Shifting Gears: A NXT Vehicle with a Transmission

Saturday, November 4th, 2006

This creation is really more about modelling cars than about robotics. One NXT motor drives the car, a second NXT motor steers it, and a third controls the transmission. Apart from the NXT brick, the motors, and the touch sensor, the parts are not from the NXT kit. Most of the parts are from Lego set 8421, a large Technic crane. The full description of this vehicle contains a video and many more images. Don’t miss the video!

ruby-nxt 0.8.1 Now Available

Saturday, November 4th, 2006

Tony Buser’s ruby-nxt gets an update to version 0.8.1. ruby-nxt is an interface written in the Ruby programming language that allows Bluetooth control of the LEGO Mindstorms NXT.

Not much new in this release. Mainly a few fixes to allow ruby-nxt to be packaged into a gem, finally! You also might find the examples/drb_server.rb interesting - a simple DRb server that keeps the bluetooth connection alive.
