To correctly upload the blinking diode program to the controller we must first check some of the configurations of software. These are the "selected controller" and COM port
In this video tutorial we are demonstrating the impact of slow and fast acceleration on the robot. In the Scratch program there is an acceleration block for fast and slow acceleration. The robot behaves in different way. Let's explore them so that you know what to use for FIRST LEGO League competitions.
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
In this episode of the Basic NXT Programming series I will cover the sound sensor. I will explain how to program the sound sensor, stop on common problems faced, when the sound sensor is used and finally we will build a program that will allow us to control the robot's speed through the volume of the sound.
In this video lesson, we will show you how to build a menu as a MyBlock in LEGO Mindstorms NXG-G. Having a menu is a must at robotics competitions since it saves time and gives easy access to program functionalities.
This lesson shows how you could use the rotation sensors of the motors of a LEGO MINDSTORMS NXT robot. This technique is very powerful during the competition. We give ideas on how to show the value of the sensor on the display, how to check if you have completed a given job or you are still doing it and other even more advanced topics. Understanding the rotation sensor is a must if you want to use the full capabilities of the motors.
Every electronics tutorial, book or course about Raspberry Pi or Arduino will use a motor driver. Very few of the courses will actually explain why do you need a Motor Driver, what is it for?
One of the very common tasks on different FIRST Technical Challenge competitions is to collect objects. In this case, these are colourful specifically shaped plastic object or in simple terms - balls.
Now that we know how to make the robot move forward let's see we can make it move backward.
When you first start the EV3 brick, you see the recent programs menu. Let's see what it is all about.
In this video tutorial, we demonstrate how to release the cargo of a mission model. This mission model is an Airplane. We have to push a lever down to release it. We use an active attachment with a gear wheel.
In this video tutorial we take a next step in programming reliable and consistent robots and this is to learn how to stop at a second intersection. We need this because most of the time when we want to reach a mission model on a robotics competition field, the model will be located away from us and we must use all kind of technique to reach it. In this tutorial - we stop at a second intersection.
Level 2 from "FLLCasts Certified VEX IQ Robot Driver - Class R1" certification path is to start on the border of the field, move through to the last obstacle, turn and return back to the first one. turn once again and go up to the second one, turn around one last time and sprint towards the finish line at the border of the field.
With the set for the course, you also have an SD card. It is important that you understand why and how is the SD Card is used.
A special fourth case for a turning with robots with two wheels.
Unpacking the VEX EDR set and learning the names of the different parts included in the set
One of the interesting things in this sequence of videos is the program. The program detects when the system has reached the maximum speed and then stops the motor from rotating. We detect this with the EV3-G software
This is a 10 out of 10 tutorial demonstrating the consistency and reliability of a LEGO Education SPIKE Prime robot when the robot delivers a mission model to a specific position on the field.
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.
For Level 3 from from "FLLCasts Certified VEX IQ Robot Driver - Class R1" certification path you need to slalom along the field. Start on the border of the field move forward until the first obstacle. Turn after it, continue forward, then turn around the second obstacle, continue forward and turn around the last obstacle. Again continue forward, turn around the second obstacle, continue straight around the first obstacle and sprint towards the finish line at the border of the field.
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.
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.
This video tutorial shows how the LEGO Mindstorms EV3 Rider Robot Motorcycle with Cart robot works. You can ride a friend with you.
