I designed the frame to house two separate motors, each controlling speed and direction, to steer and drive the wheels independently from others. Instead, I implemented a 4 Wheel Independent Steering/Driving (4WIS/D) system: a steering system for a four-wheeled vehicle that allows for separate speed and direction controls for each wheel.Īfter an initial sketch of the wheel's frame, I modeled the same design in Fusion 360. Unfortunately, I was a bit under-qualified to suspend wheels in mid-air with electromagnets, as many sci-fi movies suggested. You can also check out this maker portfolio video I made for my college application or checkout the github repo containing the full code.Īs I mentioned above, ORBITRON is a vehicle with spherical wheels, hence the name 'ORB'itron. Then, I'll introduce you to the highlight: a clever algorithm I built to control Orbitron seamlessly.
This article will showcase my vehicle prototype Orbitron along with a short story behind the building scene. Developing an intuitive control algorithm for 4WIS/D vehicle in Mathematica.Building a vehicle with spherical wheels that implement a 4 wheel independent steering/driving (4WIS/D) system using Arduino.Now, this project consisted of two major goals upon start: Being a heavy Sci-fi fan myself, I always wondered: how would those spherical wheels from Tron and I-Robot work in real life? And this simple thought began the 6-month journey of Project Orbitron.
