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.
We use a sensor so the robot must be reliable and accurate right? Wrong. The robot is not reliable and accurate only because we use sensors and that's really important during FIRST LEGO League competition. There is a reason for this and in this tutorial we demonstrate and explain how the robot behaves with a basic use of the Motion Sensor to move straight. As a result you will learn why is it important not to stop at this stage and to go to the next level with more advance use of sensors.
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.
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.
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?
When you first start the EV3 brick, you see the recent programs menu. Let's see what it is all about.
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.
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.
A special fourth case for a turning with robots with two wheels.
Now that we know how to make the robot move forward let's see we can make it move backward.
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
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.
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.
Unpacking the VEX EDR set and learning the names of the different parts included in the set
This is a video tutorial that demonstrates how to accomplish M06 and M07 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster box robot which is a LEGO Education SPIKE Prime robot equipped with an active attachment with gear wheels, which engage the mission model’s gears to rotate the respective parts. The entire run takes less than 3 seconds, delivering a neat and precise performance.
This video tutorial shows how the LEGO Mindstorms EV3 Rider Robot Motorcycle with Cart robot works. You can ride a friend with you.
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 is a video tutorial on accomplishing M12 and M13 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. We've decided to combine the two missions and approach M12 in a slightly different way - by activating a gear wheel and thus rotate the chicken. The mission is accomplished in almost no time and the result is flawless. The robot is Chain Monster, a powerful LEGO Education SPIKE Prime robot.
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.
Using Display, Sound, Wait and Move blocks together.
With this video tutorial, we start with Turns with the VEX EDR robot.
In this video tutorial we deliver the Innovation project model from base to the cargo connect marker on the field. The goal of the mission is to deliver. The mission model is assembled before that.
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.
Note for the teacher on making the construction more stable, more durable and using beams for this.
