Nice effective chassis. *adds another mark under the 6 wheel drive category
Very nice. How much does it weigh? Also, do you plan to tension those chains?
Thanks for the compliments everyone. Our frame weighs a little more than 12 pounds and we bought idlers for tensioning.
Whats the ground clearance on it?
Looks very similar to our design so far. 'Cept we have a few more bars going across and stuff. 
What’s with those circles sitcking out around the axle’s on the outside?
The clearance on our frame is about 1 inch but we have more pieces to be added on to make it even lower. The circles are shaft collars which keep our shafts from sliding out. They are durable enough to survive an impact from another robot but we may still place them inside our frame.
