Let's move with the VEX EDR robot using its motors, the wheels and some RobotC programming. We devide the program in three parts - Connect the motors, program the controller and turning.
Задачата е да програмирате робота да се движи напред и назад с все по-малки разстояния.
Програмирайте робота да се придвижи 50 см напред.
Нарочно откачете един от кабелите и наблюдавайте, какво ще направи робота.
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.
Във видеото можете да видите как да свържете правилно и надеждно брика с двигателите.
Направете сами, коригирайте грешките в конструкцията на EasyBot-а.
Overview of what is going to happen in module 3
По време на този курс ще работите с други ученици в една група. Те могат да бъдат ваши съученици, съотборници или ученици, които познавате от други извънкласни дейности. Важно е да познавате цялата група, за да можете да работите заедно по най-добрия начин.
Turning with the Gyro Sensor on a specified angle and stopping there have never been easy. It is not going to get any better. However, this is not a problem of the Gyro sensor. The problem is in the way we develop our programs.
The Gyro sensor in LEGO Mindstorms EV3 sets is new for the sets and we answer basic questions about its usage. The sensor detect when the whole constructions turns at a particular angle, but there are a number of gotchas in using it.
The EV3 Gyro sensor is quite powerful, but there are some little tricks when using it. In the previous episode we showed a hardware solution to the problem and now we are exploring how could the sensor be calibrated from the EV3-G software. Thanks to Sharon and Faye (full names omitted) for the request for this video.
The robot uses one middle motor. This middle motor with the use of a few gear systems controls for different axsels. We have attached wheels on this axles so it is very easy to extend the robot construction for additional LEGO Mindstorms active attachments
The course is very suitable for students and you don't have to buy a new set for each student. You can group them, divide them, organize the use of the sets and you could technically work with 70-80 student with only 6 sets.
Time to experiment with the controller, the diode and the program that makes the diode blink. Don't be afraid to change the program. We've prepared a number of tasks for you in the course that you should definitely complete before moving forward.
Arduino programs are developed with a software and this software is downloaded from the http://arduino.cc site.
Developing a program for the Arduino is very easy. We need to do again three thigs:
It is a hardware/software related course. You need a set with parts. And you need a number of sets for a class of students. You can buy the set from us, from other vendors, from online retailers. It doesn`t matter actually as long as you have the needed parts for the course. We have tried to create a very lean set, but if you can afford to buy additional parts you could create more complex and probably more interesting devices.
The course is designed for classes of students, but it could also be used personally. Each module should take you about 20 minutes and depending on how long your student hours are and how much time you will leave the students to experiment and solve tasks you could include different numbers of modules in your class.
This is a course for beginners, but the tasks would be interesting and for more intermediate students. We do not expect any previous knowledge from you except for how to divide numbers and use a computer.
Answering three questions:
Why - because we believe any student and basically anybody must have a basic understanding of how electronic works. This course gives us the chance to present it and to move forward to better and smarter robots.
How - we do videos, we set tasks. You solve them.
What - we are using Arduino. Because it is popular, it is easy and we like it.
Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features.
In this episode we do a full run of the mission for collecting a single treasure before going into explanation on how we have programmed the robot.
It's a box! It's a robot! It's a box robot. Box robots are very popular on different robotics competitions involving LEGO Mindstorms like the FIRST LEGO League or World Robotics Olympiad. Let's start with a brief introduction and continue in the next videos with explanation on the features of the robot and why such robots are frequently used.
We are working on the World Robotics Olympiad (WRO) 2013 competition and its elementary part. The series will introduce three different concepts and this would be Arrays, Menus and Counting different lines. In the video you will see the robot working as it is in the final stage.
In this series we will do a short demonstration on the FIRST LEGO League Trash Trek 2015 solutions by one of the teams. These are example solutions with good tips and tricks along with some interesting strategies and videos directly from the team
