After several questions about the use of the LEGO Mindstorms NXT Light Sensor with the EV3 software, we have decided to go through this problem in this video tutorial and pay special attention to the Raw Sensor Value Block.
Tasks for introduction on building robots.
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.
We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles.
Смята се, че е очевидно и интуитивно как да свържем компютъра и робота. Все пак ще разкажем подробно как се прави, за да знаем, че е ясно на всички.
This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.
Next state in our state machine programming pattern is the "Turn Left" state and the corresponding behaviour.
Here we continue examining FLL 2014 World Class missions. We show different ways, for putting the insert in place as well as taking the loop from the robotics arm. Some of them are quite specific, which reminds us, that you need to think out of the box, while solving the missions.
Нарочно откачете един от кабелите и наблюдавайте, какво ще направи робота.
Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container.
Ще научим как да свързваме и да откачваме LEGO кабелите и в кои мотори трябва да свързваме двигателите.
One of the most interesting challenges in the series of FLL Competitions. Move a block and add additional floor on top of the block without damaging the construction. In this tutorial we would focus only this mission and we would achieve two movements with only one motor which makes the attachment quite powerful.
След като вече изпробвахте и се справихте с предизвикателство, включващо поредица от инструкции, искаме да ви представим някои добри практики.
90-градусовото завъртане на робота е различно от 90-градусовото завъртане на мотора!
Как да потърсим и намерим неизвестна стойност с възможно най-малко опити.
We will introduce a convention, an agreement, how and in which cases we are going to use each types of blocks.
Every turn is a circular motion and we will review the three types of turns from this point of view.
Време да приложим всичко научено досега на практика. Да направим робот шпионин!
Why we change the robots all the time and what to observe in each new robot.
Опитайте сами да поставите сензор за допир на робота.
The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.
