I never have. I’m mostly turned off by them after watching various videos showing the trouble with friction (or lack of) on various surfaces.

But that doesn’t mean I’m not curious  Is there one that you’re looking at?

ps, the navigator kind of sucks compared to the better navigator. I’d consider using that if you’re not yet

I really haven't selected a platform yet. I may just buy 4 wheels on Amazon (approx $30 to $40) and throw something together to have a play.  I was looking for something that can support a robot arm Lidar, Sensors etc so about 40 to 50 pound weight.

But then I just saw this.  NO DON'T DO IT.  but it has gesture control and its only $55 CAD on amazon (OK I am sidetracked).  Yeah just gonna buy 4 wheels and attach them to a bridge and some motors ... umm but its its in my cart NO, having flashbacks to Jeremies hack remember his $20 Walmart car (Oh they are still in stock)  https://www.walmart.ca/en/ip/150th-scale-yamaha-nano-yxz-with-drift-function-wheels-carbon-blue-color-carbon-and-blue/6000201633689

Yah that video shows what I’ve been seeing. Had to change surfaces for the sideways traction to work. Think it’s fun for rc toys but not sure about robots needing resolution

I ordered this yeah I could have just ordered wheels and motors but more expensive and all I need to add is 2 hbridge so I figured it would work as a good prototype platform. I will circle back in 2 -3 weeks when and if  it turns up.

Hello @Nink!

I have! It started with my Live hack where I hacked a $20 RC toy with Mecanum wheels from Walmart. While that didn't work out as planned, I broke the gear boxes in the car likely from feeding them too much voltage, I did move on from there and have had great results.

I wanted to point out that there is a difference between Omni-wheels and Mecanum wheels. Omni-wheels have their rubber barrels running in parallel with the wheel, whereas mecanum wheels have their barrels mounted at an angle.

While you will have problems with Omni wheels on a slanted surface, you won't have any issues with mecanum wheels. Mecanum wheels work against each other when not spinning, there are two types L and R that won't let you slide on a tilted surface. I feel that mecanum wheels are also far superior as they give you the ability to do NW,SW,NE, & SE strafing patterns.

Omni Wheel:

Thanks for the detailed info Jeremie,  I appreciate you provided the difference between omni and mecanum wheels.  Looking forward to getting the little test platform and hopefully this should be sufficient to mount a Rock Pi X, Battery, Lidar and a couple of sensors to see how well it performs.

I came across this chassis today - it is a little pricy but looks neat: https://www.amazon.ca/dp/B088PRGQJ1

Nice and classy. Low profile. Looks like it would be good on flat surfaces but easy to get stuck on anything else.
