lunar rover speedy

My robot will scoop lunar dust from the front and move it to the back where it will heat up the lunar dust to 600c which will extract the helium three from the lunar dust. Once He3 is pumped into Helium tanks, the regolith will be put back into its original extraction point. My robot will carry less dirt and take more trips.I think this is better so the lunar dust has more time to heat up. It will have a cover on the robot parts but not the scooper so it can scoop it into the furnace. I think this will work because if it sticks to the cover the rest will go into the furnace.
