As part of our Bachelor of Science design project, we (J. de Bruijckere, R. Smit and L. Valk) have developed a mechanical, electrical and software design for a lightweight, mobile exploration robot that employs the half-circle leg morphology. The morphology is based on TU Delft’s Zebro robot, which in turn is based on the RHex...

Remember the MinuteBot Baseplate Kickstarter project? It was funded successfully, so the base plates have been turned into a real product. I’ve received a few plates last week as part of the pledge I made to the project. I’m quite satisfied with the quality of the product. They’re strong and hold LEGO pieces well. Obviously,...

This project is based on my universal balancing robot code. These small balancing robots are fun, but I wanted to make something that more closely resembles a real Segway. Alpha Rex gives sends ‘high-level’ commands like steering and speed to the Segway via Bluetooth. The Segway program turns these signals into movement. In the video,...

I got this set a while back and last week I finally found some time to build it. While building I couldn’t resist adding some extra features. I added 4 motors in total to make this car drive and steer with the Power Functions remote control. The video shows each of these additions in detail,...

This machine was developed for Mechatronics class – second year bachelor Mechanical Engineering at TU Delft. It’s made from FischerTechnik because these were the tools available in class. Note that some LEGO parts (the linear actuator) made it in here. In fact, the idea was inspired by the LEGO Milling Machine by Arthur Sacek. The...

You’d think I’d be bored with self balancing robots by now but I’m not! The Technic Unimog has huge wheels and I thought I might as well put them on Anyway. Then I thought that one wheel might be enough to stay up right, and it was. I know this is not a true unicycle,...

This machine plots drawings on standard A4 or US letter paper. The robot is featured in the NXT 2.0 Inventor’s Guide. Building and Programming this Robot Instructions for building and programming this robot are included in The Unofficial LEGO MINDSTORMS NXT 2.0 Inventor’s Guide (English) and in LEGO-Roboter II (German). It can be built with...
