Helper Robots ICH Ref

Each competitor gets their own tiny communication robot. You can customize them as long as they are small enough to stay out of the way and can do these things:

Translate all languages between competitors and staff with written and audible language. 
Browse the internet.
Skype with your friends and family.
Play music.

The robot doesn't need to have a personality or any special voice of it's own, but you can add anything of that sort if you wish. It's purpose and job is to show you the rules and particulars of each round. It will answer whatever question it is able to and let you talk with the other competitors and whoever wants to interview the competitors.  

There may be some that seem to float around by themselves, but normally everyone on staff (and the competitors) in the stadium has one with them.
