Re: Spiral Drive
 

well i was thinking that you could get like 2" ABS or PVC and then wrap the treads from the Plaction wheels from andy mark in a spiral thus not violating any rule about damage to field or metal contact with the ground

also if you had 4 of them i think that then it would have the ability to turn like a tank and move horizontally like omni wheels

please correct me if im wrong

Re: Spiral Drive
 

Correct on not violating a rule (unless unforeseen results happen).

Correct on turning like a tank.

However, moving sideways will be horribly inefficient, due to the amount of traction generated by the treads. You may even get enough to destroy the treads, or break them loose from their attachments. At that point, consider mecanum or omni wheels, as either will allow you to go sideways.

Re: Spiral Drive
 

The problem with this idea is that the spiral works by having the ribs slide easily over the surface, and the conveyor belt treads like that do not slide on carpet at all. And the rules seem to prohibit any type of thing that would, as it would likely be considered to be a "cleat".

Re: Spiral Drive
 

I would envision this could be made legal using specific materials. The other factors I also considered is the space in which you have to work and the power of the motors available. 29 x 36 is a small footprint in which to add four of these devices. You also will not be able to climb very well without having the center line of the screw be fairly high. I am guessing with all the limitations, a screw could not be made to climb the bump due to the size and power needed.
