pic: 6 wheel drive with a suspension

You may be correct, but from what I have observed from the ball differential it should work. The omni wheels will be attached to the shaft that is attached to the disc holding the balls. The balls will be pressed on each side by the sprockets. If the sprockets are going the same direction than the wheels must be moving the same speed. If the sprockets are going in opposite directions (equal full speed) than the omni should be stationary. Correct? Now if one sprocket is not moving while the other is moving at full speed than the omni wheel should be moving one direction at half speed. Thus allowing for a 45% angle run of the robot. Any other difference should be also of the same ratio. On paper the ratios work out but in practice I may be wrong. We will be building a test system this fall to find out.

I don't really understand where the suspended part is. Coudl someone explain it for me?

Go to our site http://www.team1322.org/ideas.htm and scrol down to see a drawing of the suspention movement. The robot will be attached (with a pivot) to the drives in two places center of each moving drive.

Ohh, I see. Thanks.

That's seems like a very logical and feasible idea.
