In this talk, we present our recent contributions in utilizing networked mobile robots as collective sensing agents to explore unknown environments. Two scenarios will be discussed. In the first scenario, a group of agents are deployed to construct the Voronoi diagram of a complex 2D workspace and to construct a sensing/communication network. Then the network is utilized to capture intruders to the workspace. We rigorously justified the completeness of the algorithms and provided an upper bound on the number of agents necessary to capture all intruders despite of the superior mobility of the intruders over the agents. In the second scenario, the agents are deployed to explore the level surfaces of a 3D noisy scalar field. We extends our cooperative Kalman filter previously developed for 2D scalar field to incorporate more challenging geometric structures in 3D fields. The algorithms developed may be used to explore underwater hypoxia regions. In both scenarios, we perceive a common theme of tightly integrated sensing, control, and communication research.
