It’s pretty hard to walk on a tightrope but I thought I’d have a go. I set up a bar which is a steel scaffold pole and tried my best to walk along it. Sometimes I could almost make it to the end, but most of the time I did far worse than that. It’s a bit easier if you crouch right down and use your arms to help you balance, but standing up tall makes it even harder. Standing still on the spot for any length of time is practically impossible.
But could I make a device that would help me balance?
I’ve built a couple of projects that used reaction wheels to make a device balance on the spot. This is a wheel which rotates and dynamically accelerates in either direction based on the angle of the device. Force equals mass times acceleration, so we only get a reaction force when the wheel is accelerating or changing direction.
But how big would a reaction wheel need to be to help me balance so I can walk all the way down the beam?

XROBOTS

Former toy designer, current YouTube maker and general robotics, electrical and mechanical engineer, I’m a fan of doing it yourself and innovation by trial and error. My channel is where I share some of my useful and notsouseful inventions, designs and maker advice. Iron Man is my goto cosplay, and 3D printing can solve most issues broken bolts, missing parts, world hunger, you name it.

XRobots is the community around my content where you can get in touch, share tips and advice, and more build FAQs, schematics and designs are also available.
