I know that. That's why I'm describing the process of adapting the Chicklet to mate with the three-pin headers on the RC.

Ah, OK. The fun begins...Now, how do you power the Chicklet on the robot? Direct connection to the 7.2V battery, or will a three-pin header tranmit enough power?

The Chicklet claims to draw no more than 500mA. The camera had no trouble with drawing 235mA from the PWM headers... I'm no EE, but I'd expect that the Chicklet would be okay, too.

Well, thanks for your help guys. Actually, if I were doing the mouse idea I would just take a ps/2 mouse and strip it down to D+, +, and -. Then I'd plug that directly in the RC. But, as it turns out, I can't seem to find mice that operate faster than around 20 inches/second. Since our robot will be going feet/second, the mouse wouldn't be able to keep up. There's also not enough room on the bottom to mount it higher and widen its camera angle nor can we do that with the ceiling on account of the rack. So it looks like I'm stuck with a gyro, accelerometer, and gear tooth/optical encoder combo using a line sensor for recalibration with the alliance lines.
