Can anybody tell me what "but no turning on the spot" means in the statement of problem 208?
Does it mean that a path cannot include a series of 5 clockwise circular arcs or a series of 5 anticlockwise circular arcs?

It means there are no sharp angle. Direction changes smoothly from one arc to the next.

it's a very nice problem.
One point of clarification: the robot cannot reverse.
Namely, there are no paths of length 2.
This took me a minor amount of time to work out.
Just putting here in case someone also thinks the robots can reverse.
