Re: Mounting the arm

To mount an arm:

Build your robot so you have a plate about 4.5' in the air. Put a brass plain bearing in it. Also put a bearing directly below, around where your motors are. Buy a 5' section of thinwalled steel 1" pipe, put it through the bearings, weld a segment of 5/8" shaft to the top, put bearings on that, and your arm on the bearings. Put a sprocket on the lower part of the steel pipe, drive it with a motor to give yourselves a turret. Fix a sporcket to the welded 5/8" shaft on top, put a gearbox on the arm, chain it to the sprocket.

And your done. Maybe add another segment or two after the first one for a really cool arm.
