Incidently, the duck has to be worth double the number of points available for collecting all the other blocks otherwise no-one will bother.
I have a couple of doodles which i will scan in at a later date.
We pretty much guage the size of the robots according to the gap, so we say it cant be bigger than 0.5 cube but then say the gap is 0.3m high, we wont get stupid sized robots.
I like the ramp because of the number of potential completion ways, a ramp isnt that hard to build, it'll look good and it poses less potential damage to robots (and thus the floor and producing shit that we have to clear up).
Thoughts?
