I am looking forward to making a Beetle weight but first I would like to see the arena finished and comments to the effect the EO's would allow them at the meetings.
The second point I don't think would be a problem as Robo challenge are making an arena!
But work on designs won't start here, until an arena has been finished, examined and passed.
I am hopeful this will be this year but till it's done or a firm date published, I would not get too keen on building the robots.
