YouTube video of screw drive tanks in action indoors on carpet. https://youtu.be/BrmW2oacwbM Video of tanks in snow. https://youtu.be/7Ska6xW8SLM The screw drive units are a remix of thing 2317805 Build pictures and info can be found on Alphadrome website in 3d printed section or this link "until the site moves things around". http://alphadrome.net/forums/topic/23063-archimedes-explorer-screw-drive-3d-printed-robot-tank/ I use standard TT gear motors to drive screw units. I also used a RC toy from Walmart to control gearmotors. The battery box area will hold a 4 AA battery "dual in line" pack. I did two different bodies for my build but I think if I give you just the base for body then you can have the fun of designing your own body style. Print 2 of screw drive A parts and 2 of screw drive B parts. Use part A parts for left side and part B for right side, lets say, it does not matter as long as part A screw drive parts are on same side.
