I noticed that performance on carpet is quite poor, due to the thin wheels. I designed some alternative wheels, more rover-like, that are designed to provide a greater contact patch, and include ridges to improve traction.
Here are the wheels and some pictures:
To be honest, the performance improvement was marginal. I may need to change the design to increase the contact area further, and make the ridges a zigzag pattern. I also want to add a groove for a rubber o-ring to act as a tire on smooth surfaces. This rover wheel is quite noisy on hard floors.
Any thoughts?

Re: Alternative wheels for Spirit Rover
Love it.. Too bad we could not make these 2 or 3 inches in diameter to give better surface area but then we would have to re-do motor mounts and such.
Ultimately I want to drive the Spirit Rover around my house remotely so I may have to design up a bigger system to have bigger wheels, hold more batteries, motors, etc..
On the other hand maybe I should just take my dead WowWee's Rovio and convert it.

Research is the only place in a company where you can continually have failures and still keep your job.
