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 aim is to complete 10 out of 10 flawless retrievals, with the robot successfully latching onto the vessel and pulling it back to base every single time.
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.
Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.
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). In this series of test runs, our goal is to achieve 10 out of 10 successful attempts, meaning the robot completes all three missions flawlessly in every trial.
The robot uses a pinless attachment with locking beams for stability, enabling it to push the shark into its habitat, trigger a drop wall to catch the Krill, and lower a motorized arm with rubber parts to grab the Trident. This efficient approach ensures consistent results across the attempts while maintaining stability and precision throughout the runs. You can watch the full explaining tutorial here.
This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended.
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 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.
Need to transfer circular into a linear motion. You need a rack. Here is an attachment with a rack for our box robot.
Based on feedback from many of you in this episode I would like to show you how to build an active attachment that changes the orientation of a gear wheel placed vertically to a gear wheel placed horizontally. This attachment could be used in competitions and shows a basic principle of changing the orientation. All attachments could follow the same principle.
This is a very interesting idea that is worth sharing with the rest of the teams and the ELM team has provided it to us. Check out how they drop a LEGO human at a specific place.
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.
The attachment builds on previous episodes this time using two LEGO rubber bands. When a lever is released the rubber band exerts pressure on it and moves it in a circular motion. As an example we are solving the 2012 FIRST LEGO League, Senior Solutions, stove mission (which was quite interesting as a mission)
Each year the FIRST LEGO League robotics Competition involves loops. In this video tutorial I will go through the most common way of taking loops, show its disadvantages and suggest another way to do it.
In this video we are also focusing on lifting a loop as a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. We demonstrated an attachment for lifting a loop. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This is one of the very interesting attachments by the ELM team. It is using rubber bands and some rubber to precisely drop the chicken. Very interesting way. Check it out and try to learn from it.
In this video lesson I am building a LEGO Mindstorms EV3 active attachment powered by a small gear wheel. The attachment could move up and down, it is very useful for collecting objects. It could easily be adapted and used on other robots.
We are making a parallel with Video Lesson 56 from the series and we are also showing ways to improve the stability of an axle which is most of the time neglected, but could lead to great problems.
In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.
In this tutorial we demonstrate how a loops mission could be accomplished with a Push/Pull Attachment. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This video is about a lever that should be pushed and this lever is connected to an axle. This means the lever should rotate. It is a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. The inspiration for this mission is the FLL 2012 Senior Solutions Oven mission. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition.
Recap on the attachments, their purpose and how you should use them.
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.
In this video we discuss part of the pinless attachments build by the ELM team. Without pinless attachment it is nearly impossible to achieve a good score at the FIRST LEGO League competition.
In this episode we continue from Episode 55 and we improve the durability and stability of the attachment for a LEGO Mindstorms EV3 robot. Many times attachments are not very stable which results in gaps between parts. The goal of the video is to give basic construction ideas.
Rubber bands can be quite powerful. Based on several requests from you we are starting a series on using the LEGO Rubber bands available in the Mindstorms set.
This one is very special- an attachment that could lock itself on purpose while working.
