Why start with the phone set up in the Perfect STEM Course
Yes, we know. Starting with the phone when you have a toy car and a Raspberry Pi might seem strange, but this is why we do it.

Yes, we know. Starting with the phone when you have a toy car and a Raspberry Pi might seem strange, but this is why we do it.
In this tutorial, we show you how to display all the values from an EV3-G array on the EV3 brick display. We are using an array Read Operation along with a loop. We are also detecting the loop counter and using it as an index to an array. It's basically the only viable way to do it. The process is commonly referred to as - "Iteration over an array" (although we still do not have an iterator in the programming language, we promise that one day we would do the super advance videos on "iteration" using the LEGO MINDSTORMS robots")
In the EV3-G software, you could use negative numbers for power and rotations. In this episode, we would look at what is the meaning of this numbers and make a few notes of where the teacher must be more careful.
This video tutorial shows how the LEGO Mindstorms EV3 Rider Robot Motorcycle with Cart robot works. You can ride a friend with you.
The next challenge of the course is to build a container where you could store the balls (objects) that you are collecting. The first thing is to see how it works as an end result. You can use the same principle during FIRST Technical Challenge competitions. You can also fire the balls, just by rotating the axle in reverse.
With this video tutorial, we start with Turns with the VEX EDR robot.
In this video tutorial we will reach a specific location on the field 10 times. This programs demonstrates the accuracy and consistency of a program that used the Motion Sensor to detect the angle at which the robot rotates. At the end of the tutorial you will have a visual and clear picture of what you could expect from this basic usage in terms of consistency and accuracy. This might be enough for some cases and it might not be enough for others.
In the RobotC software we could make the robot wait for a couple of seconds by using the wait function. This will give the motors a chance to work and this will actually move the robot.
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M05. EXTRACTION, but compared to one of the other tutorials about this mission, in this specific tutorial we are using Box Robot 1 and a multi-purpose attachment. The attachment is designed for two missions and one of the missions is the Extraction
Note for the teacher on making the construction more stable, more durable and using beams for this.
It seems obvious and intuitive how to connect the robot and the computer. We must cover that part, so that we are sure you can download our programs to the robot later on.
The length of the lever has a certain effect when hitting the ball. In this tutorial, I would like to discuss what it's the effect.
How important is it to have predictable behavior in your classes.
Using Display, Sound, Wait and Move blocks together.
How to control the speed of the motors and the speed of the robot.
In this episode we combine in a single program the previous two programs for moving forward and backward.
In this tutorial, I will cover the adjustments of the display and the color lamp blocks from the LEGO Mindstorms NXT-G. Today I will show you how to use the color lamp in order to make your robot more interesting or how to display sensors values or try to draw something on the screen of the brick.
We are about to connect the whole car with the lights and motors to the controller. Let's recap to know what is ahead of us, what would the process be and what is the end result of the next couple of sections when at the end we have a car controlled by the phone
The tutorial is about what are the parts that you should buy to have the Ball Collecting mechanism.
Throwing/Shooting is a common challenge in FIRST LEGO League competitions and in this robotics video tutorial we are demonstrating an attachment that you can use to throw/shoot a ball. There have been missions for throwing balls like in bawling, or like in soccer/football. The attachment that we use relies on the properties of the plastics used for the LEGO MINDSTORMS Robot Inventor 51515 set - it bends and it throws.
In the course, we are going to use the following components and hardware elements. It is important to know their names and what are they used for.
The topic of this tutorial is the purpose of a system of gears when throwing a ball.
We are ready to build the first program for moving the robot forward and backward. We learn how to build simple programs for moving the program. But it is not that easy...downloading to the robot does not always result in the robot moving.
Parents generally use the same email address for their students. When enrolling into a group it is possible to enroll another user for the same email address. We call this a "brother or sister". Brothers and sisters could share the same email address but they have two different usernames.
The process of registering a brother or sister is the following
Why we change the robots all the time and what to observe in each new robot.
To prepare the robot to move in a square and to use a loop in the program we would first make this VEX EDR robot move forward and turn, using a program developed with RobotC.
To control the VEX Cortex controller we must use a software. In this episode we would download the software from the VEX site. Strange thing is that you must select your region correctly even if you are not in this region
