Some description about the robot-

Drivetrain:
4 wheels - 8" standard FIRST rubber wheels.
4 CIM motors.
1 Encoder on each side.

Intake:
Catches balls from both the front and the rear end of the robot.
A single roller in each side makes the initial catching of the balls (Each connected to a RS-550 Banebot motor geared down by a 4:1 gearbox).
A set of rollers connected by belts rolls the ball into the middle of the robot, where it is lifted up by a raised roller and the opposing direction the rear and front rollers are spinning (All rollers are powered by a single AndyMark gearmotor).
A pair of conveyor belts pulls the ball up all the way to the shooter (The belts are powered by a FisherPrice motor geared by the FisherPrice gearbox).
The system uses 3 distance sensors to determine how many balls are in and to arrange them in fixed distances.

Turret:
A window motor connected to a 30 degree arch which gives a range of 15 degrees in each direction is automatically directed by the camera before every shot (corrects itself automatically using the drivetrain if the angle is off by too much).

Shooter:
A single custom built wheel is powered by two RS-775 Banebots using a custom gearbox.
The camera detects the distance from the alliance wall by the reflection of the reflectors, then using an encoder (which is mounted on the wheel's axis) it sets and corrects the speed of the wheel to get an accurate shooting distance.
Can shoot from a distance of up to approximately 40 feet and is fairly accurate from up to 30 feet.
Can also shoot from various angles with ease.

Bridge Manipulator:
A flat plate pushes the bridge down using an AndyMark gearmotor.
It has 3 positions which are set using 3 micro switches (Automatically pushes down when in contact with the bridge).
Blocks up one third of the back side to allow intake of balls off the bridge while preventing it from catching too many balls or getting the balls stuck.

Good luck to all teams.
