       | worth checking out. Lots of interesting robotics projects!

       | Looks great for doing donuts somewhere, but it never looked
       | practical for useful travel in a straight line. Would other
       | materials like tire rubber reduce the negative effects of the
       | balls getting dirty? Add some sort of squeeze to it so the
       | surface is self-cleaning maybe?

         | in the bearing..?

       | hahhahaha Love this!

       | look like it's floating

       | I've always had the impression that James is too wasteful,
       | overengineering, printing massive, impractical plastic things
       | that actually don't need proof they will work because they have
       | precedents, like circus clowns walking on big balls in this case.
       | 
       | Now, seeing all the effort he goes into explaining what he's
       | doing, how, why, and him open sourcing CAD and code, I get it.
       | This is wonderful teaching for product engineers, and while James
       | understandably has to teach sure-fire projects because he wants
       | sponsors to stick, his viewers can use the learning to try
       | riskier projects.

         | their time.

       | great and uplifting at the same time. I enjoy seeing the product

       | financial incentives.
