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.
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.
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.
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.
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
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 topic of this tutorial is the purpose of a system of gears when throwing a ball.
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.
This is a 10 out of 10 tutorial that demonstrates the consistency and reliability of the robot to complete the Unused capacity mission. In this mission, we do not need any guidance to push the model as it is near the west side where it should arrive.
The dance mission is one of the most straightforward and easy missions to complete at the FIRST LEGO League competitions. This one is from RePLAY competition. The goal is to reach a specific place on the field and dance with the robot. You will see how we dance and have fun with our robot. Never forget to have fun during the competitions.
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.
The scorpion is one of the most famous robots build with the NXT kit. In this lesson we are showing how to use the rotation sensor to program the scorpion and its strikes. The main challenge is how to return the spike for the same amount of degrees after it strikes. The other topic is how to use variable to keep the state of the scorpion. Both of this techniques are very valuable during the competition.
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
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.
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.
In this video tutorial we follow a line 10 consecutive times. In this way we demonstrate whats the consistency that you could expect from the robot when following a line with a multi-states algorithm.
This is a 10 out of 10 video tutorial for the Slide mission at the FIRST LEGO League 2020 RePlay LEGO robotics competition. In the tutorial we demonstrate how to accomplish the mission 10 out of 10 times. At FLLCasts we try to build the attachments to be as consistent in their behavior as possible possible. In this way you know how the attachment along with the LEGO Education SPIKE Prime or LEGO Mindstorms robot will behave.
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.
