Heavy lifting vertical from LEGO MINDSTORMS Robot Inventor, with building instructions
This is a heavy lifting attachment and it can lift mission models vertically. It is build entirely from LEGO MINDSTORMS Robot Inventor 51515 parts. This is one of the more complex and interesting attachments that we demonstrate in the course and it show how a few gear wheels and levers could be used to change the motion from circular to linear. This is powerful concept that could be very valuable during FIRST LEGO League competitions.

Active attachment for lifting from LEGO MINDSTORMS Robot Inventor, with building instructions
We use this attachment to demonstrate the principle of an active attachment. This is an attachment activated from the motor. It has one level attached to it. It could be reused. The attachment transfers power from the motor to the end of the lever and we can accomplish missions like the Power Switch mission from the FLLCasts Off-season mission models.

FIRST LEGO League with LEGO Mindstorms Robot Inventor. "Challenge" competition for 9-16 years old
The goal of this course is to take you through some of the most useful principles for building and using attachments to accomplish missions at FIRST LEGO League competitions. The whole course is based on a LEGO MINDSTORMS Robot Inventor and you need a single 51515 set and without additional parts (you will need a second color sensor for the lessons for using two color sensors, but feel free to skip them if you don't have it). For every mission there is a Scratch and Python program attachment. The course consists of 25 lessons suitable for beginner and advanced students. Every lessons consists of a video tutorial demonstrating the principle and how the mission could be accomplished along with building instructions for the robot, the attachment and programs for controlling the robot.

Improving FLL Robot Game. How to calculate gear ratio in complex systems
We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.

Multi-axles, many-directional LEGO Mindstorms mechanism for transferring power (almost a gear box). Part 1
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.

How to on Gears (part 1)
Gears could be a powerful tool for those who know how to use them appropriately. In this episode we introduce some of the basic terms and concepts behind using gears in your construction.

Active attachment for changing gears direction - part 2: improving durability
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.

Active attachment for changing gears direction - part 3: moving up&down
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.

Active attachment for changing gears orientation
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.

Multi-axles, many-directional LEGO Mindstorms mechanism. Worm Gears. Part 2
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.

Reusable geared active attachment for changing LEGO gears orientation
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.

Catapult built from LEGO Mindstorms EV3/NXT (Part 2 - Base)
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.

How to on Gears (Part 2)
In part 1 of How to on Gears tutorial I introduced you to the basics of the gear systems. Now we are going to examinate gear systems with more than two gears and take a look at cascade gear systems.

Catapult built from LEGO Mindstorms EV3/NXT(Part 4 - EV3 clutch and loading)
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.

How to use the Light/Color Sensors with the Catapult built from EV3/NXT
Vision is still one of the very few fields where a human being could outsmart a computer. Still. Colour/Light sensors are the cornerstones of implementing a smart LEGO Mindstorms robot that could at least partially do "vision". In this video tutorial, we are using the robotics sensor to detect loading and unloading of the catapult.

WRO Junior-High 2014. Sputnik. Collecting objects. Part 1
Starting with the World Robotics Olympiad 2014 Junior-High challenge we first catch the object on our path. We discuss a good mechanism for catching and lifting balls that can do two movements with one motor.
