Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot. 

How to align the wheels and how much should you push for this solution?

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

Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?

As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it. 

(we are releasing the video without explanations and will add the explanations later)

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. 

Accuracy and consistency is the topic of this tutorial, as all 10 out of 10 tutorials are at FLLCasts. We use a robot build only from LEGO Mindstorms Robot Inventor parts and we accomplish the mission 10 out of 10 times. You will see how we use an active gear attachment to catch the wheel and pull it to the black circle, which accomplishes the mission

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, 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.
