Visual Lego & Microsoft Robotics Studio September CTP
I have been too busy lately to play as much with my Lego Mindstorms NXT as I had hoped. I constructed the TriBot and got it to do the basic tricks; wait for the ball to be dropped, drive forward, pick it up, turn around an drive back until it crossed the line etc. But the Lego NXT kit has a lot more to offer and the latest September CTP of Microsoft Robotics Studio shows some of the things you can do with it and other robot kits. The "Tutorial for Using MSN Live Messenger to Control a Robot" looks particularly neat:
You can download the September CTP here.
Visual Lego, on the other hand, takes a different approach. Instead of providing a "virtualization layer" for a lot of different bot hardware it is targeted squarely at the LegoNXT. It keeps the API as well as the operations a lot simpler. No need to run a .NET "host" program on the Lego brick, just turn on the NXT and run.
