We were able to tap into our available TTL serial port on the RC last year to drive a serial-driven LCD. It was a 4x20 character display, and was very useful for diagnostics and PID loop tuning. We could test the robot and use the screen as a pseudo terminal to test functions of the robot without a laptop.
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.
