Holy Wii Batman!
 
Here is a robot project we are working with Intel and ASU to develop. It will eventually be a roaming autonomous robot.

The student was working on code during the break

That is really cool!

How were you able to get communication from the Wii Remote?

Wow, that really is cool. Mecanum wheels are always great.

@nighterfighter: There are ways to interface NI hardware/software with the Wii, a couple of people have done it. Most notably this guy:
http://decibel.ni.com/content/docs/DOC-2326

The Wii sends out a Bluetooth signal, so if you can sense that and figure it out, you're good to go. I'm sure there's a whole slew of resources out there for people who want to do so.

We actually did not use any FIRST hardware. We used Phidget Motor Speed Controllers - http://www.phidgets.com/products.php...roduct_id=1064 - and yeah they can only do 10amps continuous...

But they are really cool in sense that they connect to a regular computer via USB. and the code is really intuitive looks like this -

Code:
                if (ws.ButtonState.Two == true)
                {
                    leftmotorcontrol.motors[0].Velocity = -100 * (ws.AccelState.Values.X - ws.AccelState.Values.Y + turn); // front left
                    leftmotorcontrol.motors[1].Velocity = -100 * (ws.AccelState.Values.X + ws.AccelState.Values.Y + turn); // rear left
                    rightmotorcontrol.motors[0].Velocity = 100 *(ws.AccelState.Values.X + ws.AccelState.Values.Y - turn); // front right
                    rightmotorcontrol.motors[1].Velocity = 100 * (ws.AccelState.Values.X - ws.AccelState.Values.Y - turn); // rear right
                }
                else
                {
                    leftmotor.motors[0].Velocity = 0.00;
                    leftmotor.motors[1].Velocity = 0.00;
                    rightmotor.motors[0].Velocity = 0.00;
                    rightmotor.motors[1].Velocity = 0.00;
                }
This is the heart of the mechnaum drive system, kinda simple... Just adding up all the victors...

As for the Wiimote I used the wiimotelib. Here is some nice open scr code and a the dll download - http://www.codeplex.com/WiimoteLib

I did all the coding in C# using Microsoft C# IDE...

The little black box on top of the bot is a fitpc2 - http://fit-pc2.com/wiki/index.php?title=Main_Page, yet another very nice piece of hardware

And to top it all off the entire bot with Ultra sonic sensor a Digital/Analog IO board, motor speed controllers, frame/wheel/hardware, and cpu was under 2k,a very attractive price in my opinion.


Extra info -----

Auto Programming and better video coming soon...

Here is our wheel config -
