FIRST provides building instructions for a wooden table, but here are some portable options. Note that the closer your table is to the specs, the better your experience will be at a competition. Therefore, building a table out of alternate materials (foam board, corrugated plastic, metal, etc.) can impact the operation of your robot.

The following discussion is based on conversations in the Facebook Group FLL: Share & Learn.

There may be other options such as “corrugated plastic”. However, the AndyMark table is the closest for-purchase table to an actual wooden competition table. The closer your table is to the specs, the better your experience will be at a competition.
