Ideas for Creating a Wonder League Robotics Competition Mat

Aug 5, 2020

Launching September 14, 2020: UPDATED FOR YEAR 6

Buy It, Print It, Make It!

The Wonder League Robotics Competition (aka WLRC) is launching again— and we are determined to make it the best year yet. This year’s theme takes Dash and Cue on a new adventure with some of Dash’s friends at Cartoon Network. The competition starts September 14, 2020! That means it’s time to get those mats ready for the big day so that the teams can dive right in. In order to set the stage for all three missions, your teams will need a 5 x 8 square grid Wonder League mat with the following specifications:

  • sized 150 cm x 240 cm (think landscape format)
  • Y-axis is labeled A-E and X-axis is labeled 1–8
  • Cell A1 is in lower left-hand corner
  • Dash or Cue needs to be able to roll across and not have anything interfere with its wheels (sorry, no shag carpet!)

In order to keep things simple and costs low, we are keeping the same theme from year 5 for this year’s Wonder League mat.  The themed mats can be purchased through Geyer, a third-party vendor. Geyer has the themed mat, a non-themed generic mat, and even a chroma-key green background version for sale — can you say “green screen” (check out this video based on #WLRC coach Mrs. Eckstein’s idea from a couple of years ago.

Did know that you can use any of the Wonder League mats from previous years  —  the dimensions are the same. For those of you in need of a new mat, there are three basic options:

OPTION 1: BUY ONE. Check out the Wonder League mat options at Geyer. Just note: Geyer is an independent party; we are not responsible for any issues with the design, quality, or shipping. For those in Europe looking to purchase a mat, please see mat options here.

OPTION 2: PRINT ONE. We also are providing our coaches with both our themed mat design and a digital image of the mat (click on link for files) in two colors: black or white. If you want to print this file, you will need to find a sign or banner printer  —  check out retailers like Staples, Office Depot, FedEx/Kinko’s, Vistaprint.com, Signs.com or Esigns.com, which has a self-print option. You’ll need to tell them that you have:

  • a black and white “.eps file”
  • an image that is 165 cm x 255 cm (accounts for 7.5-cm border)

In addition, you can also print this year’s themed mat through your favorite local or online printer.  You can access this file through the Coaches’ Corner. Be sure to register as a coach to gain access to all our free resources and supporting materials for this year’s competition and beyond.

Your choice! Both are digital .eps files.

We recommend printing on 13 oz. vinyl  —  it will lie flat but can be rolled for storage. Other options for materials include 24 lb. paper (but do consider longevity needs) or foam board (but do consider space constraints).

OPTION 3: MAKE ONE. We are big fans of this option! And we have seen so many do-it-yourself (DIY) ideas. If you have the space, you can use painter’s tape and create a grid on the floor or on a rug. We have even seen a grid drawn in chalk on a sidewalk. Done!

We recently heard that one classroom teacher took her small 5 x 8 area rug, flipped it over, and created a grid on the back with painter’s tape. She created a two-in-one: a rug for class time and a grid for robot time!

Painters tape on the underside of an area rug!

Another floor option is to use painter’s tape to outline square tiles on linoleum floors, and then put the grid letters and numbers along the axes on Post-It notes. Who knew school hallways could be a robot stomping ground!

Many, though, want something that they can move because of lack of space. Options for a portable gridded mat include making one on a piece of vinyl, a plastic tarp, a drop cloth, or a shower curtain.

The total size of the grid should be 150 cm x 240 cm, which includes grid lines. So you can use a paint pen, Sharpie, or thin painter’s tape for the lines. If you’re using tape, just center it on the measurement hash marks. It’s up to you to decide if you want a border or not.

Used a yard stick (in cm), paint pen, and plastic tarp, and first created a squared-off border since the tarp wasn’t quite even on the edges. Then added hash marks to mark 30 cm horizontally and vertically as guides for the grid lines. Last, added A-E on y-axis and 1–8 label on x-axis (A1 in lower left-hand corner).

If you want to use painter’s tape for your grid lines, center the tape over any guiding lines or hashmarks. Then you’re still guaranteed to have 30-cm squares.

Coach Natalie Oberbeck recently shared this back-saving method for making a grid on a felt-backed vinyl tablecloth. She made a transparency out of the white mat image, and then projected it on the wall using an overhead projector. She then used a yard stick to trace straight lines on the tablecloth she taped to the wall. (Natalie recommends getting a piece larger than the grid size to allow for “fudging”!)

Thanks for the clever idea, Natalie Oberbeck!

Coach Joshua Jordan shared his method for creating economical mats made out of banner material. He outlined the following steps:

  1. Purchase a roll of banner material from US Cutter.
  2. Make a WLRC stencil out of card stock.
  3. Buy letter and number stencils.
  4. Buy spray paint.
  5. Measure out 30-cm squares and mark.
  6. Tape grid with 3/4″ masking tape.
  7. Go to town with spray paint! (I applied mist coats to everything to conserve paint, and I really like the way it looks.)
  8. (optional) Apply a light coat of Plasti Dip to the back to prevent skidding.
We love “budget ideas,” Coach Jordan!
