Rack and Pinion Car
Monday, July 30th, 2007
Cesar Barscevicius has put this nice video, demonstrating a rack and pinion drive, with each pair of wheels (front and back) driven by one motor+differential and the third motor rotate the front wheels using a well-built rack and pinion. I could not figure out the power transmission mechanism in the front wheels, but maybe the builder will send some more details (and I’ll be happy for building instructions for this project!).
UPDATE: I’ve got an email for Cesar. Indeed he used 4 double bevel gears, inspired by 222doc “AWD buggy 4×4x4″ NXTLog project. He has an NXTLog project page for this car here. I asked him for more photos and maybe building instructions - stay tuned!

NXTLiftBoy
Saturday, July 28th, 2007
A nice NXT project by NXTLiftBoy. According to his email, he used Java for this project to do fast proportional wireless control by a PC with a mouse. The programming allowed him to use BT remote control on the ‘wrong’ BT dongle and stack (Toshiba) which usually does not work. I hope he will send more details on this later.
Nice work, NXTLiftBoy!

NXT Radar - Part I
Saturday, May 12th, 2007
Here’s my latest project - a true NXT radar. The Sharp IR Distance sensor from mindsensors.com is mounted on a turntable on top of a mobile platform. The unique feature of this robot is that the sensor can be rotated infinitely, without tangling the cables, using a modified handset untangler.
A discussion topic is here. More details will appear soon…

NXT explorer
Tuesday, May 8th, 2007
Here’s a VERY nice looking ‘explorer’ NXT by forums reader PTP. This explorer uses 3 multiplexed touchsensors, the ultrasound sensor, a color sensor, and a compass sensor. The driving base is extremly compact using two motors for navigation and the remaining motor port is used to drive two alternating LEDs. More images and discussion in this post.

LocoArm: Robot Locomotion on Rails
Friday, April 6th, 2007
A robot that moves on rails can traverse large distances quickly and still reach its destination accurately, because it only needs to navigate a one-dimensional world. In this robot I used Lego train tracks from the RC Trains line, along with a train motor from the same line. The motor is a 9V motor that can be controlled by the NXT using a converter cable. The robot detects stations that have stands for a ball using the light sensor, but it was challenging to stop the robot precisely at the station.
Read all about it and watch a video!

NXT Warehouse
Thursday, March 29th, 2007
Here’s some awesome NXT warehouse made by guys in Cubido Gmbh. These guys used microsoft BizTalk Server to manage SMS messages to the “warehouse”, SQL Server 2005 for data storage and web services. Microsoft Workflow Foundation to create the processes controlling the warehouse robot. and Microsoft .NET (C# and C++) to program the whole stuff. They also made their own electromagnet controlled via I2C bus.
Their webpages (mostly German) are linked here. A great trailer video (with Lego people animation..) for BigDays 2007 is here. Great work!
