Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.

Recap on the attachments, their purpose and how you should use them. 

How to control the arm of the push bot using the two triggers on the GamePad of the FTC Push Bot? 

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.

This is a video tutorial on accomplishing M12 and M13 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. We've decided to combine the two missions and approach M12 in a slightly different way - by activating a gear wheel and thus rotate the chicken. The mission is accomplished in almost no time and the result is flawless. The robot is Chain Monster, a powerful LEGO Education SPIKE Prime robot.

Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.

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 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.
