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

In this video tutorial, we accomplish 3 missions from FIRST LEGO League 2022-2023 SUPER POWERED competition and we do it 10 out of 10 times. We successfully deliver the three objects to 2 different places on the mat. It is interesting that we have to carry the dinosaur toy from one side of the field to the other.

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.

In this episode we build a reusable attachment for a LEGO Mindstorms EV3 robot that changes gears orientation and direction. It is one of the most useful attachments that you could use to move levers up/down and right/left. Adding the attachment on the robot takes 2-3 seconds and shows a very useful general principle of how to build reusable attachments.

This is a 10 out of 10 tutorial for a 3 missions run. The robot goes out of base and accomplishes 3 missions in a single run. It demonstrates the consistency and reliability of the robot and its program that uses sensors.

In this video tutorial we accomplish 3 missions from the FIRST LEGO League 2022-2023 SUPER POWER robotics competition. The three missions are wind turbine, television, rechargeable battery. The robot uses a program with sensor compared to the previous way we've accomplished the missions with the same robot.

This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of the Kriket robot when accomplishing the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery.

In this video tutorial we accomplish the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery. We demonstrate how 3 missions could be accomplished in the single run and in the same time with a single attachment.

In this video tutorial, we demonstrate the accomplishment of three missions in a single run. The competition is FIRST LEGO League 2022/2023 SUPERPOWERED and the missions involve carrying and delivering a dinosaur toy, delivering energy units, and delivering the innovation project model.

This is the 10 out of 10 version of executing 3 missions in a single run. It worked like a charm! 10 times. We push and collect energy units for the FIRST LEGO League 2022-2023 SUPERPOWERED Challenge competition.

In this video tutorial, we accomplish three missions in a row. It is a little longer and more detailed tutorial, but hey, 3 missions, one after the other. These are the Wind Turbine, where we have to push 3-4 times and collect the energy units, the Watch Television, where we reach the mission model and slightly push, and, of course, the Rechargeable Battery - where we collect the energy units.

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.

The Load Cargo mission model could be accomplished by loading a cargo in a number of mission models on the FIRST LEGO League 2021-2022 Cargo Connect field. In this video tutorial, we load the cargo on the platooning trucks. In the previous one, we load it on the trains.

In this video tutorial, we demonstrate a reusable attachment. It is the same attachment we've previously used for two other missions. Sometimes we can build such attachments - one attachment that can complete several missions. Yes, the mission is similar - it is Load Cargo, but we are loading the cargo in different places on the field, and that's important.

This is a 10 out of 10 tutorial for a complex robot attachment that does a precise drop and is auto-correcting at the same time. It has decent consistency and reliability. We drop cargo onto the train and use a LEGO Education SPIKE Prime robot for this FIRST LEGO League 2021-2022 competition.

This is a precise drop tutorial where we demonstrate how to accomplish the FIRST LEGO League 2021-2022 Load Cargo mission that requires us to precisely drop a cargo into the drain. It is not an easy task, but it has a trick. A trick that allows us to 'shake' the cargo a little bit. The attachment is also auto-correcting to improve consistency. Use this principle whenever you need to drop things.

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. 

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.

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.

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.

Given the large number of gear wheels and axles in each EV3 and NXT sets there are many possibilities for building gear mechanisms. We are developing something like a gear box that has different axles that could all turn in different directions.

We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles. 

In this tutorial we would should you how to accomplish the FIRST LEGO League 2019-2020 Mission called Elevator. We are using the Whakatae - LEGO Education SPIKE Prime Competition Box robot
