I actually built this VGTV a few months ago, but was unable to publish it until now. A VGTV (Variable Geometry Tracked Vehical) is basically a tank that can change the shape of it's treads! By using a linear actuator, I can lift the front of the tracks up to 90 degrees with an infinite amount of points in between! The trcks are driven by 1 M-motor each with direct drive. A third M-motor drives a torque limiter gear, wich drives the linear actuator. By changing the shape of the treads, the tank can drive over many diffrent terrains and obsticals. Thanks for reading, and don't forget to comment!
