Space Claw

My robot will pick up the moon dirt with a claw kind of like something you would see on a claw machine. My robot will be able to carry a lot at a time so it will have to do less trips. For the mon dirt since it clings onto things very easy I would make the claw for my robot mental because I feel like things are harder to stick to metal but if their was moon dirt still on it I would have a little brush attached to the claw so it can dust the extra moon dirt off that wouldn't come off.
