After the semi successful trial with the skid on front of the Robot
I have concluded that if it is used in combination with castors it
might just solve our steering problems.
A built up front spike is needed anyway to feed the enemy into the scoop
as at the moment the scoop rides an inch or so above the surface
Also I just received from e bay a new pair of bearings for the wheels
which I intend to make adjustable and thus make both wheels touch
the floor evenly -this should also help with the steering if I can achieve
the same level on either side
