Little toy

My Lunabot has a scoop that is attached to a vacuum hose that will transfer the lunar regolith to a bucket in the back of the robot. The bucket has a weight sensor under it so when the bucket is full it will tell the robot to go back to home base and drop the lunar regolith off. The Lunabot will also have a anti-dust outer layer covering the hoal Lunabot so the dust doesn't affect it. The Luna bot will be 3.5x2x2 feet. The Lunabot will run on rechargeable batteries. When the batteries start to die the light in the front of the Lunabot will start to flash red to indicate that it is about to die and needs new batteries. To replace the batteries you open the door on the undercarriage of the Lunabot then simply pop out the old one and put the new ones in.
