| (...) I've used a collection of four Scouts driven by IR commands from an RCX to drive a total of eleven motors. Just program the scouts to read simple 1-byte messages sent from the RCX - use the top two bits to select which Scout you are talking (...) (23 years ago, 10-May-02, to lugnet.robotics)

| I am not a big fan of Lego pneumatics either, but they are so light weight and a perfect solution in your application. The micromotors have so little power, that you would have to gear them down to get any holding power for your grippers. Then (...)
