World's First SCREW-BIKE

Published 2024-04-15
Do you remember when I made a bicycle with an omni-wheel on the front? A while later I moved on and tried to make a bike with two omni-wheels.
As soon as I’d assembled that version I realised it would have been better to have made Mecanum wheels, which have the little wheels slanted all around them. These are typically used on the four corners of a robot so it can move in any direction, but I want to put them all in a line, so the bike still balances sideways, but can screw itself along.

For future builds you intend to ride, I strongly recommend adding a dead-man style safety, not just the push button, think jet-ski where it's a cord around your wrist in case you fall off.
-
this deserves a followup video with passing a silly obstacle course

"Look ma, I made an insanely complex self stabilizing people transporting machine. Combining highly sophisticated knowledge of mechanical engineering, 3d-crafting, electronics and software engineering. Producing a fully functional prototype, that would have taken a well founded and staffed company a few dozen man-years to complete. And I did it in my DIY-shop in a few months, and made it look easy!" "Stop that nonsense James, and eat your porridge! "
-
I am astonished by how well your designs work out. Most other 3D printing guys go through a dozen versions before they come up with something that doesn't break immediately.
-
You have to respect a proper scientist and engineer. Making this open source rather than trying to monetize it for all it's worth. You're absolutely phenomenal James. I could see this being used instead of a camera on a track.
-
i'd change the controls to use both twist grips to control turning, twisting one twist grip turns the bike in that direction and twisting both moves the bike forward/backward depending on the direction switch, this would make it easier to steer at speed since you can just slightly let off one of the twist grips to steer
-
I can't imagine how obnoxious it was to attach the top wedges to the top plate. You pt so much effort into the little things in your videos and then gloss over them. Your patience and determination is inspiring.
-
It would have nice to see the bike just go forward in a straight line just like a regular bike. Sort of in the vein of showing all its modes of motion. What a project!! Great work!!!
-
People: That's like reinventing the Wheel James Burton: Yes
-
The number of entire categories of knowledge required for this: programming, autocad, electronics, motors, 3D printing, welding, math & physics... and then all the tools, materials and space. This is a MIND-BOGGLING project for one person 😮🤯😵💫. Just wow! 👏👏👏
-
I am amazed at the way the bike balances itself when near still or motionless and when you move either to the left or right with no forward or reverse it just looks so awesome... I mean its just absolutely solid and not making any micro movements that I can see.. It is almost like its got 4 wheels with one being in each corner... that is amazing...
-
My dude, that was incredible, amazing job! I was actually just talking with a friend about using this style of wheel on cars, as it would change the dynamics on the road significantly! The applications of this are so cool though! Keep refining this, and it will be something truly groundbreaking!
-
“Screw bike mecanum wheel omnidirectional colinear drive bike project” really rolls off the tongue!
-
Any other channel would turn this into 20 build videos. This one is informed by all the omni bikes that came before. It looks like you had an idea, you executed it and it worked beyond your expectations with very little adjusting. Great work!
-
Incredible build James! Watch your fingers in those huge belts. Super job!
-
Lots of spinning and sideways demos, but very little going forward video. It is amazing and you did a fantastic job on the design and build. Thank you for sharing with us.
-
I am continuously amazed by the patience of this man to wait 100s of hours for his parts to print and then assemble them by hand cranking a hydraulic press!!
-
I've been working on a set of custom mecanum wheels for the past year for my engineering capstone project and I just wanted to let you know that this video is both incredibly triggering and incredibly impressive to me. You did an amazing job! :D
-
It is possible that these design ideas are suitable for automatic forklifts in warehouses. Great job.
-
Amazing stuff. Really waited for a demo seeing it go straight forward in its top speed though...
