Robotics

Robotics is an interdisciplinary branch of engineering and science that includes mechanical engineering, electronic engineering, information engineering, computer science, and others. Robotics deals with the design, construction, operation, and use of robots, as well as computer systems for their control, sensory feedback, and information processing.

Either the Lego Mindstorms NXT-G or the RoboLab programming environment supports the RCX controllers.  Each programming language is graphical in nature allowing you to drag and manipulate motors and sensors to a workspace and link them together in a logical fashion before they are downloaded to your robot.
