Re: Shooter Precision poll

Our system uses the camera to determine distance, and from there uses a lookup table to set an appropriate speed (we are measuring wheel speed using a banner sensor to account for battery voltage depletion; if this doesn't get finished we'll just swap to use pwms and hope we don't mess up too much). It also uses the camera to line up the rotator accordingly. In addition, there is a manual mode should the camera brake, which allows the 2nd driver to rotate the shooter using a joystick and change the speed using a set of 4 buttons (the speed he is setting will be displayed by the user byte on the OI).
