A cradle isnt much more than a frame, made from any material , that makes sure the robots wheels cannot touch the surface of anything, so, if the drive is accidentialy activated, the robot wont destroy the pits. Of course ,the cradles need to be sturdy and put the robot stabile.

And a cradle is mandated for every weightclass.

Now, our featherweight cradles are just screwed together 4 by 4s.
