How to use the robot when the buttons are not accessible.
We start with the previous program where we made the robot move forward and turn. We continue in this tutorial with repeating the same RobotC instructions four times. Our goal is to make the robot move in a square.
In this lesson we build a simple LEGO Mindstorms NXT calculator program that sums, multiplies, subsctracts or divides two numbers between 1 and 50.
In this robotics tutorial, we give a few notes for the teacher about adding an axle to the front of the FTC robot and attaching a plastic plate to this axle to make the robot collect balls.
In this video, we introduce two pieces: beam with pins and the angular beam with pins
Display a matrix on the brick screen. Simple and easy. Download and run the program to see how
It all started with the famous 2017 mission for flipping a manhole and it was one of our favorite missions ever. Here in this tutorial we demonstrate the same principle of flipping a part from one side to the other. Sounds interesting, yes it is, yes it is.
In this video tutorial we continue the exploration of pinless attachments and how to add them and remove them in a quick fashion. We've done this for SPIKE Prime and for EV3 and we will provide some other references in the lesson in the course. The idea of an attachment below the robot is that sometime, during FIRST LEGO League competitions we have to bring a mission model from one place of the field to other. Basically push it.
In this video tutorial we accomplish the Basketball mission 10 out of 10 times. We use one of the more complex attachments for the FIRST LEGO League 2020 RePlay competition. You will see an learn how to successfully and consistently complete a mission that requires the robot to put a ball into a basket and lift the basket, or lift the basket and put the ball into it.
In the set for the Perfect Course, you have 3 different type of cables. They are called Breadboard Jumper Cables. We would need to use them to extend the default cables on the car and to connect the car components to our new controller
There are modifications that you must do on the FTC PushBot robot. Let's discuss them
By using the GamePad to control the arm with could lift it and return it back. The main problem with controlling the arm is that if you just use the motors you would hit the robot, bend the axles and breaks the gear wheels. We would use the distance sensor to make the arm move without hitting the robot.
Learn to program the Game of Life on the LEGO Mindstorms brick screen. This would require drawing on the brick screen, using blocks with switches and loops.
Following the Advance Sensor Calibration course section, we found the min and max values detected by each sensor. Now it is time for the real deal of the calibration. Detect the current value from the sensor and find what is the percentage of this value for the range between min and max.
How to add a plastic plate to the FIRST Technical Challenge Robot build with Tetrix. The plastic plate is for collecting the balls. The plate should rotate and should be connected to the axle.
With the last few videos, we entered the math world. Why we do it and what to keep in mind
This LEGO robotics video tutorial is a 10 out of 10 run of the one of the most complex missions at the FIRST LEGO League 2021 RePlay competition. As the mission has three parts we are measuring the success rate of each part of the mission. What you can learn from this tutorial is how to achieve three missions in a single run including line following and a lot of aligning
What is a single, and what is two degrees of freedom
How to construct an axle with a plastic plate connected to this axle and make this plate rotate and collect balls.
Let's cover the break at end option and learn why there is no lesson about it to students.
The previous tutorial showed you how to copy/paste instructions in RobotC. The current video will introduce you to loops.
In this video tutorial we demonstrate how the robot could accomplish the Power Switch mission. Power Switch consists of a cube with a lever and the lever should be rotate to 180 degrees. This mission model was very close to a FIRST LEGO League 2012 competition mission which was called - Oven. The robot, the attachment adn the mission model are built form a single LEGO Mindstorms Robot Inventor 51515 set and with the tutorial you will learn how to use an active attachment with 2 gear wheels to complete such missions.
This robotics video tutorial is about the FIRST LEGO League 2020 RePlay competition and how we accomplish the Slide mission with a LEGO Education SPIKE Prime robot. The goal of the Slide mission is to collect two LEGO Mini figures and bring them back to base. We are demonstrating a simple attachment that collects 2 figures placed in an add way. The whole attachment must bring one of the figures up and then back.
We've just plugged in the power bank in the Raspberry Pi controller. Has it started? Is it doing something? Why is it not moving? Simply put the raspberry power a small red diode and it just emits light. Well, it's on, but it will do nothing else.
In this robotics tutorial, we would discuss the length of the pipe and its dimensions. These are general considerations for every container on a FIRST Technical Challenge competition.
The code is already ready. It is attached below the video. Let's see how the program works and what it does and how to use it.
