oh no. we actually get air after hitting a piece of wood during a wheelie. VERY cool.. only makesure the landing area is clear of small balls. we kinda did a flip after we landed

on our design, we just wont be able to do it with just one caster. at the least we're going to need to use two. inlign for and back.
as in

can't give out any more secrets...
but anyways, we might look into teflon or delrin.
but IS there a very easy way to make an omniwheel?
cheap and lightweight. it can be small. or actually, small is better.
we have a CNC mill, but its not exactly the fastest thing around.
will making one out of aluminum be too weak to support a robot?
