Video tutorials

Following the previous tutorials from the course, implement the calibration of the minimum and maximum values. 

There are basically three type of generations in the robotics game of life.

Conenct the motors of the VEX EDR motor to the VEX Corted Controller. For connecting we need the motor drivers. 

One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.

How to control the arm of the push bot using the two triggers on the GamePad of the FTC Push Bot? 

Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.

After we've download the software we must install it and most importantly configure it. Without propertly configuring the software it would be difficult to use the Cortex Controller.

Let's look at what game of life actually is, what are the rules and how to play the game on paper

A common question is how to display arrays on the LEGO Mindstorms EV3 brick screen. Displaying values from an array is not different from any other display operation. In this tutorial, we would look at displaying two specific values. The minimum and the maximum for a specific sensor from the Advance Calibration Course Section

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.

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

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 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.

With this video tutorial, we start with Turns with the VEX EDR robot. 

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. 

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.

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 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.

In this episode we combine in a single program the previous two programs for moving forward and backward. 

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

Spinning with the VEX EDR robot involves the use of both motors. The left and the right. Every robot with wheels could spin and this makes not exceptions.

The next important step when turning with a robot is to learn how to do an Arc turn.

Where is the math while turning? Is there any math involved? Should there be?

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 tutorial, we would build a simple program for controlling the Tetrix robot motors with the GamePads. We use the stick and when the stick is pushed forward the motors move forward. When it is pushed backwards the robot moves backwards.
