scruffys still worked after GSL just the scoop got bent and the body had some chew marks,so if you made your bot from 10-15mm t6/t7 aluminium bolted together and got a piece of 5mm hardox to bolt on the front as the blade for your scoop then it should withstand a good bit of punishment

the normal cheap aluminium on ebay wont last long

were you aiming to build something like mr pink
