FIRST LEGO League Table
----------------------------------------------------------------------------------------------------------------------------- -----------------------------------
The field is where the Robot Game takes place.
It consists of a field mat, on a table, with mission models arranged on top.
The field mat and the LEGO
®
pieces for building the mission models are part of your Field Setup Kit.
The instructions for building the mission models are at http://www.firstlegoleague.org/missionmodelbuildinstructions
The instructions for how to build the table are below.

TABLE CONSTRUCTION
The Robot Game takes place on a specially designed table, so you’ll need to build one to practice on if you don’t already
have access to one. With safety, weight, height, and cost in mind, a simple design is offered here, but as long as your
surface is smooth, and your border walls are sized and located properly, how you build the understructure is up to you.
The construction is simple, but does require some wood-working skills.
At a tournament, two tables are placed back to back, but you only operate on one table, so you only need to build one
table to practice on. We’ll call your practice table a “half-table.”
Most challenges have a “shared” mission model, which rests
partly on your table, and partly on the other team’s table. So in
addition to building your table, you’ll need to build a tiny portion
of a second table, so both halves of the shared model are
supported. We’ll call this added section the “dummy section.”
Here are the instructions for building one “half-table,” plus a
dummy section:
Materials
Field Setup Kit (mission model LEGO elements, mat, CD, Dual Lock™)
sanded plywood (or other very smooth board) 96” X 48” X at least 3/8” (2438mm X 1219mm X 10mm)
two-by-three, 8’ (2438mm) [actual cross-section = 1-1/2” X 2-1/2” (38mm X 64mm)]
coarse drywall screws, 2-1/2” (64mm)
saw horses, about 24” (610mm) high and 36” (914mm) wide
Parts
96” X 48”
(2438mm X 1219mm)
H 24” W 36”
(610mm) (914mm)
Assembly
Step 1 - Determine which face of the plywood (A) is least smooth, and consider that the bottom face. On the bottom face,
locate, clamp, and screw on the stiffeners (D) (about every 18” or 457mm). Be sure screw head tops are flush. Sand any
splinters.
Step 2 - On the top face of the plywood, locate, clamp, and screw on the border walls (B,C) around the top perimeter.
The wall-to-wall dimensions must measure 93±1/8” by 45±1/8” (2362±3mm by 1143±3mm).
The height of B and C must measure 3±1/2” (77±13mm). Note the use of the “plus or minus symbol.” This means the
maximum allowable height is three and a half inches (ninety millimeters) and the minimum height is two and a half
inches (sixty-four millimeters).
All border walls must be the same height as each other on any and all tables at a tournament.
Border heights at a tournament may be different than those on your practice table.
