Collision Free Navigation with Interacting, Non-Communicating Obstacles

Abstract

The talk addresses navigation in an environment occupied by other interacting agents (e.g. vehicles, robots, pedestrians, pods) that cannot communicate to one another. In contrast to the path planning problem, the difficulty here is that agents cooperate and compete, creating feedback loops each only partially controls. The talk starts with a very high level overview of two control design methods: Model Predictive Control (MPC) and Control Barrier Functions (CBF). The MPC is powerful, yet computationally expensive. The CBF approach is computationally simpler and handles non-convex constraints gracefully, while, being recently introduced, is only partially understood. Performance of a CBF controller is illustrated with a real industrial robot avoiding a stationary cone.
