PR2 handing an object over using a ROSCo behavior. This behavior demonstrates using the face detector module to define an arm trajectory for handing over objects. It also demonstrates using the tactile sensor to detect when users make contact with the object being held to know when to open the gripper.
Expert interfaces, or "Photoshop for robots" systems such as ROSCo demonstrate the potential of involving non-roboticists in making robot behaviors. Behaviors like this used to be the subject of entire robotics papers; now they can be constructed in about half an hour by non-roboticists and shared on the web.
