I should check the search page for posts about 703 more often, but alas at least I'm only a few days late.

I heard someone was looking for info on powerful drive trains? I'd be happy to answer some questions if there are still any about our drive systems (I noticed a few a page or so up)

Yep, 703 was great at pushing in 2007. They had an incredible defensive machine. Yet... I bet that NO ONE made any quantitative measurement of it's performance. Here is what I would looooooooove to see:

• Step 1 - Measure it's linear pulling force while on carpet (use a fish-scale).
• Step 2 - Remove all but the 4 outer wheels.
• Step 3 - Throw the extra wheels on top of the frame, so the overall robot weight doesn't change.
• Step 4 - Measure it's linear pulling force again, while on carpet.

I speculate that these numbers will be extremely similar. Within 5%.
Maybe I'm wrong. I would love to be wrong. I would LOVE for someone to prove me wrong with some solid engineering analysis beyond the usual "703 pushed really hard, they pushed against truck town and everyone knows that nobody pushes truck town..."

That could be very easily arranged if you're still interested, we've still got that bot laying around and (for the most part) working.
