We are programming this strange construction to move in a square. This is a basic task, but it is worth doing for a robot with motors placed in different directions.
Each palette contains programming blocks that share common purpose. We will cover most of them
Този проект работи с робота Хронос - ЛЕГО Майндстормс EV3 робот часовник. Той кара стрелките на часовника да започнат да се движат така, както биха се движили на истински часовник. В проекта има две програми: една за управление на стрелките за часове и минути, и друга за управление на стрелките за секунди и минути.
Този проект работи с робота Хронос - ЛЕГО Майндстормс EV3 робот часовник. Той има за цел да ви научи да разчитате часовника, като показва произволно време и ви дава 5 секунди да познаете какво е то. След това ви показва правилния отговор и се връща в начална позиция.
The Gyro sensor can be positioned horizontally, vertically or at a random angle. Have you ever wonder what does the gyro detect when it is positioned vertically. This is the subject of this video tutorial for the LEGO Mindstorms EV3 Gyro Sensor.
Robot tasks to exercize how to position on the field using only motors. STEM classes could use it to demonstrate mechanical imperfections in constructions and how important using sensors in this LEGO Mindstorms Robotics sets is
Use the color sensor to count the lines and stop on the third line. We do not use the wait block for this.
Last part of the series. The final touch of the program makes sure that it works and is following the line with the LEGO Mindstorms EV3 Color Sensor in a smooth and fast way.
The challenge for this video is to program a menu that is controlled from the LEGO Mindstorms EV3 brick screen.
EV3-G program for precise motor control of the LEGO Mindstorms EV3 robots
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.
Let's explain the problem of just waiting for the Gyro sensor to detect an angle and think of why the robotics systems work like that.
We extract the Proportional Line Following algorithm into a new block with parameters. This allows us to experiment with the Threshold, Constant Speed and Relaxation Coefficient. You can now easily use the block in you other programs without having to implement it.
This is the LEGO Mindstorms Education EV3-G software that was available from LEGO until October 2020. It is the version for Windows that is not Electron based and not Scratch based. It had all the good features that LEGO decided to drop and make things "easier" for students and slowly migrate to Scratch. LEGO decided to stop the Mindstorms EV3-G software and they are now (as of October 2020) distributing new versions of EV3-G. They decision affected a lot of schools. The new software is running only on Window 10 and there are lots of schools and teams using and relying on Window 7. We are preserving the version here for teams and students to use.
We can offer no support what's so ever for this version and we are asking LEGO if they are OK with us hosting this version publicly and making it available. Hope they would allow us.
Tasks for the Gyro sensor that you can use in STEM classes, while preparing for a competition or just to explore how the sensor works.
