Dot operator and importing commands
Have you noticed how the "start_at_power()" command is written after the "MotorPair()" command and they are separated by a dot? This dot separation is called a "Dot" operator.

Taking/Grabbing loops is one of the most common mission types at robotics competitions like FIRST LEGO League/World Robotics Olympiad. This tutorial is about an attachment that grabs the loop. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
With this video tutorial we demonstration the consistency and reliability of the using an intersection to position on the field. We move forward and we stop at the first intersection. We detect the intersection with a sensor. In the whole 10 runs there isn't a single mistake and you can see the precision of the robot on each run. Check it out and experiment with the same program for your robot.
Is it better to do fast turns or slow turns? Should you save some time by turning fast or should you be more precise by turning slow. Where is the balance? This video tutorial demonstrates exactly this for LEGO Education SPIKE Prime robot, their motion sensor and an ever occurring question on FIRST LEGO League competition which is how to find the balance and where is the balance.
How do you perceive the world? And how can a robot do it? Here is one of the ways!
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.
This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot. The attachment solves the light show mission using rubber bands! It works well, but it does depend on how new your model is. On newer models it can work with only 2 red rubber bands or even with 2 yellow and 2 red. Find the best combination for your field.
The trigger for the light show mechanism also releases Anna the Museum Curator and the masterpiece on the pedestal.
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.
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.
