SHLT - Stick Bug

grabcad

The SHLT (Super Heavy Logistics Transport) idea for the Moon and Mars called "Stick Bug" uses 12 MLW (Michelin Lunar Wheel) and shortened limbs from the ATHLETE robot. The suspension limbs and wheels are not my design! These components already exist. They were used to speed up the eventual production of the rover. We need 4 "Stick Bugs" to carry the Common Habitat and they approach the lying Common Habitat from the sides to lift it. The catching limb hugs the rim and clamps down. By shortening the limbs and using 7075-T6 aluminum, 1 "Stick Bug" weighs about 5,000 kg. As of now, the dimensions of the folded one are as follows: Length: 4780mm, Width: 2580mm, Height: 1850mm. In further development, the Common Habitat's catching limb can be hidden more, so it could be more compact when folded. The Common Habitat's lifting limb could also be replaced with another that could perform other functions. The shortened limbs from the ATHLETE are able to unfold to a height of 1750mm, and the frame lifted by electric actuators rises to a height of about 2750mm, which together gives us a height of about 4500mm. The rover is capable of negotiating a slope of at least 20 degrees. The pressure of one wheel from total transport on the Martian surface would have values close to 14 N/cm^2 that is 0.14 MPa.
