See Lego robot controlled by DIY exosuit

Danny Benedettelli built a Lego NXT humanoid robot that he controls with a sensor-laden exosuit, known as a "waldo." For example, when he moves his arms, so does the robot.

Benedtettelli wrote the book Lego Mindstorms, literally: The LEGO MINDSTORMS EV3 Laboratory: Build, Program, and Experiment with Five Wicked Cool Robots
