Project TITAS Tiny Tank with Suspension Technical data: Length - 166mm Height - 97mm Ground clearance - 24mm Unladen weight - 515 grams with two 18650 batteries and electronics. Full magnetic suspension Design speed - 0.37 m/s at 6V Interchangeable top allows you to install your own equipment, such as sonar, camera, multiple rocket launcher, or mid-range cruising missile (Important: Not suited for long-range missiles). To assemble the tracks, I used 0.9mm piano wire cut into 20mm pieces. If you don't have piano wire (available at RC shops), you can use paper clips. To prevent track pins from falling out, fill holes with something (I used liquid nails). Bearings must fit tightly in their holes; if they're too small for you, post a comment. Two versions of BodyBottom are included. One is designed for installation of an Arduino nano, and the other (BodyBottomBlank) can be used for anything else. Optional 5x3 and 3x5 magnets allow fine suspension tuning.
