Cooperative Trajectory Planning in Mobile Robotics

The motion of multiple mobile robots in the same operation area can lead to intersection situations that cannot be resolved by individual and uncoordinated trajectory planners. To establish a coordinated planning method, centralized and decentralized control architectures have been proposed. Centralized architectures require a central coordination unit that is responsible for transmitting trajectories or priorities to the robots. In decentralized approaches, trajectory planning is equally distributed among the robots and explicit or implicit communication between the vehicles is necessary to resolve the conflict.
The trajectory planning problems of the mobile robots in an intersection scenario can be formulated as coupled optimal control problems, representing a differential game in the context of game theory. The proposed decentralized game-theoretic trajectory planning techniques for interacting mobile robots are mainly based on non-cooperative game theory. In non-cooperative game theory, each player minimizes its own cost function and does not consider the negative influence of its chosen strategy on other players’ costs. As a result, social effects when multiple robots interact are not modelled.
Therefore, a decentralized and cooperative trajectory planner to efficiently resolve intersection scenarios without the dependency on a central coordination unit shall be developed. A preferably small percentage of explicit communication between the robots should be required.
