I previously built an omni-directional robot with ball-shaped wheels. Each wheel had a hemisphere which if free moving. There were some suggestions that these hemispheres could be powered, although we'd have to vary the velocity as the main axel rotates because a small circumference will be touching the ground. We can use this to our advantage however to make a continually variable reduction or continually variable transmission (CVT). Often CVTs use belts running between two pulleys which can change diameter, but in this video we're going to use a ball.

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 not-so-useful inventions, designs and maker advice. Iron Man is my go-to 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.
