The two ‘leg modules’ are identical and shown below. In the video, I’m using the RCX remote control to simply power motors A...

With limited building skills and a newly acquired second RCX, I built a somewhat ugly robotic base for the 8421 crane set, back in November 2006. The grabber is from the the Mindstorms Ultimate Builders Set. It features a Lego Speed computer as a rotation sensor. The crane module is more or less unaltered, except...

What else to say than, “Should have made a video”? Perhaps that this one was much easier to build than with the NXT! The two motors are connected directly to the RCX and to the motorcycle wheels. The vehicle is remote controlled by the RCX Remote control or by running a very basic random motor...

This room explorer was built in April 2006 when I just started building with LEGO MINDSTORMS. Not much to say about this one, other than that I probably used it to practice my building and programming skills. With the concept of a ‘sensor’ being new to me then (hey, I was 12!), there were enough...
