This video tutorial showcases how the Minibox accomplishes five missions - M02, M03, M04, M05, M14, and M15 - of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition.

It’s a rather complex run, as the robot uses multiple attachments and performs several actions. The MiniBox, a LEGO Education SPIKE Prime robot, is designed to leave its attachments on the mat after completing each mission. Take a close look at the attachments and study the program thoroughly before launching the robot!

This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever. 

This is a video tutorial that demonstrates how to accomplish M06 and M07 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster box robot which is a LEGO Education SPIKE Prime robot equipped with an active attachment with gear wheels, which engage the mission model’s gears to rotate the respective parts. The entire run takes less than 3 seconds, delivering a neat and precise performance.

In this video tutorial, the Chain Monster box robot accomplishes three missions in a single run from the FIRST LEGO League 2023-2024 MASTERPIECE Challenge season. The LEGO Education SPIKE Prime robot uses an active attachment to collect the mini figures, to push a lever, and to deliver the figures to their designated places. The robot starts from the red base and returns to the blue base, performing all these actions in less than 20 seconds - consistently and reliably.

In this video tutorial the Chain Monster box robot accomplishes a mission that requires two actions. We should lift up (lever) and push almost at the same time on the mission model for it to release the batteries. These mission model is from the FIRST LEGO League 2022-2023 SUPER POWERED competition.

This 10 out of 10 tutorial is a complete uncut recording and it shows how the Chain Monster box robot accomplishes 5 missions in a single run and it does this 10 out of 10 times. It is from the FIRST LEGO League 2022-2023 robotics competition.

In this video tutorial we accomplish 5 missions in a single run with the Chain Monster box robot. It accomplishes 5 missions from the FIRST LEGO League 2022-2023 robotics competition.

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.

In this video tutorial we look at programming the Kriket box robot to accomplish 5 missions. It is a long program for a long run that's why we are dedicating a separate tutorial. We are using LEGO Education SPIKE Prime Word Blocks app.

This 10 out of 10 tutorials is about consistency and reliability of the robot when accomplishing 5 missions in a row. We explore how we move between mission models. The programming is in the previous tutorial, here we look and discuss the behaviour of the robot

This tutorial demonstrates how we accomplish 5 missions in a row with a single robot and three attachments. This is a true multiple missions run for the FIRST LEGO League 2022-2023 SUPER POWERED. We Drop parts, we pull from the Smart grid, we push a lever, we collect a few energy units and we deliver the dinosaur toy.

This is a recording of a completely perfect, 10 out of 10 accomplishment of a two-part mission - Train tracks, from the FIRST LEGO League 2021-2022 Cargo Connect competition. Due to the proper use of motion and color/light sensors, the robot is 100% consistent and reliable for a non-trivial mission. Even when the robot makes a mistake, it auto-corrects and compensates for this mistake.

This tutorial explains the use of motion and light/color sensors to accomplish a complex mission split into three parts. It gets into detail about how we keep a straight line with the motion sensor, follow a line with the color sensors, and transition between different parts of the program by aligning and detecting lines with the sensor. The goal is to get to a reliable and consistent behavior of the robot. On top of that, it is configurable, as we've left a few parameters that could be set to configure the behavior for a specific robot, venue, lighting, battery level, and wheels friction.

Part four of the Catapult series is again about loading the catapult automatically but this time using EV3 brick, motor and sensor. We use a gear system with a medium complexity along with a "standard clutch" available in the LEGO Mindstorms EV3 kits. As a result, at the end of the video, the Catapult loads and fires automatically.

In this second video lesson on catapults we improve the stability of the base of the robot. An important feature of the new base is that it is not bending. Use the same principle in all of your constructions to achieve better, stronger robots.

Part three of the Catapult series is about loading the catapult automatically. We use a gear system with a medium complexity along with a very interesting "clutch" developed with parts entirely from the LEGO Mindstorms NXT kits. As a result, at the end of the video, the Catapult automatically loads and fires.

In this video we are solving part of the FIRST LEGO League Senior Solutions challange missions (FLL 2012) using LEGO Mindstorms NXT robots. I make a step by step explanation of each move I make. The goal of this video is to help you with ideas and suggestions on how one should look at the missions.

This is a 10 out of 10 video tutorial that demonstrates the consistency and reliability of the robot that accomplishes the Unlock Cargo Plane mission. The attachment is an active attachment with gear wheels. It has a single lever constructed from 2 beans and we use this attachment to push on the mission model.

This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.

In this video tutorial, we demonstrate how to release the cargo of a mission model. This mission model is an Airplane. We have to push a lever down to release it. We use an active attachment with a gear wheel.

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 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.
