In this video tutorial we demonstrate a Grab attachment build from LEGO Mindstorms Robot Inventor 51515 set. The goal of the grab attachment is to accomplish the mission of bringing loops back to base without loosing or dropping them when returning. The principle of the grab attachment also demonstrates how to have a a locking mechanism. In this way there is not way to the loop to escape.

Grap attachments and loops
Loops in general are part of a FIRST LEGO League mission almost every year. In fact we don't know of competitions that do not involve loops. Because of this it is important to have in your toolbox a number of principles to accomplish missions involving loops. Attachments like the demonstrate here are especially for this.
How to use this tutorial
Build the robot, build the attachment and build the mission model. Download the programs and accomplish the mission. Build an attachment following the same principles but without following the instructions. Build a different attachment. Build an attachment for two for loops.

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.

Taking Loops with Grab Attachments
This animation demonstrates the use of a Grab Attachment build from LEGO Mindstorms Robot Inventor 51515 set. Many of the FIRST LEGO League missions could be accomplished by grabbing the mission model and the principles shown here is useful for mission models that look like a loop
