For PR2, an autonomous service robot, finding its way around an unfamiliar environment is certainly a complex task, yet by no means impossible! Using the 3D camera located on its “head” and its optical motion capture system, PR2 can sense its surroundings and learn to see what it can move, lift or press using its gripper. The screen displays the representation of the ongoing construction of its environment. The small objects that the robot has learned it can interact with are shown in yellow. Interaction upon interaction, PR2’s learning algorithm enables it to use its skills to build its own view of the world.
