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 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.
This is a 10 out of 10 tutorial, where we demonstrate the consistency and reliability of an attachment activated when we reach the mission model. We do not use a motor. We activate the attachment by pushing the robot to the mission model of the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery Mission.
This is a 10 out of 10 tutorial where we deliver and drop precisely to complete a FIRST LEGO League 2021-2022 Cargo Connect mission. We reuse the same attachment as in other missions to demonstrate a reusable attachment.
In this video tutorial, the MiniBox robot accomplishes M08 and M09 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition.
The MiniBox, a LEGO Education SPIKE Prime box robot, uses a detachable attachment to release the camera down the track for M08 Rolling Camera. Then, with a slight turn, it pulls the M09 Movie Set boat model and positions it in its designated spot. Let's take a look!
In this video tutorial we demonstrate how to accomplish M03, M04, M14, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster which is a LEGO Education SPIKE Prime robot equipped with two pinless active attachments.
The side attachment uses a gear mechanism to press down a lever and drop the mini figures with loops. It has a more advanced construction with a special lock to prevent the attachment from rotating when mounting it on the robot. Pay attention that the lock should be removed before the start of the run.
We use a special construction to help us align the robot in the base to ensure the robot starts from the same place every time.
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 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.
In this video we discuss the durability of the construction of LEGO robots and how do we make them more durable.
In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.
The bench mission was one of the most difficult we've encountered, especially when it comes to accomplishing the mission reliably. The goal of the mission is to push the bench down, lift part of it and leave 4 boxes at specific places. The whole concept of the mission is awesome. Here is how we did it:
This video tutorial demonstrates an attachment that flips a mission model. The mission model is attached to the field, but it contains a lever. This lever must be flipped from one side to the other. There is a switch. We use a pinless active attachment with gear wheels, and you can see how this works in the tutorial. There is no use of sensors as we don't need them. We will leave the alignment and positioning for some other tutorials.
In this video tutorial, we demonstrate how to complete M12, M13, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. We use the MiniBox, a robot built from LEGO Education SPIKE Prime.
To complete the missions, the robot rotates the chicken to trigger the M12 Virtual Reality Artist, pushes the M13 Craft Creator to release the creation, and collects the M15 LEGO minifigure. After completing all tasks, the robot detaches its attachment and leaves it on the field for a faster change at the base. Let's take a look!
This video tutorial focuses on accomplishing M01 Coral Nursery and 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 uses a pinless motor-powered attachment specifically designed to raise the coral tree to the coral tree support while delivering reef segments outside the launch area. This attachment was chosen after testing multiple designs, and it proved to be one of the most reliable solutions for this task.
The motor-driven lifting mechanism is mounted using long axle pins due to the gearwheel’s position, and a heavy brick is added on top for extra sturdiness, preventing the attachment from popping off during operation. On the side, a simple holder secures the three reef segments collected in previous runs for easy delivery during this mission. This combination allows the robot to lift the coral tree smoothly, place it accurately, and complete the reef segment delivery in a single, well-coordinated sequence.
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.
