human computer competition in game situation: motion planning for boxing

Abstract

This paper presents a motion planner for robots in a game situation, in which the agents involved have conflicting goals. More specifically, a human-computer boxing game system is developed in a graphical environment. One boxer is controlled by a human through a motion tracking system, while the other is controlled by a motion planning algorithm. The planner has a defensive and an offensive strategies. The defensive strategy tries to move one of the forearms between the opponent's fist and its body, while the offensive strategy locates an exposed part of the opponent's body and throws a punch at it. To achieve an interactive operation, the motion planner considers only kinematic and geometric constraints during the search. This project is also aimed at integrating a planner with all actual robot, and investigating associated technological bottlenecks.
