You have the controller, you have the diode. The controller has a number of pins (holes). Where should you put the diode so that it starts blinking?
The small holes on the controller are called pins. On our controller we have 32 pins. The more pins that you have, the more elements you can controller with this microcontroller. For this video the interesting pins and 13 and GND
In episode 11 we looked at one of the most important topics for the competition - calibrating the light sensors. In this video I would like to show you how to use a more programmatic approach. This means letting the robot do the calibration on its own. Automatically.
As an exercise try to implement the calibration of the minimum and maximum values for a single sensor.
Implement the program for array initialization.
Follow the video tutorials for initializing arrays and implement the program.
In this tutorial, we connect the Motorola phones to the Tetrix controller using the USB hub.
An interesting question that has arise is whether we can use the LEGO Mindstorms EV3-G Software to program the NXT brick. In this episode we will go through the blocks from the EV3-G Software and see which works with the NXT Hardware and which does not.
One of the easiest ways to improve the accuracy of LEGO Education SPIKE Prime robots is to use acceleration and deceleration when moving. This also applies to LEGO Mindstorms EV3 and LEGO Mindstorms Robot Inventor and generally to most robots that we know of. This tutorial demonstrates how acceleration and deceleration could be used and what improvement in accuracy and consistency you could expect. This is quite useful for FIRST LEGO League and other robotics competitions.
In this video tutorial we explore acceleration and deceleration and how to make the robot turn precisely by using acceleration and deceleration. The goal is for us to demonstrate a program that turns the robot to 90 degree. In the first 45 the robot is accelerating and in the second 45 it is decelerating.
In this video tutorial we start with the basic of the basic, eg. how to move. We use the block from LEGO Education SPIKE Prime Word Blocks software. It is based on Scratch. The goal of the tutorial is to demonstrate how we can move and to teach something very important - the robot moves inaccurately
An advanced but understandable description of how to program the mindstorm robot to move in a regular n-gon like pentagon, hexagon etc. (Yes, we know math). We have also included notes on the used formulas. A must see for each of you who would like to master the robot movements.
How to control the arm of the push bot using the two triggers on the GamePad of the FTC Push Bot?
The comunication between the motors and the controller should be configured in the RobotC software. Each motor could be connected on a different port and the goal of the video is to show you how.
The last thing you want to lose during every robotics competition is time for changing the programs on the brick. This could require seconds and as we all know every second counts. There are a few ways to improve the way of choosing programs. In this video lesson we will show you how to program a menu directly in your program.
Conenct the motors of the VEX EDR motor to the VEX Corted Controller. For connecting we need the motor drivers.
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.
There are basically three type of generations in the robotics game of life.
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.
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 tutorial we use the LEGO Education SPIKE Prime Motion Sensor to reach a mission model on the field. It's a basic use of the motion sensor that we will extend in the next few tutorials and in the same time we take the opportunity to demonstrate what a MyBlock is and how to develop one. As a result of this video you will learn how to make the program easier to read and maintain by organizing the blocks in the program in special MyBlocks that couple them all together.
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.
Is it better to do fast turns or slow turns? Should you save some time by turning fast or should you be more precise by turning slow. Where is the balance? This video tutorial demonstrates exactly this for LEGO Education SPIKE Prime robot, their motion sensor and an ever occurring question on FIRST LEGO League competition which is how to find the balance and where is the balance.
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.
This LEGO Education SPIKE Prime video tutorial demonstrates the difference in turning slow and turning fast and using the Motion sensor to understand the orientation of the robot. We do 10 consecutive runs. The goal is to understand what can you expect from the robot behavior in terms of consistency.
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.
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")
