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.
Sometimes the best final run is the one that does exactly one job. In this FLL 2025 UNEARTHED competition tutorial, the Smaller Pancake box robot uses the Site Marking attachment to carry the flag straight from base to its destination in under ten seconds.
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.
Sometimes the most effective solutions are also the most straightforward. In Mission 14: Forum from the FIRST LEGO League UNEARTHED season, the Smaller Pancake box robot uses a lightweight pinless attachment to deliver the collected artifacts safely into the scoring area.
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 run asks the robot to think several missions ahead. In the FLL 2025 UNEARTHED competition, the Smaller Pancake box robot crosses almost the entire field with a multi-purpose M14 and M15 attachment, places the Mission 15: Site Marking flag, collects the opposing team's minecart, and brings it with previously collected artifacts to the left base for Mission 14: Forum.
In this video tutorial, we demonstrate an attachment that is activated when we reach the mission model. That means the attachment is not activated by a motor but by the movement of the robot. We accomplish the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model, where we have to move and bring cargo to the mission model and leave the cargo there.
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.
Two neighboring missions become one efficient run in this FIRST LEGO League 2025-2026 UNEARTHED competition tutorial. The Smaller Pancake box robot carries the combined M05-M07 attachment to release the ore from Mission 6: Forge, raise Mission 5: Who Lived Here, and move the blocks toward the edge for later use.
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.
This is not the usual straight trip from base to mission model. For Mission 7: Heavy Lifting in the FLL UNEARTHED season, the Smaller Pancake box robot deliberately travels outside the mat, uses the table wall as a reference, and reaches the Millstone with an active pinless 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.
Rather than forcing the scale down, this solution lets gravity finish the job. In Mission 10: Tip the Scales from the FLL UNEARTHED season, the Smaller Pancake box robot uses a passive pinless attachment to lift the green cover just enough for the scale to tip, then catches the pan as it reverses.
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.
For Mission 11: Angler Artifacts in the FIRST LEGO League 2025-2026 UNEARTHED competition, the Smaller Pancake box robot does not simply drive into the model. With the geared Angler Artifacts attachment, it pivots into position, meshes with the mission gears, and raises both the flag and the artifact before heading toward the right base.
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.
One attachment, two mission models, and a lot happening in only a few seconds. During the FLL UNEARTHED season, the Smaller Pancake box robot uses the M02 and M03 attachment to reveal the map, secure the third topsoil section, and send the minecart to the opposing team's field.
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.
Four jobs are packed into one compact run for Mission 01: Surface Brushing in the FIRST LEGO League 2025-2026 UNEARTHED competition. The Smaller Pancake box robot uses the Surface Brushing attachment to settle against the model, clear both soil deposits, capture the brush, and return to base.
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.
Learn how to complete Mission 15: Site Marking and Mission 12: Salvage Operation in the FIRST LEGO League 2025-2026 UNEARTHED competition using the Smaller Pancake box robot and this passive attachment.
You think that you can quickly change the attachments of your LEGO Mindstorms EV3 competition robot? Are you sure? In this first episode of the series you will see how to create and attach attachments without using pins and how faster and easier this could be. You will see the design logic of a few attachments and how they work on the field.
Pinless attachments are smart and quick and could make a big differences between two robot constructions. In this video we are sharing a nice idea for a pinless attachment placed below the robot.
If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.
In this video tutorial, we demonstrate a full run for the FIRST LEGO League 2024-2025 SUBMERGED challenge, completing all missions in a single sequence. Each mission is shown individually beforehand, with close-up views of how the attachments work and the principles behind their design. All attachments are pinless, making them quick to change during the run, though aligning and loading the robot still requires practice. The strategy involves moving from one base to the other while accomplishing as many missions as possible, including retrying those close to base when needed.
While the complete run takes longer than the official 2.5 minutes, the focus here is on demonstrating reliability, consistency, and the trade-offs between time and scoring points. In some cases, missions are skipped to focus on higher-value tasks, but in this run, we aim to complete them all. The result is a strong performance that comes close to the maximum possible score.
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 solving M05, M09, collecting samples for M14, 3 Krill for M12, and Reef Segments for M03 of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using Nautiq box robot (a LEGO Education SPIKE Prime robot).
