LEGO MINDSTORMS Robot Inventor Programming for competition with Word Blocks

To successfully advance at competitions we need to understand two concepts - how to reliably and consistently navigate the field and position the robot exactly where we need it to be on every run, and how to build attachments that would accomplish a mission model once we have reached it. This course is focused on the first part. The second part is the whole FLLCasts platform, but start at FIRST LEGO League with LEGO Mindstorms Robot Inventor. "Challenge" competition for 9-16 years old.

The goal of this course is to help you learn to program LEGO Robots using Scratch and make them behave consistently and reliably during competitions. As a language we use LEGO MINDSTORMS App Word Blocks which is based on Scratch. We look at a lot of concepts that could be used for FIRST LEGO League and World Robot Olympiad competitions - for example, how to follow a line fast, slow, in a smooth way, with 5 states. Also, how to align to lines, how to do double align, how to keep a straight line with a motion sensor.

Unfortunately, LEGO discontinued the robot series during the making of this course which is why it's kind of shortish. You could use the SPIKE Prime course for a more in-depth analysis.

FLL 2020: 10 out of 10 on how to accomplish the Boccia Share mission with LEGO Mindstorms Robot Inventor

This is a 10 out of 10 tutorial where we demonstrate a reproducible completion of a shared mission. The mission is shared as both teams must agree about how they are completing the mission. The tutorials shows the robot approaching the FIRST LEGO League mission model. You will see how the robot pushes on the lever every time for a 10 out of 10 completion.

How a Lift attachment accomplishes a loops mission. Demo with Gazon 2.0 Robot from LEGO MINDSTORMS Robot Inventor

In this video tutorial we demonstrate a robot attachment that could be used to lift loops and other objects. Almost every year there is a mission at FIRST LEGO League competitions that involve lifting and the principle is interesting. You can build the attachment, robot and mission model from a single LEGO MINDSTORMS Robot Inventor 51515 set and learn a principle of building an attachment for lifting.

Tricky - Kick the ball attachment from LEGO Mindstorms Robot Inventor

The name of the game? Football!

This Kick the ball attachment for Tricky - the Mindstorms 51515 Robot Inventor smallest robot - is one of our favorites. Imagine a LEGO robot playing football. It is dribbling through the center of the field, it enters the box, it strikes and... goooooooal. What a fun game to play at home, if you decide to build Tricky with this kicking attachment. Aptly named for it’s “trick shots” with the included Mindstorms/Duplo ball. After you're ready with the construction of this robot, you'll find the instructions for building the goal frame below.

You can find the LEGO set, with which this was built, by following this link.

Chain Reaction from LEGO Mindstorms Robot Inventor

You know those constructions that you need to push or pull something and you get a cool chain reaction, right? Here are the building instructions of such a Chain Reaction built with LEGO Mindstorms 51515 Robot Inventor set. This construction was created to be used with the smallest Inventor robot Tricky and its Kick the ball attachment. The goal is to program the robot to kick the Mindstorms/Duplo ball, included in the set, so that the ball could push the lever and start the chain reaction.

You can find the LEGO set, with which this was built, by following this link.

Heavy lifting circular attachment from LEGO MINDSTORMS Robot Inventor, with building instructions

An attachment designed for Heavy lifting. It's build with LEGO MINDSTORMS Robot Inventor 51515 and it has a gear wheels mechanism that allows you to increase the torque and lift really heavy things. Build the attachment and check out the tutorial. This will teach you one more principle that you could use for FIRST LEGO League competitions.

Top attachment from LEGO MINDSTORMS Robot Inventor, with building instructions

This is an attachment for the top of the robot and the attachment is used for lifting different parts. It is reusable as we could change the lever and use the attachment for a number of different missions.
