Its a cutting board from an art store. It is labelled 'Art Mat' and is about 3mm thick. They come in a number of sizes from A4 to A2 and maybe even larger.

That's sort of my point - really complex locomotion systems need more help than we currently give them. Making an 8DOF bot should get a huge weight bonus to make it viable.

Thanks for the heads-up, its craxy how the spots fill up so fast when they used to stay open for months in the past. I guess we have Battlebots to thank for that.
