Event Description

We are pulling out all the stops: This is the premiere event for the unveiling of the newest 12lb/30lb arena on the West Coast: the SCAR arena! All are welcome to spectate, and the event is all ages. 

To allow as many builders as possible for this event, we are limiting registration to one robot per team per weightclass, with additional robots being put on the waitlist. If you have found registration is full, please email me and we may be able to make space for you.  If you are for whatever reason unable to bring your own table and chairs, we have a very small amount available on site, however you will have to email me to reserve those and they will be first come first serve.  Also, if you have extra needs outside of things mentioned please contact me and we'll see what we can do to address those needs.

All attendees and spectators will be required to fill in event paperwork at the door for insurance purposes.
