Servo Tank

thingiverse

My take on a servo tank. Used relatively inexpensive components. MG996R servos, Henglong 1/16 Scale Tiger Tank tracks and 4xAA battery holder from Amazon. Links listed below. The servos will have to be modified for 360 degree rotation. There are plenty of videos online on how to do this. Runs on 4AA's. Wiring should be straight forward. Make sure receiver can handle 6.0V. Added a switch I had lying around to power on and off externally. Used a standard 2.4GHz receiver using elevon mixing for directional control. Unsure of hardware I ended up using but can figure out if need be. I had side plates cut from 0.125" aluminum plate but don't see why 3D printing these wouldn't work as long as 100% infill is used. I'd use a solid front axle if you opt to 3D print. Might have to get creative with battery holder location with solid axle as passes through same location. Made drive sprockets to accept the round servo horn supplied with servos and used servo mounting screws to secure. I hot glued them on first and adjusted to run true before hot glue cooled then screwed them to sprocket. May add attachments in the future to turn into any number of tracked vehicles such as bulldozers or track hoe/excavators. With tracks listed and other components, should have enough to make 2 tanks. May have to match servos to find 2 that run about the same speed so tank runs straight.
