Tightrope-walking powered Gyroscope

Update (4/29/2023) - below is a link to the STL files for recreating this project: :5998400/files In this video I’ll show how i made a powered gyroscope that can travel along a monorail or tightrope. I’ll explain how angular momentum keeps the gyro upright, even when gravity or other external forces try to knock it over. The gyro uses an 8“ diameter flywheel printed with PLA, with 21 1/2“ steel bolts around the edge to dramatically increase the moment of inertia. Some performance figures: Motor KV: 620 Motor Voltage: ~15V Motor Speed: ~9,000 RPM Flywheel Speed: ~3,000 RPM Flywheel moment of inertia: kg*m^2 Flywheel kinetic energy: 680 J Flywheel angular momentum: 4.3 kg-m^2/sec Drive motor speed: ~120 RPM The drive motor has plenty of torque to climb a steep incline, but traction is a major limiting factor, so the best i could manage was 10-15 degrees on a tightrope. In the future, I’d like to build a rack & pinion rail for the gyro to travel on so that it can go up extremely steep inclines without a problem. Hardware list: 3:1 GT2 Belt Pulley set: 4S 1.3 Amp hour Battery: 2-4S 30A ESC: Servo tester: The motor i used is out of production, but pretty much any other brushless motor of a similar KV will work fine.
