This paper summarizes ongoing work with a mobile manipulator (Mobipulator). We describe the system architecture of the latest version of the robot, a hierarchy of robot motion commands (the Mobipulation library) that can be snapped together to generate complicated paths easily, a configuration space planner that plans wheel motions to manipulate paper, and a visual servoing system to monitor and correct errors in robot motion.
