This is my robot I built I had a partner named Jaxon. He never showed up on our final day but it was fine because I was the designer of it all. The whole point of our robot was to pick up some Moon regolith ( Sand ) from the ground. Incase your wondering Moon regolith is made of

1. Broken up rocks

2. Grains and minerals

3. Glass particles

These are just the bare minimum for it contains other things as well. Moon Regolith is seen on the Moon's surface like sand or dirt but on the moon.
