This is a 10 out of 10 tutorial on a basic approach for one of the unique challenges in FIRST LEGO League competitions. This basic approach to a solution is not very consistent, and in some of the next tutorials, we will present a new solution. But we decided to record it to demonstrate how reliable this attachment is when it comes to carrying large objects. That could give you ideas of things to avoid.

This is a 10 out of 10 tutorial for pushing gently on a mission model. We also discuss how to build robots that tolerate error and auto-correct their behavior.

In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.

This video tutorial focuses on accomplishing M01 Coral Nursery, M02 Shark, M03 Coral Reef, and M04 Scuba Diver of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a two-part pinless attachment designed to complete multiple missions in a single sequence. The small angled surface mounted under the robot flips the coral buds from M01 and pushes the shark from M02, while the front arm catches and delivers the Scuba Diver from the coral nursery to the coral reef support.

The back section of the attachment flips the coral reef from M03 using a friction-pin mechanism that stays straight during travel but drops the horizontal arm at the mission model to push the yellow plate and raise the coral reef. Extra axles on the front arm prevent the Scuba Diver from falling during delivery, ensuring reliable scoring. This coordinated multi-mission approach maximizes efficiency by combining pushing, collecting, and delivering into one smooth run.

This is a programming video tutorials. It uses LEGO Education Word Blocks which is the scratch version. We enter into details of how to accomplish missions in a tight spot, how to align the robot and how to make it repeatable.

This video tutorial is for the Tire Flip Mission from FIRST LEGO League 2020 RePlay robotics competition. Flip missions are always some of the most interesting and challenging. In this tutorial you would learn how to build an attachment and accomplish a mission that requires you to flip a part, like flipping a coin. Most of the complexity for this mission is in the attachment and not the programming, but this is also way it works perfectly, every single time.

In this video tutorial, we push two of the mission models with a pinless active attachment with gears. The goal is to push the mission models after the blue lines. This attachment is interesting as it demonstrates a non-straightforward idea of how we can push the mission models. We explain the Scratch program and how we use the motion sensors - you will learn how to turn to a specific angle by using the motion sensor.

This is a 10 out of 10 tutorial demonstrating the accuracy of an active gear attachment that accomplishes the Treadmill mission from the FIRST LEGO League 2020 RePlay competition. When the robot is well aligned to the line before that it is easy for the robot to accomplish the mission. You will see how we make use of the friction of the wheel to rotate the mission model.

In this video tutorial, we accomplish three missions in a row. It is a little longer and more detailed tutorial, but hey, 3 missions, one after the other. These are the Wind Turbine, where we have to push 3-4 times and collect the energy units, the Watch Television, where we reach the mission model and slightly push, and, of course, the Rechargeable Battery - where we collect the energy units.

This video tutorial focuses on accomplishing M02 Shark, collecting the trident for M14 Sample Collection, and collecting a Krill for M12 Feed the Whale of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless attachment with two locking beams for stability, featuring two main “chambers” and a motor-powered arm with rubber parts for handling multiple mission elements.

The left chamber is used to push the shark from M02 into its habitat, while the opposite side has a passive beam-trigger mechanism to drop a wall and catch the Krill in front of the shipwreck. The motorized arm slowly lowers to grab the Trident from the bottom using rubber parts, a solution that is not 100% reliable due to the challenge of the element but is the best tested option. The side locking beams are essential for keeping the attachment secured during these precise maneuvers, preventing it from detaching during the run.

This is a 10 out of 10 video tutorial that focuses on accomplishing M01 Coral Nursery, M02 Shark, M03 Coral Reef, and M04 Scuba Diver of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot).

The robot pushes the shark, flips the coral buds and coral reef, and collects and delivers the Scuba Diver with precision. This efficient multi-mission run is designed for speed and reliability, ensuring maximum points with minimal wasted movement. You can watch the full explaining tutorial here.

This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.

This video tutorial focuses on accomplishing M15 Research Vessel of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless attachment designed to push the ship loaded with cargo to its destination. After the previous run, the hook part is removed and replaced with a locking component that holds the ship securely during transport.

The locking mechanism uses friction pins to keep the ship stable until it reaches its destination, where it can then be released smoothly. This approach ensures the cargo remains secure throughout the journey while allowing for safe delivery and quick unloading at the final position.

In this video tutorial, we accomplish the FIRST LEGO League 2021-2022 mission called Platooning Trucks. The goal is to connect the two mission models (trucks) to each other and then connect them both to the bridge. It's quite an interesting mission as it involves three mission models.

In this video tutorial, we demonstrate one of the unique missions of the FIRST LEGO League competitions - we must carry a rather large object from base an leave it on the field. This takes some considerations as other missions must be accomplished before that.

This is a 10 out of 10 tutorial on an active, auto-correcting, locking, and aligning attachment that accomplishes the FIRST LEGO League 2021-2022 Cargo Connect Large Delivery mission. The difference, as compared to the previous solution to the mission, is that we now use a much more consistent and reliable robot.

This video tutorial focuses on taking the Research Vessel for M15 of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using Nautiq box robot (a LEGO Education SPIKE Prime robot).

This video tutorial focuses on accomplishing M15 Research Vessel of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless latched attachment mounted under the robot for maximum stability. The attachment features a hook that catches the research vessel and pulls it back to the launch area, after which the hook can be removed and the remaining parts reused for the next run.

Important: Before starting this run, ensure the part that locks the boat for the next run is raised; otherwise, the robot cannot hook the vessel correctly. This simple but effective mechanism allows for a quick and reliable retrieval, setting up the next sequence of missions without additional adjustments.

This video tutorial focuses on accomplishing M15 Research Vessel 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, with the robot pushing the loaded ship to its destination, releasing it cleanly, and moving to the other launch area without a single failed attempt.

The run uses a pinless attachment with a locking mechanism and friction pins to secure the cargo during movement and allow smooth release upon arrival. The precise programming and stable design ensure consistent performance across the trials.

This video tutorial focuses on accomplishing M06 Raise the Mast and M07 Kraken’s Treasure of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless attachment connected to the bottom of the robot, featuring side guides with stoppers for precise mast lifting and a central rubberized section to catch the treasure chest.

The challenge in this run is to collect the treasure before raising the mast fully, as the mission model locks the chest if the mast is lifted too far too soon. The robot must push and lift with great precision, stopping at exactly the right point to avoid triggering the lock, then continue raising the mast to complete the mission. This sequence demonstrates careful mechanical design, accurate programming, and precise timing to accomplish two interconnected missions in one smooth run.

“Doing the same with less” can save time and space.

We start with the first mission - trying to build attachments that are small and tidy and the Gazon robot allows us to do so. With a few pictures you can see how the robot should be placed along with all the attachments
