Claw-Machine Inspired Robot

This machine has a trap door that opens and lets out a claw-machine-like arm to grab regolith and deposit it into some containers inside the hull. The wheels are spikes, which means they dig in and keep the robot locked in place no matter what. It would be about the size of Perseverance and would be able to carry quite a bit of regolith. It would get past the static-dust problem by being coated in a layer of ice. Basically, they would cover it in water, then expose it to the outside, and let it freeze. Then, when it comes back in, the ice could be taken off or melted maybe. The arm would be very articulated and similar to the one on the ISS.
