This tag collects video tutorials showing attachments that accomplish the missions mostly 8-9 out of 10 times. These are accurate, precise, reliable attachments. They are interesting because of their consistency and high reliability. On each run the same behaviour is repeated and the mission is accomplish almost 100% of the time.
Short, direct, and almost identical every time. This 10 out of 10 tutorial from the FIRST LEGO League 2025-2026 UNEARTHED competition puts the Smaller Pancake box robot and the Site Marking attachment through ten flag deliveries for Mission 15.
Using everything that we've learned about LEGO Education SPIKE Prime competition programming we arrive at the final boss mission - how do we consistently reach a mission model at the other end of the field. Consistently. Every time. We use line following, motion sensor, counting of lines and border alignment. All the different concepts that we've looked at separately are now implemented together.
When the attachment is simple, preparation makes all the difference. In this 10 out of 10 tutorial for the FIRST LEGO League 2025–2026 UNEARTHED competition, the Smaller Pancake box robot and the Forum attachment deliver the collected artifacts to Mission 14: Forum across ten consecutive attempts.
Long runs are an excellent test of consistency. In this ten-attempt tutorial from the FIRST LEGO League 2025–2026 UNEARTHED competition, we put the Smaller Pancake box robot and the M14 and M15 transport attachment through one of the longest runs on the field.
This is a 10 out of 10 video tutorial for the FIRST LEGO League 2020 RePLAY robotics competition and the Treadmill mission. We build a robot with consistent behavior that is able to achieve the mission every time
The bench mission was a video tutorial that we recorded several times. It was really hard to get it 10 out of 10. The reason was the shear complexity of the mission. There are three things that should happen in this mission at once which was extremely difficult. What you will see in the tutorial is how this attachment behaves
Even a simple lifting mechanism depends on a precise approach. In this 10 out of 10 analysis of Mission 13: Statue Rebuild from the FIRST LEGO League 2025–2026 UNEARTHED competition, we put the Smaller Pancake box robot and the Statue Rebuild attachment through ten consecutive attempts.
Accuracy and consistency is the topic of this tutorial, as all 10 out of 10 tutorials are at FLLCasts. We use a robot build only from LEGO Mindstorms Robot Inventor parts and we accomplish the mission 10 out of 10 times. You will see how we use an active gear attachment to catch the wheel and pull it to the black circle, which accomplishes the mission
Power and consistency can go hand in hand. In this ten-run FIRST LEGO League UNEARTHED season test, the Smaller Pancake box robot and the Silo attachment tackle Mission 8, demonstrating why three well-balanced strikes produce such dependable results.
Can a run be 100% successful and still leave room for improvement? In this 10 out of 10 tutorial for the FLL UNEARTHED season, we evaluate the Smaller Pancake box robot with the shared M05-M07 attachment on Mission 5 and Mission 6.
As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it.
(we are releasing the video without explanations and will add the explanations later)
Mission 7 looks playful in a single run; ten attempts show how much it depends on the table. In this FLL 2025 UNEARTHED competition test, the Smaller Pancake box robot uses the Heavy Lifting attachment after aligning against the wall.
The hook can be engineered perfectly and still miss if the robot begins at the wrong angle. This ten-run analysis of Mission 9: What's on Sale in the FIRST LEGO League UNEARTHED season follows the Smaller Pancake box robot with its roof-and-market attachment.
Fast runs are only valuable when they survive repetition. This 10 out of 10 tutorial tests the Smaller Pancake box robot and the Tip the Scales attachment on Mission 10 in the FIRST LEGO League 2025-2026 UNEARTHED competition.
Small variations in the approach do not always have to change the score. In this 10 out of 10 test from the FLL 2025-2026 UNEARTHED competition, the Smaller Pancake box robot repeats Mission 11: Angler Artifacts with the same geared attachment ten times.
Retrieving the artifact once is satisfying; doing it ten times without touching the supports is the real test. This FIRST LEGO League UNEARTHED season video puts the Smaller Pancake box robot and the Careful Recovery attachment through ten runs of Mission 04.
Can a motor-free mechanism repeat a multi-mission run without adjustments? This 10 out of 10 tutorial follows the Smaller Pancake box robot and the Map Reveal and Mineshaft Explorer attachment through M02 and M03 in the FIRST LEGO League 2025-2026 UNEARTHED competition.
Ten consecutive attempts reveal far more than a single polished run. In this FLL 2025-2026 UNEARTHED competition reliability test, the Smaller Pancake box robot and the Surface Brushing attachment take on Mission 01.
Discover why this solution achieves a perfect 10 out of 10 successful runs in the FIRST LEGO League 2025-2026 UNEARTHED competition. Using the Smaller Pancake box robot together with this passive attachment, we analyze the design choices that make the completion of Mission 15: Site Marking and Mission 12: Salvage Operation remarkably consistent.
This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever.
This video tutorial focuses on accomplishing M05 Angler Fish, M09 Unexpected Encounter, collecting samples for M14 Sample Collection, 3 Krill for M12 Feed the Whale, and Reef Segments for M03 Coral Reef of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run achieves a perfect 10 out of 10 score across these missions in one continuous sequence.
The robot collects and delivers samples, gathers krill and reef segments, pushes the Unknown Creature into the Cold Seep, and engages mission models with precision. The path is optimized for efficiency, combining multiple scoring actions with minimal wasted movement. You can watch the full explaining tutorial here.
This video tutorial focuses on accomplishing M8 Artificial Habitat of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a simple active pinless attachment mounted at the front of the robot for precise engagement with the mission model.
The goal is a perfect 10 out of 10 runs by positioning all four crabs upright with their yellow bases touching the mat. You can find the full explaining tutorial here.
This video tutorial demonstrates a 10 out of 10 on M13 Change Shipping Lanes, along with partial completion of M09 Unexpected Encounter and M12 Feed the Whale in the FIRST LEGO League 2024-2025 SUBMERGED Challenge, using the Nautiq box robot (a LEGO Education SPIKE Prime robot).
This 10 out of 10 video tutorial focuses on the flawless accomplishment of M05 Angler Fish, M09 Unexpected Encounter, M10 Send over the Submersible, and M11 Sonar Discovery of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot.
The run uses a combination of aligning, front, and back attachments to execute multiple tasks in one run, including a rotation transfer system using a single long axle for M11, early execution of M10 for a strategic edge, and sensor-based alignment for precision. Despite the reduced per-run accuracy due to the mission count, this method ensures that when the run works, it secures an exceptionally high score.
This video tutorial focuses on accomplishing M10 Send Over the Submersible of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot. In this series of test runs, the goal is to achieve 10 out of 10 successful deliveries where the submersible reaches the opposing field, and the robot disengages without touching the mission model at the match’s end.
The run uses a simple pinless attachment with stopping beams for consistent positioning, combined with programming that integrates a parallel timer for perfect match-end execution. This setup gives the robot the highest possible success rate for both mission requirements across repeated trials.
This video tutorial focuses on accomplishing M11 Sonar Discovery and M12 Feed the Whale of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot. The goal is to achieve 10 out of 10 successful completions, with the robot reliably rotating the sonar and feeding the whale in every trial.
The run uses a combined two-part attachment where the front section opens the whale’s mouth and drops the krill while the rear section uses a chain and hook mechanism to rotate the sonar. The programming ensures precise timing, correct hook positioning, and a small forward adjustment to avoid snagging, enabling consistent results across all attempts.
This video is part of a series where we show you how our Box Robot accomplished the M08 Elevator mission with 100% accuracy. The idea is that the robot pushes with enought force in the right spot, which makes the elevator turn over. The interesting thing is that the Dominator robot moves the lever after it pushes the elevator. This makes the move back possible, because the lever is now not in the way of the mission model.
