The first research area is coordinated control of communication-enabled mobile robots and vehicles. These robots are equipped with various sensors and on-board processors which are linked to other robots/vehicles and the surrounding environment. Our mobile robots emulate autonomous and connected vehicles with vehicle-to-vehicle (V2V), Vehicle-to Infrastructure (V2I) and Vehicle to other entities (V2X) (such as road users, pedestrians, bicyclists, etc.) communications. We are developing and evaluating hybrid hierarchical control algorithms for autonomous driving, platooning, merging, collision avoidance, and several other dynamic coordinated functions of intelligent vehicles and robots in complex environments.
