Here is a pic of our bot hanging from the bar, on the first try might I add!
here it is, the first look at team 174’s SnoBot. This is the first time we got it to hang, it was the first try and it was unassisted!
it doesn’t look like it’s off the ground. you should get a clearer pic… congrads! it feels great doesn’t it
Have you had any problems with 4-wheeel drive with those tires? I saw several systems at the DC scrimmage earlier today with similar drive set-ups, that were learning to “dance” as the high-friction tires tried to scrub sideways on the carpet while doing point turns. Teams were learning very quickly that the tires behave VERY differently on carpet vs. hard floors, as they were seeing a real competition environment for the first time. Have you had a similar experience?

yes actualy, but we are preared for that. We have a set of casters on some pnumatic cylinders that we put down when were on the carpet for better turning. When we climb we go into awd mode, and when we go up those larger steps they assist the back end in getting up.
sorry about the quality of this one, but its the only pic I could find where you could clearly see the bot in its 2wd mode http://www.chiefdelphi.com/pics/bin/107748317912.jpg
Yep, we’re using the same wheels and had the same problem and came up with a similar solution. There are times when high traction is great and others where it really hurts you.
