Our team (1177) went through this analysis and decision making process today. We eventually created a decision matrix listing our options which ranged from 2 wheeled, 2 motor drive up to multi-wheel/tread and multi-motor drive. We ended up deciding to use wheels and multiple motors in a 4 wheel drive configuration for a combination of reasons.

The main reason is as stated in the replies thus far. Treads are great for traction, however that traction comes at a price which is increased power draw. Along with that power hungry traction system, your speed/current ratio is lower. We resisted the urge this year to use treads, and will utilize the 4 wheel drive.

1) what are the pros and cons of tank tracks?
-we know that we'll gain torque
-we'll be able to make it up the step
-we think we won't loose much speed

2) Can we buy premade tank tracks? If so, from where and how much?

3) How do we make tank tracks?

4) How long does it take to build the tracks

5) Any words or advice or experieces would be greatly appreciated.
