LEGO Mindstorms NXT Bin Emptying Robot – Mark I
This is Mark I of my LEGO Mindstorms NXT Ball Sorting Factory, which I have been working for a number of weeks. The whole project consists of three main parts. Firstly there is the 'Ball Sorting Factory', made up of Gantry System with 3-Axis: Front-Back, Left-Right, and Up-Down for the Ball Gripping Claw. The Second [...]
Quad Track: IR-Ball Seeking Crane
This is my LEGO Mindstorms NXT Quad Caterpillar Track Crane, which uses my 'Ultimate Grab' to pick-up and retrieve a Hitechnic Infra-Red Electronic Ball. The Chassis houses 2x NXT Motors to drive the Left and Right pairs of Tracks. A third NXT Motor is used to raise and lower the crane arm. A Small PowerFunctions [...]
The Mars Rotacaster Rover
Part I Lookout NASA, you have Rover competition. And it uses the amazing Rotacaster Omni-wheels for unsurpassed manoeuvrability in confined spaces. There is no need of a steering mechanism to turn the Rotacaster Rover thanks to the unique wheel design. NASA Mars Spirit Rover I've had a few attempts, going back to the days of [...]
Ball Sorting Crane with Ultimate Grabber
As mentioned in my previous post, I've been working on-and-off for a couple years now on a reliable LEGO Technics, Crane Claws which will pick up balls reliably. To show case my 'Ultimate Crane Grab', I've built a LEGO Mindstorms NXT Coloured Ball Sorting Crane, which runs along a geared tressel, which features my Ultimate [...]

Tri-wheeled Omni-bot Update II
Peter McKinnon from Rotacaster pointed out from looking at my last update the I've managed not to take into account that for proper Rotacaster Omni-wheels action to work on myOmni-directional robot, the wheels have to always remain parallel to the ground. When the legs were raised & lowered independently, or together the wheels where never [...]
Tri-wheeled Omni-bot Update
This is as far as I’ve managed to get without the proper Rotacaster Omni-wheels on my main Omni-directional robot. The legs can be raised & lowered independently, to lift the body 150+mm above the floor. The 3x Ultrasonic Sensors appear to be working together and measures the distance to objects o.k.I’m now working on programming the behaviours and using the Playstation 2 Controller.
Using Multiple Ultrasonic Sensors
If you wish to use Multiple Ultrasonic Sensors on your NXT Robot, you need to program them so only ONE Sensor is taking a measurement at any time. If you have all the Ultrasonic Sensors on at once they interfere with each other and give incorrect readings. To get around this you need to take [...]
The beginings of an Omni-wheeled Bot
This is the begining of what will hopefully become a Soccer Playing Bot eventually. I will fit a set of Rotacaster Omni-wheels to the bot when they become available in the Lego Technics format. Link to this post!
