What about if we could actively drive the smaller passive wheels around the circumference of an omni-wheel? Then we could have a robot with one omni-wheel and make it balance in both axes.
I found a project called OmBURo, and I’ll a put a link to the video and details in the description. This robot does exactly what I’m looking for – it consists of one big omni-wheel with driven wheels around its circumference. This allows it to balance in both axes.
The Honda U3-X is a personal mobility solution, and it also features a two-axis actively driven omni-wheel. This is larger and looks pretty robust since it can carry a human.

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.
