LEGO MINDSTORMS Robot Inventor

On every FIRST LEGO League competition and generally robotics competitions with LEGO robots, we build attachments to accomplish missions and we must accomplish the missions in a limited amount of time. Most of the time we can not accomplish the missions with a single attachment and we have to change attachments. This is where building robot attachments that are easy to remove really makes sense. In this tutorial we discuss some of the things that should be considered in the building Easy to Detach modules and attachments

This is an animation of a quick pinless attachment that is placed below the robot and is used to deliver parts, like the Container Mission model, to different parts of the field. In the live video in the lesson we explain more about the principles, while here in the animation you can get a quick overview of how it works and you can try to follow the same principles for an exercise.

This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.

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

In this video tutorial we demonstrate an attachment that can accomplish Drop missions. A drop mission is when you have to move on the FIRST LEGO League field with the robot, reach a mission model, and drop a part in this mission model. First time we saw such missions I think was in FLL 2013. The attachment, the robot and the mission model could be build from a single LEGO MINDSTORMS Robot Inventor 51515 set. The mechanism for dropping works by releasing a lever when the attachment is pushed against the mission model. Check them out.

In this video tutorial we demonstrate how the robot could accomplish the Power Switch mission. Power Switch consists of a cube with a lever and the lever should be rotate to 180 degrees. This mission model was very close to a FIRST LEGO League 2012 competition mission which was called - Oven. The robot, the attachment adn the mission model are built form a single LEGO Mindstorms Robot Inventor 51515 set and with the tutorial you will learn how to use an active attachment with 2 gear wheels to complete such missions.

This animation demonstrate the use of an LEGO MINDSTORMS Robot Inventor attachment to lift a lever of a mission model. The mission model is the Power Switch mission model where you have to move the lever from one side of the mission model to another. The principle of the attachment is powerful and easy to implement for all kinds of missions.

This animated video tutorial demonstrate the use of a lift attachment to accomplish loops mission. It is a lift attachment with a circular motion

This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.
