Not to be the negative nancy here, but it’s worth making the important distinction that this is only a “Table Topper” as it does not include legs, and I have serious doubts if it would even be rigid enough to support the weight of the field elements+robot even if it did (given how flexible it appears in the video).
Essentially it’s a collapsible field perimeter for use on the ground or an existing large table.
Not that there’s necessarily anything wrong with that, I just felt it was worth pointing out.
I haven’t really paid attention to FLL in a while, but aren’t there usually elements of the field supported by the walls, sometimes crossing over to the adjacent field? Does this table work with those?
What is the stiffness of the sidewalls? Robots often use sidewalls as a means of navigation; either butting up against them or gliding along them with rollers.
My gut feeling is: “this is awesome for quick setup and initial prototyping but absolutely not what you want for final tuning if you use the sidewalls for navigation”
Maybe this could be improved by bending an additional flange over the edge, or even fastening some box tubing around the perimeter.
