| Overview |  In
pursuer-evader game (PEG), a vehicle (the evader) is driven
through a sensor field that is tracking its location and routing
its location to another device (the pursuer) that tries to
capture it autonomously. We deployed multiple versions of PEG
where the pursuer was a pan/tilt camera, an autonomous robot, or
simply a display on a screen. The evader varied from humans to
RC cars to pioneer robots. The most recent iteration used
passive infrared (PIR) sensors to track any moving objects in an
area covering 50,000 square meters with over 550 solar-powered
sensor nodes (Aug, 2005). Previous iterations used acoustic sensors
to track remote-controlled vehicles with a camera (Jan, 2002) or
magnetometers to help one autonomous, mobile robot to catch
another (Aug, 2003).
