In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab.
This is not the standard video lesson. We have always wanted to just destroy the field and see how easy it would be. We would prepare a detailed lesson in the next few months, but this was one of the first tries on completely destroying the FIRST LEGO League Seniour Solutions field.
With this video tutorial we start the course for LEGO MINDSTORMS Robot Inventor and how to successfully program the robot for FIRST LEGO League robotics competition. It is good to have SPIKE Prime or EV3 for the competition. But if you happen to have Robot Inventor, don't be discourage. It is still possible to participate and accomplish a lot with the set.
The challenge for this video is to program a menu that is controlled from the LEGO Mindstorms EV3 brick screen.
One of the very common problems with the LEGO Mindstorms and LEGO Technic Gear wheels is then a tooth is skipped. In this video, I would like us to discuss this challenge and how do we solve it.
We will cover the names and the basic usage of the parts in our typical robot.
Answering three questions:
Why - because we believe any student and basically anybody must have a basic understanding of how electronic works. This course gives us the chance to present it and to move forward to better and smarter robots.
How - we do videos, we set tasks. You solve them.
What - we are using Arduino. Because it is popular, it is easy and we like it.
How to organize the different robots and group of students when working on lifting the robot.
After we take each sample, we perform calculations and these calculations could take different time. It is important to know how much time does it take to perform the calculations. In this video tutorial, we would data log the time and plot the data.
We will demonstrate the common mistakes students make when building a robot.
In this video tutorial we demonstrate the classic algorithm for following a line with robots. It is widely used in FIRST LEGO League competition and could be applied to LEGO Education SPIKE Prime and to other robots also. The algorithm follows a line by moving to the left and to the right and trying to stay at the edge of a black line.
This second way of positioning the LEGO Mindstorms EV3 motors on the robot leaves more space for the Mindstorms brick and for attaching a third motor. We are experimenting and showing the advantages and disadvantages of this particular construction.
We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.
Overview of what is going to happen in module 3
There are a few things that you should be careful about when building from instructions .
In this video tutorial we would discuss the M13. OBSERVATORY mission from the FIRST LEGO League robotics competition 2018-2019 Into Orbit. This is an easy mission. You can accomplish it by pushing the level with the robot. The challenge is that there is not enough space to move with the robot around the attachment. Let's discuss how we could achieve it.
Let's implement a more advanced program for this robot to learn how to use with motors in opposite directions - and this is to implement the Proportional Line Following algorithm.
This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.
This video tutorial demonstrates the accuracy and consistency of the robot behavior when we use only the blocks for moving the robot without any sensor. Spoiler alert - the robot is not consistent and it is not accurate.
We would see how both satellites work together on the World Robotics Olympiad competition. They must both follow different orbits and must cooperate for the mission to be accomplished.
Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.
Unplug one of the cables and observe what the robot does.
We will cover three ways to transfer your program from the computer to the robot.
Now that you have tried and solved a challenge involving a series of instructions, we would like to share a few best practices.
Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.
When organizing this course, the behavior expectations should be set at the very beginning of the course.
Now we have to program the robot. The steps that we will cover are starting the software, writing a program and downloading it to the robot.
