Our shooter does not aim. No, I am not being dumb, we really do have a shooter and it really does not aim.

I think that this year the success rate of teams using the camera will be MUCH higher than last - the illuminated, elevated target really works wonders.

Still, you better alot the better part of a week to program the thing and tune all your feedback systems if you want it to work (especially if you're using empirical look-up-table data, which is the simplest way).

Our planned course of action is to be aiming with the camera, but instead of messing with equations, doing just that, working with a lookup table and simply testing, testing, testing to get the values needed. After the camera positions the turret, operator will manually fire. As a backup, though, we will have the option for the robot operator to manually aim via atari (subject to be replaced with other) joystick and have some sort of sensor feedback (still undecided) on the dashboard to help give the op a better idea of where it's aimed.

Although we still lack a robot to begin getting values for the table. :rolleyes:

That is 100% exactly our plan as well ^
Cept we plan to calculate a base set of values for our lookup table and tweak as nessicary. As for where we're both going to find an atari paddle, we're not there yet.
:D

If you asked me, this sounds as if you are going to get really close to the goal, i.e. on the ramp, and simply shoot from such close a range that there is no need to aim.

or they shoot so many balls at a time or rapidly that they can hope the majority goes in or that the operator can compensate for each missed shot.

we also determined that a lookup table based on camera tilt angle would be the easiest method
