This video tutorial demonstrated the use of an active gear attachment for catching a wheel and pulling it. This is how we accomplish the Rowing Mission from the FIRST LEGO League 2021 competition. What you will learn is how such an attachment works. How you transfer power from the top of the robot where the motors are to the bottom of the robot where the catching mechanism is. Check out the building instructions for the attachment.

In this video tutorial, we push two of the mission models with a pinless active attachment with gears. The goal is to push the mission models after the blue lines. This attachment is interesting as it demonstrates a non-straightforward idea of how we can push the mission models. We explain the Scratch program and how we use the motion sensors - you will learn how to turn to a specific angle by using the motion sensor.

This is a 10 out of 10 tutorial demonstrating the accuracy of a Flip Attachment for the FIRST LEGO League 2020 Cell Phone Mission. The flip attachment flips a phone. Moves forward and flip it. This is a tricky business. It might not work. The trick is to approach the mission model from the right angle. In the tutorial you will see a demonstration and will learn how such a mission could be accomplished accurately with a LEGO Mindstorms Robot Inventor robot and attachment with gear wheels.
