This Robot Design is AMAZING! But is it worth the STRUGGLE? (Omniwheel)
video description
James Bruton has also built and experimented with many many different and more advanced omniwheel configurations and i highly recommend his videos if you haven't seen them! his projects are all 3d printed and he also shares all his files so you can try them out if theres anything you like.

GreatScott!
Thanks for watching this video! Now the robot design in the end is certainly not perfect. But like I said; by using other rollers+motors, this robot can become way more precise and stable. Also the code of the robot is certainly not perfect. I think I messed up the math at some point. I will have to figure that one out as well when I get to make a part 2. I think I even wrote a wrong equation on my vector paper. mistakes happen. But I think the overall idea of the video should still be pretty clear; -)

How confident are you that the power saved from not needing to rotate is greater than the power lost from the increased rolling resistance that comes from driving omniwheels at an angle? Even in an optimal work load (where the need to change direction is more common than going in one direction for a while, I'm suspicious of the power savings.
I can believe that these wheels are beneficial when you need precise movements, though.

Paint silicone over the rollers for grip. Assuming your using PLA, don't even need to scuff the surface for good stick, the layer lines will do that all on their own. Maybe a quick rinse with distilled water or IPA to clean the surface of the plastic first but in my experience it's a challenge to get silicone to not stick to PLA.

Nice work, Scott! Very interesting project.
But, being a trig challenged, simple minded person, I'm wondering what was gained by positioning the wheels 120 degrees, instead of 3 omniwheels pointing in the same direction? Isn't it usually better to KISS?

This guy is Great indeed! From the mechanical design, components selection, electrical wiring to the actual assembly, everything is so beautifully detailed and professionally mounted. Props to you Scott and continue being awesome!

Makes me remind of the Mecanum wheels, a 45 degree roller wheels that use in the Fork lifts. It's actually uses a 2 wheels at a variable speed in each of the wheels to control the direction of the lift.

It might be worth trying Mechanum wheels as an alternative, I think they'd be less prone to slipping and therefore be more usable without implementing any feedback response. They're also just kinda neat.

You can't really put those on a vaccum robot though, since they would run across dirty surfaces too much. Vacuum robots wipe away dust in front of their wheels so they remain clean for a longer duration.

Could you fix the second problem by printing the rollers with trenches in them for the O-rings to slit into so they stay put and evenly spaced out over the length of the individual roller?
