For instance, an unsupported shaft can have extreme friction in turns that does not exist in straight driving.
What ever happened to this poor robot?

I have a sad image in my mind of this little guy going back and forth over the bumps and back again but never turning, never facing the goal or the tower... back... and forth... back... and forth...

Give us an update please.
