"The Tank" started several years ago with a cardboard and duct-tape spaceship out of cardboard boxes. The first ship was simple. The second ship had double thick walls for stability. The third ship was a two-story monster with a hundred dollars of duct-tape. The fourth ship was built with a wooden frame and go-kart wheels to be rolled around the yard. My ultimate dream is to put a high torque, low RPM motor to slowly creep around the yard.
