Towards the middle even... compromise between frontal positioning and weight distribution at least.

Not quite as good as the front as there claw isnt straight on the opponent when you turn. Thats why Razer had omnidrive wheels at the back so it turned about the front where the claw is.

Hi Ed
Well I will be doing 2 protos out of wood first one like it is and I will do the other with the wheels to the front thanks for the advice. Dont think I will try the middle as I want to keep the T shape as I already have a T piece for the base.

Razer of course had the rear wheels so that power reached the ground at the back also while going in a straight line, hence good weight distribution. Compromises compromises

Lets agree to disagree

It is worth mentioning that another reason for Razers wheel design was to get over ramps - The crusher would come down, pushing the lever for the 5th wheel to the floor. Leaving Razer with a high ground clearance and the rear wheels to power it forward.

Built a test bed for the claw to get all the measurments for the pivot points before I start to cut the Ali for the base. The base will have 2 groves cut the full length of the base the uprights will be bolted and then welded into the groves hopefully this will stop the base from bending.
