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...

Last update: 10 November 2012 This tutorial will show you how to use and modify RobotC program code to create a working LEGO NXT Segway that you can customize as you like. Although you can use any type of LEGO NXT Segway with this code, I am assuming you will use the ‘Anyway’ platform. I recommend...

This is the basic Segway platform that you will use in each of the Segway tutorials. The robot is often referred to as ‘Anyway’, because you can build this robot with ‘Any’ version of Mindstorms NXT. Apart from a (any) NXT set, you will need a Gyroscopic Sensor for balance measurement: Either the HiTechnic Gyroscope,...

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...

NXT-G won’t be the next step to singularity, but there’s still a lot you can use it for. I’ve recently been working with NXT-G to create a program for my balancing robots. I’ve done this in the past, but this time I wanted to create some clean and easy to use code that doesn’t require...

You know what happens to a lot of websites eventually. They become inactive, leaving new readers frustrated with messages like “Last update 2009”. I think that happened to my old website too. Not updating a website doesn’t always mean the author has stopped with what he worked on, though. For instance, I’ve been building robots...
