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.

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.
In this LEGO video tutorial we accomplish 3 missions with the Kriket box robot. A number of actions are performed like Lever, Lift, Drop, Pull, Align. This tutorials shows how to accomplish missions models that are closely positioned next to each other.
This attachment is accomplishing three missions and partly one more mission from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot. It solve mission 6 - HYBRID CAR, mission 14 - TOY FACTORY and mission 15 - RECHARGEABLE BATTERY. It partially solves mission 2 - OIL PLATFORM.
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 M11 Sonar Discovery and 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 combined two-part attachment for maximum efficiency. The front section is designed to drop the krill into the Whale for M12, using a stationary beam to open the whale’s mouth and an angled beam to tip the krill container so they fall inside. Wheels are added as counterweights to prevent the container from opening during movement.
The rear section operates the sonar rotation for M11, using a chain-driven mechanism to transfer power from the robot to the mission model. A hooked beam is integrated at the end, allowing it to easily catch the yellow part of the sonar for rotation. This combined design allows the robot to complete both missions in one smooth, coordinated run without swapping attachments.
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.
