Walking around all poles to the goal has already been excluded
in the rules for 2007. See 19.1.:
"The robot must reach the goal, enter in it,
by crossing at least once the line between two obstacles and by avoiding
touching all obstacles."

Larger robots can walk faster with larger steps than smaller robots.

Robot specific distances make not much sense.
I suggest to keep it in the suggested way because it is not easier
than the obstacle challenge in 2007 where only a fraction
of the teams could manage it.
With best regards,
