Self Balancing Gyroscopic Inline Two Wheeler

Here is something a little different: an inline two-wheeler that is balanced with a mechanical gyroscope. I have been building these for several years and finally got one working that uses a servo motor to control the gyro gimbal that keeps the model balanced. I used some of the ideas from Mori, Hiroshi who builds gyroscopic monorail trains and here is his excellent booklet that explains the theories of how they work: https://thebbb.net/free/theories-and...-monorails.pdf

Eventually, my two-wheeler will be RC controlled, except for the gyroscope which is controlled by Arduino Uno.
