SoundMachine is a LEGO drum sequencer that “builds” music using standard LEGO bricks. SoundMachine is an interactive music tool to collaboratively develop music. SoundMachine scans 2×2 colour LEGO bricks arranged in 4 tracks of 8 beats. The colour information is converted to MIDI messages by a Processing sketch, which sends MIDI to Ableton Live [...]
The new LEGO 9398 RockCrawler is out, and I really enjoyed how the designers chose to mount the motors directly on the pendular axles. Looking at it I realised that by replacing the power-function motors with NXT motors I could make the RockCrawler driven by the NXT. I had a new NXT2WIFI sensor from [...]
In celebration of the centenary year of Alan Turing’s birth Jeroen van den Bos and Davy Landman at Centrum Wiskunde & Informatica (CWI), Amsterdam (Netherlands) built a LEGO version of a Turing machine – the universal computing device that theoretically models how all computation is done. You can read about it at LEGO Turing [...]
Mike Brandl is a fellow LEGO MCP and all-round outstanding LEGO builder. His latest project certainly pushes the envelope when it comes to putting the NXT in a harsh environment. This time he has built a LEGO submarine that can navigate successfully underwater. The NXT is housed in a plastic sealed bag, with glue [...]
My Queboid robot has been around for a while, but for the World Robot Olympiad event in Abu Dhabi this year I decided to add a Zamor sphere shooter to the basic model. I swapped out the power function motors to use NXT motors. The idea was that kids could drive the robot using Philo’s joystick design communicating over Bluetooth [...]
You might remember the original Lego Street View Car I built in April. It was very popular at the Google Zeitgeist event earlier this year. I wanted to re-build the car to only use the Lego Mindstorms NXT motors. I was also keen to make it look more….car-like. The result, after 4 months of experimentation, is version [...]
This project is a LEGO version of the Google Street View Car. I’ve been working on this project for the guts of six months now, and you can probably see why! It all started when was playing with the dGPS sensor from Dexter Industries, and realised that if I combined this sensor, with a robust chassis and a [...]
I made some modifications to my LEGO Street Sweeper to bring to the LEGO World Zwolle event. The previous version lacked a finished body, so I added a rear body enclosure and a cab frame to make it more realistic.
After a long break I’m back with a new project. This autonomous street sweeper was inspired by the type we have driving around here in Ireland. It started as a simple project to build a 3-wheeler trike using a turntable, and like most LEGO it morphed into something else entirely.
Grab-n-Go is a NXTCAM controlled vision robot that can locate and pick up a red ball. It combines the drive motor assembly from the 8275 Bulldozer, the track supports from the 8294 Excavator, and Paul Tingey’s Clamp-n-Lift.
