Introduction: Wii-NunChuck Controlled Mindstorms NXT Soccer Robot

For the Brixhibition Exhibition at the end of April, I was asked to set-up and run a couple of interactive Robot Soccer fields.The Robots needed to be robust and reliable as members of the public will be interacting with them. Also they need to have a a simple, intuitive, and easy to use hand held controller. I have used Sony Playstation PS-2 Controllers, but they have far too many controls that would be unused and confusing to the first time operator. I chose to use a Nintendo Wii® Nun-Chuck Controller for the job as the Nintendo Wii® Nun-chuck Controllers are very robust, intuitive and fit virtually any size hand.

Step 1: Details

The Dexter Industries®‘ NXTChuck allows you to control your LEGO MINDSTORMS robot with the Nintendo Wii® Nun-Chuck. Simply plug the digital adapter into any sensor port on your LEGO MINDSTORMS NXT/EV3, connect a Wii Nun-Chuck to the adapter, and you can control your robot with the Wii Nun-Chuck! The NXTChuck allows you to use the Nun-Chuck™’s trigger buttons, joystick, and motion-sensing controls. What more do you need?

The adapter works with the official Wii Nun-Chuck, and with the couple of eBay acquired clones I have. Therefore I think it’s safe to say that if it works with your Wii, it will be fine with the Nun-Chuck Adapter.

Step 2: Construction

As can be seen from the images and video above, the whole robot assembly is pretty straightforward, and thus to easy to repair if needed in a hurry. I have made a LEGO Digital Designer CAD file and the RobotC code available for download at LegoMindstormsRobots.com.

The Rotacaster Robot-wheel at the Robot's rear allows for easy and smooth motion in any direction. The omni-wheel also saves building, the ever unreliable jockey-wheel.

I'm very glad I took the idea of turning Rotacaster Rollers into Robot Wheels too Peter McKinnon. As I result I thoroughly enjoyed the development side of the journey.

Honestly, I really don't know how I survived without a Barrow-load of Rotacasters in my LEGO Toolkit.

My Killough Platforms are a real head-turner at the LEGO Shows. I like studying the expressions on peoples faces as the try and workout how they in fact move.

cheers
