Accuracy and consistency is the topic of this tutorial, as all 10 out of 10 tutorials are at FLLCasts. We use a robot build only from LEGO Mindstorms Robot Inventor parts and we accomplish the mission 10 out of 10 times. You will see how we use an active gear attachment to catch the wheel and pull it to the black circle, which accomplishes the mission
This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.
10 out of 10 tutorials for the Slide mission was a challenge. There were a lot of glitches with different attachments that we built. At the end we have an attachment that is able to reliably pull the mini figures up, then forward,then down which.
This video tutorial demonstrated the use of an active gear attachment for catching a wheel and pulling it. This is how we accomplish the Rowing Mission from the FIRST LEGO League 2021 competition. What you will learn is how such an attachment works. How you transfer power from the top of the robot where the motors are to the bottom of the robot where the catching mechanism is. Check out the building instructions for the attachment.
The Slide mission the FIRST LEGO League 2020 is about the LEGO Minifigures sliding down the slide and the robot bringing them back to base. We must somehow bring then back do base. Do we push them on the Slide? Do we pull them? Or we could lift them. In this video tutorial we decided to pull the minifigures, but there is a catch.
In this video tutorial we accomplish the Pull-Up bar mission from the FIRST LEGO League 2020. This is a 10 out of 10 tutorial for demonstrating the accuracy of the robot and the attachment. What you will learn is how a two part attachment works.
The goal of the Pull-Up bar mission is to have the robot pull up on the bar... ok.. wording. In this video tutorial we demonstrate an interesting attachment that helps the robot attach to the Pull-Up bar and hang there. How do we do this - with a platform, that brings the robot to the bar and then detaches itself from the robot
