Monowheel - PREVIEW VERSION

I've been watching a lot of Monowheel videos recently, and they look like a lot of fun. I decided I should build one and also try to add some active control so it's easier to drive.

Really good James. I wonder if you could put a 90 degree gearbox on the motor so that it can be aligned inside the wheel better. And clearly needs some crash plates/ cages around the electrics. But I think it has a lot of potential and looks really fun to drive.

Love it! I've been toying with building something similar, but with herringbone gears, to possibly keep the gears within the wheel, without the "outer" bearings.

Was wondering about using active gyros for this! Would be fascinating to see that, especially how well it works as it scales up in size.

Maybe it is worth having the stabilizing weights extend out a bit further, like a tightrope walker does with the stick across their shoulders, to give added inertia/stability. Even if the washers started 10 or 15 cm out, it could have a strong effect.

They would probably need to be higher up so they don't scrap on the ground when it banks. Probably would have been worth trying though.

I think it's attracted to your PC, either that or it's scared of the stairs 🤔

Seeing your BB-8 build again made me nostalgic. Would love to see a new ball wheel design maybe a two wheel "bike" linked as if two BB-8 heads linked them. This would give you a chance to talk about what you've learned since your last BB-8 build and why the changes in the design are valuable. Without building another "droid".

I'd love to do another BB-8 build, but it's not really going to attract the interest it used to. We'll see what comes up in new Star Wars movies and series I guess ;-)

Scott Cress

Don't have to call it a BB-8 build call it Wheely ball or whatever you'd like. My point is that your balls you've built in the past would be an excellent example of unique locomotion like what you've been building all year. Also referencing previous build videos would drive new viewers to your older content Older viewers, like me, would appreciate the call back. In addition, you already have a lot of the CAD for the balls already built so making a double ball "bike" or 3 or 4 balled vehicle should be pretty quick. I see it as a win/win project.

XRobots

I'll think about it. They say you should repeat your best videos very 3-6 months ;-)
