Externally, the robot Alice has dozens of sensors and other technology, including two GPS units and about seven lidar devices, which detect lanes and objects on the road. A short-range lidar sensor picks up obstacles like potholes, and a Riegl sensor observes long-range lane lines.
Radars estimate the distance of a vehicle ahead. On the roof of the car, there's a pan tilt unit (PTU), which can home in and focus on parts of the road or objects. The pole includes a TV camera, radar and lidar.
