Re: 6 Wheel Drive vs. 8 Wheel Drive

We had a lot of traction and pushing power with the 8WD though, which was useful for the balancing.
Hi Grant,
You said a lot there, but also not a lot.

You described what configuration you chose, and what challenges you hoped it would overcome. Can you explain what specifically about your chosen configuration you thought would lend itself to overcoming those challenges? Do you have anymore insight into your process which lead to this decision? Was there prototyping involved - CAD or otherwise?

Can you explain why you think 6WD has superior maneuverability?

What characteristics of your drive do you think lended themselves to high traction and high pushing power (which are related)?

-John
