Video tutorials

This one is very special- an attachment that could lock itself on purpose while working. 

Present the details

In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.

In this video tutorial we look at Vertical Lift Attachments. The attachment, the root and the mission model are all build from LEGO MINDSTORMS Robot Inventor 51515 set. We've found that vertical lift attachments that could lift missions models vertically could be quite useful for FIRST LEGO League competitions. This attachment is one of the more complex attachments and some say it has an "eye opening" mechanism as you can learn so much from it. It uses gear wheels and two levers connected to those gear wheels to lift a part vertically.

This is a 10 out of 10 tutorial for a 3 missions run. The robot goes out of base and accomplishes 3 missions in a single run. It demonstrates the consistency and reliability of the robot and its program that uses sensors.

This 10 out of 10 tutorials is about consistency and reliability of the robot when accomplishing 5 missions in a row. We explore how we move between mission models. The programming is in the previous tutorial, here we look and discuss the behaviour of the robot

This is a programming video tutorials. It uses LEGO Education Word Blocks which is the scratch version. We enter into details of how to accomplish missions in a tight spot, how to align the robot and how to make it repeatable.

In this last part of the tutorial we actually lift the rocket modules and prepare them for lauch. First we have to collect them in the right order and them somehow lift them.

One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects. 

The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.  

Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets. 

If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"
