This is my first attempt to build gyro-stabilized system for 2-inline-wheeled platform. I use model steam engine flywheel for the gyroscope, door hinge as steering unit and wheels from inline skates. I'm planning to add some motors for active gyro controlling, forward-backward motion and steering. At this point this thing would not stand by itself for a long period of time. I need to add an active gyro control system.
The gyroscope natural movement (swing) you see on video is the precession. By actively control the gimbal (manipulating precession), maybe I can get better stability.
