This is a teacher's note about the math behind calculating gear ratios with for our lifting attachment. It math model we build in previous tutorials is not exactly correct and here is the explanation why.

In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab. 

In this video lesson I will show you how to follow a black line using just one sensor, but fast enough so that you could use it during any robotics competition without wasting any time.

It has been a long road with the last 8 BigDaddy competition robots video tutorials, but we finally arrived at the Differential Lock. 

The third robot has the brick and motors placed vertically. This is quite unusual and difficult, but the construction is very powerful because it saves space.

We should how to build a frame that could hold the attachments for specific competition missions. This frame is added in a pinless manner. This means very fast and easy without any glitches of the pins.

Would you like to resolve all the problems with the light/color sensors that you have? And to make all of them work in a predictable, stable way even when using more than one MINDSTORMS colour sensors. 

When using Color sensors it is important to calibrate them depending on the light conditions in your venue. In this way, the calibrated sensor will show values between 0 and 100 independent of the light conditions. But using the default EV3 colour calibration available in the colour sensor block could lead to unpredicted problems that are difficult to track and resolved especially when used with multiple Color sensors. So in this series of tutorial we implement the calibration ourselves discussing the principles of colour sensor calibration.

The robot spins the rollers to move the pointer as far clockwise as possible.

The less often you interrupt the robot outside home, the more points you keep.

In this video we are also focusing on lifting a loop as a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. We demonstrated an attachment for lifting a loop. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

This video tutorial is part of the 10 out of 10 series at FLLCasts and we will demonstrate how to accomplish the FIRST LEGO League 2020 RePlay competition mission called Innovation Project. Our goal is to push the construction to the require place on the field. What you will learn with this tutorial is how to place a random construction in the base and push/pull it to a place on the field 10 out of 10 times.

With this animation we demonstrate an example for a quick pinless attachment that could be used to collect loops. Loops is one of the most common missions at FIRST LEGO League competitions. We use the LEGO Mindstorms Robot Inventor set to build the attachment, the mission model and the robot. They are all from the same attachment. In the live video in the same lesson we enter into more details about the attachment and we describe its idea
