Включване на EV3-G софтуер. Проекти и програми
Време е да програмираме робота. Стъпките, които ще разгледаме, са как се пуска софтуера за програмиране, как се пише програма и как тя се зарежда в робота.

Време е да програмираме робота. Стъпките, които ще разгледаме, са как се пуска софтуера за програмиране, как се пише програма и как тя се зарежда в робота.
This video tutorial demonstrates the accuracy and consistency of the robot behavior when we use only the blocks for moving the robot without any sensor. Spoiler alert - the robot is not consistent and it is not accurate.
In this video we are solving part of the FIRST LEGO League Senior Solutions challange missions (FLL 2012) using LEGO Mindstorms NXT robots. I make a step by step explanation of each move I make. The goal of this video is to help you with ideas and suggestions on how one should look at the missions.
In this video tutorial we would look at the mission run for M06. SPACE STATION MODULES. The missions is to precisely push a mission model into an opening. In almost any FIRST LEGO League competition there are such missions. The tutorial contains only the mission run on the field. We accomplish a single mission.
The robot works on the field and decodes the different colours that represent the rows and the columns.
Нещата, за които да внимавате като преподавател, докато учениците строят роботите си по инструкции.
We start with FIRST Technical Challenge and how you develop programs with the GamePads. It is up to you to decide how sticks, buttons and triggers from the GamePad will control the different motors of the robot and there are different decisions that you should make.
After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.
Сега ще направите първата си програма в курс и ще накарате робота да се движи напред.
If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.
This quick pinless attachment is designed for collecting parts by pushing them. It shows the principle of putting a robot of an attachment in a very fast manner. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
We explore some common mistakes when a program is developed and becomes complex. We then try to remove part of this complexity.
Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.
How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.
A human being walks with an average speed of about 5 km/h (3 miles/h). In this video tutorial we will develop a block for LEGO MINDSTORMS EV3, that measures the speed of the robot in distance/time units where time will be configurable and could be 1 second or 0.5 seconds or any other number of seconds you pass as a param to the block. Measuring the speed of the robot is very powerful if you start building an Artificial Inteligence for your robot and is quite fun :)
"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must.
In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block
Когато ние, преподавателите, пишем програми и проекти, те винаги имат говорещи имена. Сега ще ви покажем как да задавате готини имена и на вашите програми.
It this episode we would present you with our attachment for lifting the robot.
Нека да разгледаме брика - LEGO Mindstorms EV3 Intelligent Brick. Умната LEGO тухличка.
EV3 брикът е главният компютър на вашия робот. Той има екран, бутони и различни портове.
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units.
We would continue from the previous program where we used variables and we would change this to arrays.
We will introduce a convention, an agreement, how and in which cases we are going to use each types of blocks.
