Hello everyone, I am very new to this side of things and am hopeful I can be pointed in the right direction. I own an escape room company in OKC and have created some incredible special effects, but this area of expertise is not really in my wheelhouse. We are currently buildi…

It looks nice! I’ve did search RobotShop product pages, and here is what I have found that might suit your project: https://www.robotshop.com/products/100mm-double-plastic-omni-wheel-central-bearing https://www.robotshop.com/products/e-s-motor-36d-brushless-dc-planetary-gear-m…

Thank you very much! Which hubs are needed to connect the shaft to the omni wheel?

So something like this: [image] I believe this one would fit: https://www.robotshop.com/products/6mm-shaft-universal-aluminum-mounting-hub Maybe you would need to drill out the hole in the center, if your shaft of the motor is bigger than 6mm. Or you can design your own spe…

To confirm, the omniwheels shown in the images above should be perpendicular to the sphere: [image]

Yes, that was ChatGPt’s failed attempt at rendering the appropriate orientation. Is there a baseplate/chassis you’d recommend? I see your rendering has the walls already angled at the proper pitch. I was looking at a flat baseplate where the angle would be set with the motor m…

You’ll likely need to custom make one, and not sure adapting an existing mobile robot kit/ mechanics would be worth it. Consider learning a bif of CAD to be able to draw it yourself. At 14 pounts, the motor’s output shaft can likely support the load directly, but not sure thin al…

Definitely not versed in CAD, but we have a 3D Printer, CNC for wood/plastic and have a master welder who works for us. It shouldn’t be an issue to manufacture something. I just didn’t know if there was anything “off the shelf” that could be utilized that is reliable and strong…
