Driving robot on concert?

[AlexH]

If possible have a spare set of wheels one set for demos and one for competitions.

The standard kop wheels should be fine running on concrete. They might just get a little dirty and not look as shiny. Same goes for the onmi wheels unless you have an a holononic drive setup which I don't think you have coniderong you have a pair of non omni wheels.

We just use standard KOP wheels on our demo bot as asphalt chews up the surface but the wheels aren't expensive and they don't mark wooden gym floors or school hallways/classrooms so they were a good solution for us as that robot is rarely driven on carpet.

KOP wheels are cheap, universal, relatively durable, and replaceable. If you keep your KOP wheels around like my team (we also have 8 pre-2008 joysticks no one will let me throw away 0_o) year after year, you have a free supply of wheels that can work on a "demo bot." If we ever tour with our Lunacy Robot, it will probably get the KOP treatment.
