Overview

AMIGO is an acronym for Autonomous Mate for IntelliGent Operations. AMIGO is a service and care taking robot of the Eindhoven University of Technology. It is used as a demonstrator in several projects, e.g., Bobbie Robotics and RoboEarth. Furthermore, it competes in the RoboCup@Home league on behalf of Tech United Eindhoven.
Figure 2 shows a picture of the CAD model of AMIGO. It roughly consist of:

• a head combined with a laser range finder to visualize the environment;
• two Philips Experimental Robotic Arms (PERA) interact with it surroundings; The PERAs are bought from Philips and are not open source released.
• a torso containing a spindle which enables AMIGO to translate the upper body in vertical direction;
• a base containing the batteries, electronics and four omni wheels.
