Triangle Tank

pinshape

Human: Summary Another little tracked robot, inspired by Ktronics and Geir. You'll need to print six wheels, two sprockets, and two sideplates for the basic assembly, plus two battery mounts and one Arduino/Nano holder if you choose to use them. Purchased items include motors, belts, threaded rods, bearings, a battery, and electronics. Some early versions of this tank had issues with belts running off wheels and jamming motors, but the little flanges on wheels and sprockets seem to have fixed that problem. You could put additional plates on the outside of wheels like in the "one_side_assembly" .stl file, but my current version works okay with just the inboard plates as shown in the photo. BILL OF MATERIALS: This thing uses two geared motors and 94-tooth timing belts for tracks. The battery is a 12V Li-ion which is probably overkill since these motors are designed to run on 3 to 6 volts. It really scoots, though! You could probably run it on six AA batteries and save a few bucks. The axles are six-inch, five-sixteenth threaded rods bought at Lowe's. You could use eight-millimeter rod without modification to the design if you're in a place where metric is more common than it is here in Texas. The wheels use eight-millimeter skateboard bearings. I've mounted an Arduino Nano and a L9110 H-bridge. The arduino holder is adapted from cimo's customizable thing. I plan to put an array of ultrasonic sensors on it to make it autonomous, but I haven't gotten that far yet.
