Its purpose is to give a basis for robots with drive and steer motors. I wanted to build a compact model, with a maximum flexibility to place sensors.
Several options are allowed
- One or two front touch sensor can be used. (The axle joiner must be removed)
- Light sensor can be placed in several places.
- A third motor driving a light sensor can be placed above the front wheels.
- The RCX can be placed freely on the top of the basis.
