Here's next week's video, early for Patrons. This one goes out publicly on Tuesday 18th.

I really wanted to experiment with this, but some unexpected things happened (which I could probably have predicted if I'd thought it through).  I have another plan for a one-wheeled robot though which is coming up soon.

MonoWheel V2 - PREVIEW VERSION

It's version 2 of my Monowheel, and this time I decided to try stabilising it with physical spinning gyroscopes so it can stand still while stationary. Some other unexpected things happened though.

I think the tire profile should be more rounded to allow for steering. You may actually want to use the gyroscopic features of the wheel itself. If you roll a coin down the floor, observe how it balances itself. You do need it to reach a higher speed, but at a certain point, it will naturally balance.

Also, you can have a gyroscope aligned in the vertical axis solely for the purpose of accelerating a pivoting force. You throw the center of gravity into a forward axis offset, apply a pivot, and then you can repeatedly correct your sideways axis with each iteration. Your wheel would roll forward and backward pivoting at each time the velocity is zero. Deciding the correct angle to use each time may need adjustment.

Yep - that's like my V1, but it can't stand still on the spot of course.

When you stabilize a gyro on one point of contact, I think it complicates pivoting. I know on an EUC, the inflatable tire has some friction against pivoting, but it also has an effect of traintracking which is similar to how belts ride to the highest point of a pulley. Yeah this is all very interesting!

In the video you say when you try to turn one direction, the wheel goes in the opposite direction and it reminded me of when I was first learning to ride a motorcycle. At slow speeds, you turn the wheel in the direction you want to go. At high speeds, you exert pressure on the handlebars in the opposite direction to steer. This is (at least, how it was explained to me) due to the forces of the spinning wheel maintaining it's orientation. Your spinning flywheels are trying to twist the wheel in the opposite direction of the lean.

At the end of the video I explained that I think is because the whole body of the machine is no longer upright when the gyro lean it which is casing twist in a non-vertical axis.
