II. The Anthropomorphic Assistance Robot Cora CORA(=Cooperative Robot Assistant, see Fig. 1) was built as a prototype of a service robot system to assist a human partner in industrial assembly tasks. The research on this platform ranges from investigating the behavioral aspects of man-machine interaction and the representation and interpretation of scenes to the generation and organization of behavior. In our opinion successful man-machine interaction requires that both, the robot and the human partner, possess a similar sensor- and effector equipment. Therefore, we designed CORA anthropomorphic: the seven DoF manipulator is connected to a one DoF trunk which is fixed on the edge of a table. Above the trunk we assembled a two DoF pan/tilt unit carrying a stereo color camera system and microphones. By turning the trunk joint, the robot can change its configuration from left to right handed.
