HOG Drive - Hemispherical Omnidirectional Gimbaled Drive

Discover my latest designs and progress at Marginally Clever! Check out the video showcasing my invention, which was also featured on Hackaday. Recently, I found out that this design is highly effective for vector thrust on an RC kite. This design dates back to 1938, with Curtis Boirum's version even making it to Hackaday. Now, you can access the blueprints to build your own model! Use one of these models to create a remarkable RC car, or use two for a car that moves in any direction. I'm currently using this design to construct a line-following robot with approximately 15 degrees of movement on either axis. If you decide to use my design, please share your creations with me so I can inspire others as well! Note: I am still refining the model, and it requires a few more holes for proper assembly. You will need two hobby servos, one Tamiya 70171 kit (cut to size), a pair of single-arm servo horns (or a single double-arm horn), three 10mm M3 screws, a pair of zip ties, and a 5v0.2a DC motor. Assemble as shown in the pictures, and be prepared for some filing due to tight fits. I'm still figuring out the best way to attach the hemisphere; any suggestions are welcome. The vehicle's body will consist of folded cardboard with two free-spinning wheels at the back. I'm using QRD1114 IR sensors for line detection and an Arduino for the brainwork.
