Re: How does your auto-aim work?

accuracy could increase with two cameras if you have a problem with it tracking through a few pwm positions in the tilt of the camera. If your out by center field, that makes a big difference in calculations, so you could use the average angle from both cameras to get a better reading, but it would be more efficient to just take the numbers from two loops and average.

For our bot, we had an auto-aim that was working perfectly, but when you get to competitions and the bright lights drown out the targets, its a lot more unreliable. 220 confidence to 20 more unreliable. It also is a pretty large target, but if your shooting from further away, its nice to have auto-aim.

We had a tilt and pan motors, each powered by relays, the pan was just a number based on the servo position of our camera it drove until the pot had the same number (after conversion, the pot was 16-bit). Same with the tilt, based on the distance to the wall, we found an angle, which was converted to a postition on the pot, and driven to it, as long as it was within the limits.

Thats about it, not overly complex, and with these large nets, aiming is pretty forgiving.
