Re: how important is ground clearance?
Our particular ground clearence (.8670 inches) had more to do with our drive train design than with anything else, still, it gives us an excellent wheel base. Currently, we can have a tetra on our arm, fully extended to cap the tall tetra, and our center of mass is only a couple inches off the ground. Our design is not good for entering the big tetras, but we can have our arm fully extended, and are still virtually untippable.
On a side note. If you have a good animator, you can set up reactor (the physics engine in 3DS Max) with a properly weighted and dimensioned robot, and then do testing with read out about various stresses. This actually saved us from a claw design that although spiffy, was prone to failure at certain angels (i.e., we input the torque from one of the motors, and discovered that in certain situations we could not rotate all of the way)
