• Attachments

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.

In this video tutorial we use an active attachment with a gears, built only form LEGO Mindstorms Robot Inventor parts, to accomplish the FIRST LEGO League 2020 Treadmill mission. The goal of the mission is to rotate the mission model for a couple of seconds so that a pointer makes a half circle rotation. What you will learn is a good principle to approach such missions.

This is a 10 out of 10 tutorial demonstrating the accuracy of an active gear attachment that accomplishes the Treadmill mission from the FIRST LEGO League 2020 RePlay competition. When the robot is well aligned to the line before that it is easy for the robot to accomplish the mission. You will see how we make use of the friction of the wheel to rotate the mission model.
