Before you begin…

  • Make sure to take your time! All Mission Models serve a purpose/function and improper builds can cause flaws in the game.
  • Make sure to grab all parts listed in the top left corner of each step.
  • When grabbing parts, make sure to take note of the color and length the instructions call for.
  • Organizing beams, axles, and other elements by length can help decrease error margin and save time.
  • Watch for pictures of what you are building. There may be assemblies or sub-assemblies that need to be built more than once. Those will be specified by a 1x, 2x, 3x… etc.
  • The symbol shown below (Figure 1) signifies an orientation/view change. Make sure to align the model to mimic the view shown in that step.

  • Teamwork is vital! It takes many hours for a single person to complete a Challenge Set. As a team, the work can be divided among many people. Many hands make light work! Working as a team can also decrease the margin of error.

Bag 1:

  • Bag 1 contains the Pump Addition, Big Water, Rain, Dirty Water, Sludge, Penalties, and Coach elements.
  • It’s important to note that the Coach elements do not have a function in the game and because of this, they are not mentioned in the Robot Game Field Setup. They’re provided as a fun keepsake for coaches!
  • In bag 1, you will build many Rain and Big Water, so watching out for the multiplier (example: x5) is important.
  • In addition, the Pump Addition is found in the contents of this bag. It is important to note that there is another model that you will find in Bag 2 that has a similar build, so it is critical that you take your time and consider this as you continue with your building.
  • Although it does not have a mechanical function, the Pump Addition can be slightly difficult to build. For example, there are a few times when an element might be placed on top of a similarly colored element. It’s important to double-check that the placement/alignment is correct.

Bag 2:

  • As mentioned previously, this bag contains a similar build to the Pump Addition found in Bag 1. In this bag, you will be building the main Pump System.
  • The Pump System is the first model that includes a true mechanical function that may affect the overall outcome of your team’s performance!
  • Like the Pump Addition found in bag 1, there are a few times when an element might be placed on top of a similarly colored element. It is important to double-check the placement/alignment of these pieces for this reason.
  • There is one main feature I felt the need to point out in the build instructions, which I’ve done by step number.
  • In Step 31, it should be noted that the axle shown must be pressed through the connector below it.

Bag 3:

  • This bag includes the Fountain and Flower.
  • The Fountain and Flower both have seemingly simple mechanical functions, but remember, an incorrect build may affect the overall outcome of your team’s performance! With that said, it is important to take your time and double-check your work.

Bag 4:

  • Bag 4 contains the pieces needed to build the faucet.
  • There is one main feature I felt the need to point out, and I have done so by step number (the number is referring to the number in the top left corner of each step).
  • In Step 47, it is important to make sure that the slide is fully seated and the white side is flat and facing upward (as shown in the Building Instructions) before installing the gear. This is important and if the above measures are not taken, the model will not function properly.

Bag 5:

  • This bag contains the Filter, Optional loop, and Broken/New Pipes.
  • In this bag, you will build a few of the same models, so watching for the multiplier (example: x2) is key!
  • As for the build of the Filter, there is one main feature I felt the need to point out, which I have done by step number (the number is referring to the number in the top left corner of each particular step).
  • In Step 28, it is important to make sure that the slide with rack is completely to the left with the blue facing upward as shown in the Building Instructions before installing the gear. This is important and if the above measures are not taken, the model will not function properly.

Bag 6:

  • This bag contains the Well, Tripod, and Manhole Covers.
  • For the build of the Well, there is one main feature I felt the need to point out, and I have done so by step number (the number is referring to the number in the top left corner of each particular step).
  • In Steps 19 and 26, it is important to note the black 1×2 plate. This is key to stopping the roof of the Well from sliding off!

Bag 7:

  • This bag contains the Water Treatment Plant and Toilet. Some may say that this is the most mechanically involved model of the season. With that said, there are many things to make note of when building this model!
  • First, make sure to take your time. There are many mechanical functions that can affect the overall outcome of your team’s performance if they are built incorrectly.
  • This assembly contains many moving parts and facets. Pay close attention to your build and remember to double-check your work!
  • This model has a lot of orientation changes. It is important to make sure you pay close attention to the orientation/view and adjust/rotate to mimic the orientation shown in that step (See Figure 1 for symbol used when the model is going through an orientation change).
  • As for the build of this model, there are a few features to point out. I have done so by step number (numbers are referring to the number in the top left corner of each particular step).
  • In Step 74, you will be installing the belt/tracks for the Water Treatment Plant skimmer. In this step, it is important to install this in the correct direction. This should be done by having the blue side down and positioned on the left. From here, you should insert the belt/tracks from right to left underneath the gears/rollers it will be wrapped around soon after. If installed incorrectly, this model will function backward of what is intended.
  • In Steps 76-78, you will be installing a gear in the center of the model. This can be quite hard to see in the building instructions but is crucial to the overall function of the model. For this, I recommend looking through these steps prior to installing and locate where this gear will be installed. Next, you should place the gear on the axle and push it inward until it is fully seated as depicted in Steps 77 and 78.
  • The last thing I feel needs to be mentioned is that it’s important to make sure the brown couplings in the back of the model are not being compressed by other LEGO® elements. This would cause many of the surrounding gears to not move as freely as they should. This could cause the main mechanical function of the model to not operate properly and that, in turn, may affect the overall outcome of your team’s performance!

Bag 8:

  • This bag contains the Curbs, Barriers, Water Target, and both halves of the Ramp.
  • In this bag, you will build many of the same models. For example, there will be two Curbs, two Ramp halves, and six Barriers, so watching out for the multiplier (example: x2) is critical for these models.

 Bag 9:

  • This bag contains the Rain Cloud.
  • Building this model can be more complicated that it looks due to the many similar colors being stacked on top of each other, and the many connector pegs needed.
  • Connector pegs have very specific locations on each of the beams. Make sure to double-check that you have located each connector peg in its correct position before continuing to the next step.

Bag 10:

  • This bag contains the House, Firetruck, and SlingShot.
  • These models, although seemingly simple, have many similar colors being stacked on top of each other.
  • Additionally, the House and SlingShot also have mechanical functions. With that said, it is important to take your time! An incorrect build may affect the overall outcome of your team’s performance.
