In this video lesson I will show you how to follow a black line using just one sensor, but fast enough so that you could use it during any robotics competition without wasting any time.
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 :)
Showing the same run, but from a different angle. This allows you to see more of the way we sensors work and how exactly the robot positions itself.
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
We have previously aligned to lines with the Color Sensors. In this series we are doing the same program, but with Ultrasonic Sensors that are aligning the robot to a Wall.

"What is the light in the room?" - should it even matter. You can use one program for all lighting conditions by calibrating the color/light sensor of the LEGO Mindstorms EV3/NXT robots.
In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.
Implement a program for stopping at a black line with the blocks containing the implementation details for the InitArray, Calibration and Getting the calibrated result.
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.
This program uses the Move Steering block to controll the robot to move. Download and run the program.
Програми за робот, който може да се използва като банкомат, или като умна ключалка с цветен код. Програмите прибират и избутват цветната карта и изпълняват различни звуци ако реда на цветовете е верен. Ако реда на цветовете е грешен се чува звук за грешка.
Този робот е част от урок 7 в ниво 3.0 Сигурност и охранителни системи.
Developed with LEGO Education SPIKE App Word Blocks this program is used to accomplish the Drop mission model with a Drop attachment placed on Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions.
In this video tutorial we show how you can build robots that position on the field consistently and reliably by following and line and then aligning to a line. We also demonstrate the concept of "double align" which is quite powerful and even if there were some mistakes they will be handled.
In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. Make sure the line is big enough for the sensor to detect it and react to it. since we are measuring reflected light rather than the color of the line, we can and have implemented multiple states line following.
This program was intended for and tested on the Gazon robot
