Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
Robotics may be the most inter-disciplinary of engineering endeavors. A mechanical engineer will design the robot's structure, its joint mechanisms, bearings, heat transfer characteristics, etc. Electrical engineers design the robot's control electronics, power amplifiers, signal conditioning, etc.
