I would like to use 8 inch wheel hub motors but for some reason they are not cheap in Canada. ...
The cost is what it is. I am sure that most golfers who are either too lazy or too out of shape to haul around their own set of golf clubs will compensate by acquiring boatloads of cash to spend on greens fees, country club memberships, and fancy golf carts. So, if you build it, someone will buy it.
... They are on eBay but the shipping cost is a lot. ...
Irrelevant. The seller (you!) just adds shipping cost to the selling price.
... I may want to make several of these so I would need to source out the motor wheels. ...
I didn't think you wanted to start manufacturing motors. You may be able to get quantity discounts.
... The cart is actually a golf push cart. I listed as utility to make it simple.
Nothing about this project will be simple, except the change from two-wheel "hoverboard" support to four-wheel "cart" support adds some credibility to the feasibility of a successful, i.e., working design. You still have to figure out how you want to remote control the two driven wheels.
Does this fancy golf cart follow the golfer around at a respectful distance? Or does the golfer or his caddy steer and control it with a radio-controlled joy stick or similar apparatus? Is there a model with an option that automagically selects the correct golf club, based on distance to the green, lay of the ball, experience of the golfer and various other important factors? Will your cart know what a Mulligan is? How to declare and play it? Answers to these questions may have serious design consequences!
How do you plan to power your contraption? I am 99 44/100% sure that no golf course will allow golf carts with internal combustion engines to pollute their pristine atmosphere and ambiance with noise and exhaust fumes. And really long electrical extension cords are probably a non-starter too. That just leaves quiet, non-polluting, fuel cells or rechargeable batteries, assuming you don't want the bother of licensing a
radioactive isotope heat source to drive a thermopile, like NASA uses for long-range space missions far from the Sun's illumination. Solar power is probably not an option for you either, since it is a known fact that serious golfers will play in the rain and also during thunder storms.
So, please let us know how you intend to proceed.
Ohhhh so it doesn't really hover !!
AFAIK, none of the so-called "hoverboards" actually hover. They all seem to be some variation of a two-wheeled
Segway clone, now that sensors and microprocessors have advanced enough to make such things affordable to the masses. Still waiting for Mr. Fusion and anti-gravity invention to implement "Back to the Future" type hovercraft. Could be a long wait.
