These remote control designs can be used for RCX remote communication. One design resembles a ‘steering wheel’, while the other looks more like a common joystick. Click to download the joystick source code and the steering wheel source code.

This robot turned out to be the first in a series of climbing robots. The primary function is simple: climb straight up between two vertical walls. Pretty boring, but amusing enough to get 600,000 Youtube views. I created it as part of a “community Contest” in the legacy RCX MINDSTORMS forums. The goal was to...

This car is a combination of the RIS 2.0 set with several parts of the #8421 crane set. The back wheels are driven by one motor, which also makes an ‘engine’ run. A motor in the front allows for steering using a rack-and-pinion steering mechanism. A touch sensor in the front detects a bumper press...

This is just a fun little model designed to try out some gearing functionality. It couldn’t turn very well due to it’s tyre construction, and the lifting mechanism resolves this problem. It features the Lego Speed Computer as a rotation sensor. This vehicle was designed in November 2006.

This railway crossing lowers the barriers when the light sensor detects that a train is approaching. After that, the bridge is raised, allowing the train to move along. The reverse occurs after a given amount of time — when the train has passed by. This construction was designed in May 2006.

A robot that sorts LEGO bricks is possibly one of the most popular MINDSTORMS projects. They’re interesting to build and to watch when they’re sorting bricks! This is the first working brick sorter that I designed, and it was inspired by ” brick sorter 3” by fellow brick sorter builder Philo. This robot was designed...

MINDSTORMS Walkers come in all sizes and leg counts, and this one is my first attempt at creating one. Whether it’s really walking is debatable, but it’s moving, and not on wheels! 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...
