Re: Is the suggested Vision Camera setup ILLEGAL?!

Has anyone tried this to see if it's possible?
It is possible, and it DOES move when the robot is disabled. No hacking is necessary, as this behaviour was observed using the supplied Frc_CMUCam2_rev-3.zip code package on the IFI website.

To recreate:
1) Disable OI with competition port dongle
2) Power on robot
3) Select desired colour by pressing Trigger on Joystick 2

Watch camera servo move and track your colour while the robot is disabled.

Interestingly enough, this turned out to be "a feature, not a bug" during camera setup. It was nice knowing your robot wasn't going to bolt on you, yet you could see if your camera was calibrated/configured properly by watching it move.
