Omniwheels comparison, tell us about yours?

Hi everybody,

we have a couple (lots) of questions about your omniwheels (specifically for this this project but also for all new teams just starting to build robots to see) and would love it if you could share some detailed answers in replies as well as answer the polls below because we would like to assemble a comparison chart of different omniwheel solutions and their respective pros and cons.

  • Can I see a picture of your wheels?
  • How many wheels does your robot have?
  • How long have you been using the same wheels?
  • What are the biggest problems you have with your wheels?
  • What league(s) are you playing with them (are there any weight considerations between LWL/OL for example)?
  • How many spare wheels do you keep in case one breaks?
  • Where/how did you get your wheels?
    • Did you buy them (if so, maybe link to where you got them)?
      • If so, where did you buy them?
      • What model did you buy?
      • How much did it cost you per wheel?
    • Did you make wheels yourselves?
      • If so, did a company manufacture parts for you or also do assembly?
      • If you manufactured yourselves, what parts and machinery did you use to do it?

How did you get your wheels?

  • We bought our wheels
  • We designed our wheels, but had them made completely
  • We designed our wheels, had parts made and assembled ourselves
  • We designed and manufactured our wheels ourselves (almost) completely
  • Something else, will explain below

How many spare wheels do you keep?

  • None, because they don’t break
  • None, because they don’t break often and are are easy to fix
  • None, because they break sometimes but are easy to fix
  • 1 but not used it yet
  • 2-3 but not used them yet
  • More than 3 but not used them yet
  • 1 that we’ve had to use
  • 2-3 some of which we had to use
  • More than 3 some of which we had to use

Wheel problems (multiple choices possible)

  • Wheels damage carpet
  • Losing subwheels
  • Subwheels losing rubber tires
  • Wheels falling off
  • Something else, explain below

How expensive are your wheels (per wheel)?

  • <10US$ plus our time for building them
  • 10US$ to 20 US$ plus our time for building them
  • 20US$ to 40 US$ plus our time for building them
  • 40US$ to 60 US$ plus our time for building them
  • 60US$ to 90 US$ plus our time for building them
  • More than 90US$ plus our time for building them
  • <10US$ for buying the whole wheel
  • 10US$ to 20 US$ for buying the whole wheel
  • 20US$ to 40 US$ for buying the whole wheel
  • 40US$ to 60 US$ for buying the whole wheel
  • 60US$ to 90 US$ for buying the whole wheel
  • More than 90US$ for buying the whole wheel
  • <10US$ but it would be more expensive without sponsoring
  • 10US$ to 20 US$ but it would be more without sponsoring
  • 20US$ to 40 US$ but it would be more without sponsoring
  • 40US$ to 60 US$ but it would be more without sponsoring
  • 60US$ to 90 US$ but it would be more without sponsoring
  • More than 90US$ but it would be more without sponsoring

Thank you for helping us and everybody else get a better idea how you get your wheels.

Cheers

I will start a list of commercially available wheels:

  • GTFRobots sells wheels that some of the teams I spoke to (at RCJ European Championship last week) use
  • There is another shop I forgot that I will put here as soon as I find out again
  • If you post your source I will add it to the list
