After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.
Now we will create the first program in this course and we will make the robot move forward.
We will demonstrate how to connect the brick and the motors by using cables correctly and reliably.
If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.
We explore some common mistakes when a program is developed and becomes complex. We then try to remove part of this complexity.
How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.
A human being walks with an average speed of about 5 km/h (3 miles/h). In this video tutorial we will develop a block for LEGO MINDSTORMS EV3, that measures the speed of the robot in distance/time units where time will be configurable and could be 1 second or 0.5 seconds or any other number of seconds you pass as a param to the block. Measuring the speed of the robot is very powerful if you start building an Artificial Inteligence for your robot and is quite fun :)
"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must.
In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block
Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.
When we, the teachers, make programs and projects, we give them descriptive names. Let's show you a way to put cool names on your programs.
It this episode we would present you with our attachment for lifting the robot.
Let's review the LEGO Mindstorms EV3 Intelligent Brick
The EV3 brick is the main computer of your LEGO robot and it has a display, a few buttons and various ports.
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units.
We would continue from the previous program where we used variables and we would change this to arrays.
We will introduce a convention, an agreement, how and in which cases we are going to use each types of blocks.
How to align the wheels and how much should you push for this solution?
Overview of what is going to happen that part of the lessons.
Let's learn how to use the Sound block.
What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.
We would look at the rules of the competition over our small model and we would start solving the field.
We will demonstrate an alternative way to make the robot move backward
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M04. CRATER CROSSING. These are some of the funniest missions at this robotics competition. Try to move over an obstacle with a robot and if you manage to return back to base without bumping into other mission models that would be great.
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
