This is a live video tutorial of an inertia triggered attachment build with LEGO MINDSTORMS Robot Inventor. The attachment, the robot and the mission model are all built from a single 51515 set. The cool thing about inertia triggered attachments is that they are active and are activated without the use of any motors which means that you have the motors for the other missions at FIRST LEGO League competitions. In the tutorial we demonstrate and explain how such attachments works and how they could be used.

The physical phenomenon of Inertia is quite interesting. It is the way the universe works and Newton has formalized it in an easy to understand law of physics - the third law of physics is - "If a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force". The same applies here - when the robot stops the attachment will continue moving forward until it hits the ground.

FIRST LEGO League with LEGO Mindstorms Robot Inventor. "Challenge" competition for 9-16 years old
The goal of this course is to take you through some of the most useful principles for building and using attachments to accomplish missions at FIRST LEGO League competitions. The whole course is based on a LEGO MINDSTORMS Robot Inventor and you need a single 51515 set and without additional parts (you will need a second color sensor for the lessons for using two color sensors, but feel free to skip them if you don't have it). For every mission there is a Scratch and Python program attachment. The course consists of 25 lessons suitable for beginner and advanced students. Every lessons consists of a video tutorial demonstrating the principle and how the mission could be accomplished along with building instructions for the robot, the attachment and programs for controlling the robot.

Inertia triggered attachment for collect
This short animation demonstrates a really useful principle for FIRST LEGO League competition and this is how to use the Inertia of the robot to trigger an attachment that will do the work for us. It is very useful as we don't have to use the motors of the robot and we can afford to use the motors for other things.
