They allow for a maximum weight of 40kg on the bot . . . thats a lot! And in a 4m x 4m sandbox and 30 minutes time alotment Im wondering if thats enough dirt for 5 minutes for a good design. Id use something much more powerful than a servo.
I was thinking of a tracked skid steered robot. This would allow point-turning abilities and also keep the total weight down as 2 motors/gearboxes+rubber tracks weighs less than 4 Motors and 4 wheels. (the rubber tracks are completely non space relevant but the rules allow for non space materials and mechanisms (per rule 1.5g)).
This isnt actually true . . . But I dont want to offer any ideas yet so no one gets locked into my track of thought. The out of the box ideas are always the best, just hard to come up with . . .
PGH and DC are a close enough drive.
I think we could find companies who would be willing to sponsor some of the work.
Ok, lets wait until they make the next announcement for the next event. In the mean time Ill think up various ideas.
What is the density of regolith, anyway? (to calculate weight)
