Done CADing

This is almost the whole thing.
The far wheels are the driving wheels, each with their own servo.
The other wheels are casters
The big thing on the right is the the vacuum pump.
At the end of the arm is the vacuum cup, and the ball sensor rods.
In the center is where the balls go.
The rectangle in the lower right corner is the board.
The only things missing are the sensors (IR, bump, CDS).

Robot Description

This robot, once sat upon a pool table, will navigate its way along the walls of the table, stopping at each pocket and retrieving the balls. It has a robotic arm with 4 degrees of freedom, that has a vacuum cup on the end, along with a specialized array of bump sensors. This arm will retrieve the balls and will place them on an identification stand, where the balls will be identified and then placed in their proper racking position within the robot, by the arm.
