Hi,
I'm writting a PC based application which allows user to remotely operate the Lego NXT and PIC based devices over RS-232/485, 802.11, TCP/IP and Bluetooth. Basically, you drag gauges, buttons, knobs and sliders onto a Dashboard surface and link them to the robot's registers.
There is a default dashboard for the Lego NXT Tri-bot, and also some PIC Sample C code for MPLAB. It am looking for more 'advanced' users to try it out, and there is a free version for download at

If you do use it, just send me some feedback good or bad
Cheers,
Lou
