Lunabotics Worm

My lunabot was designed like a worm so it can eat the regolith and filter out the non-regolith dirt, and then it can wiggle its way back to the moon base. It is powered by nuclear energy so that the power doesn't have to be changed in about 30-40 years. In its body it contains two parts, the filtering which when the regolith is fully filtered and then it will be transferred to the storage. When it gets back to the base it will throw up the regolith into the storage in the base. Then it will go back and repeat the process. It is made of tungsten, the strongest metal in the world. It has a brain of its own, it will navigate its way through the moon while mining, it will squish itself together to prevent damaging its navigation system when it is crashing into the moon.
