this bot will slurp up the dirt into a container so when it is sent back to earth the scientist will look inside the container to get the soil. Also, it has a tire that if the thing flips over it can still move also it has Saft ni-cd battery for long life. Also, it has an engine just in case the battery dies. also, it slurps 5 pieces of dirt a second. when the container fils it will become a rocket which will be sent back to NASA so they can look at the dirt and do samples
