We created a menu system which made configuring the robot like using a copy machine. You could use up and down buttons to change the menu options, and select/back to advance through the sub menus.

The real glory in our system was in the pocket PC based waypoint creator. Make the waypoints on the PPC, plug in the serial cable, and it automatically synced. Cool stuff.
Didn't use a camera last year?
We were looking at using TTL port for simplicity in hardware (no level shifters) but we want to include a passthrough to make the camera an option alongside the black box.

I'm a FIRST relic of sorts, I remember when we used PBASIC and we got CH Flightsticks in the KoP. In my day we didn't have motorized carts, we pushed our robots uphill, both ways! (Houston 2003!)
