The current plan:

For aiming we are hoping to have a "slow poke" mode. Basically the driver presses a button on the driver station and that slows the drive motors way down so that she can agle the bot correctly. We want to couple this with the camera...piece of polycarbonate with some markings on it...line the markings up with the backboard and bobs your unckle. Finally would be speed...Two ideas on this.

Simple is we use the markings on the polycarb to guage distance, and then use a shaft encoder to set the speed of our spining wheels based on the distance

Harder...We use an ultrasonic sensor to "measure the distance to the wall, have an adjustable hood, and use computer vision to align the shot using the "slowpoke" mode.

Probably some combination of the two. We have the basics down in turs of programming...

For dumping, we want have the camera swivel 180 degrees, and drive backwards. We would possibly follow the red or blue line down the sides of the key and then squidge over at the burm.

We'll try to get the cad files up by sunday night.
