Nice motorbike, but I like the robot better.

I think the main problem is either you build your own arena or visit a live event. The first is expensive in materials needed and you have to work hard and the second is expensive in travel costs but more fun.
Consult with Helmut from Austria, together with the German and Austrian robots you might have a nice core, a group of dedicated roboteers who can organize a live event or at least a get-together for a few fights.

But I urge you to visit a British live event first, like Roaming Robots, so that you can see how it is done. See the live events thread on this forum, I am certain you will find an event to your liking and you will be welcome there. If I am correct Roaming Robots has a mobile arena that you can rent. At least they can give you the explanation on how to organize a live event in a way that guarantees safety to both roboteers and audience.

Italy is far away from us (Im Belgian). But who knows ? We might consider it for a holiday destination...
