It’s important that you make all the wires emerge from a point close to the

center of the primary turntable so they don’t affect its rotation. In large robots like

this, clean and well-organized wiring helps a lot in keeping things under control.

For the input of the human moves, we replaced the single touch sensor with a

slightly more sophisticated unit also made from a rotation sensor.This speeds up the

choice of the coordinates, changed according to rotations, displayed on the master

RCX, and confirmed by a click on the touch sensor (Figure 20.12).
