"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.
Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing.
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.
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
Move the robot using the Move Steering block. We explore what the different values for Steering mean and how to use them. We also explore how the motor is configured to run for a number of rotations or seconds and what is the difference.
We create a program for detecting when the Touch Sensor was Pressed/Released. Move until it is pressed, continue when it is released.
The way sensors and programs work in a robotics system is sometimes not-intuitive for a beginner, but nevertheless very logical. Building a program for a touch sensors for "Press->Go->Press->Stop" using the EV3-G software could be quite challenging at the beginning even for experienced teachers, students and robot builders.
Tasks for STEM classroom and home exercise to get you used to using the LEGO Mindstorms Touch sensor. Solve them, build a program, record a video and upload your solutions below.
The robot detects an object. After the object is remove we want to make the LEGO robot move forward.
Stop on detecting an object with the Ultrasonic sensor and move after detecting there is no object. Join of the previous two video tutorials in one
Follow an object using the LEGO Mindstorms Ultrasonic Sensor. Object moves away, the robot moves with the object. The program is very useful if you are doing STEM classes and you want to demonstrate results. People react very well to a robot following you like a dog for example.

Very simple and basic introduction to the color sensor in the LEGO Mindstorms EV3 set. The first program is to stop at a line. Then we can move from stoping at line to counting lines and even more complex tasks.
Counting lines and stopping on the third is the subject of this video. It is important to know how to do this in order to conduct more than one experiment in STEM classes (if we consider that each line is an experiment)
Use the color sensor to count the lines and stop on the third line. We do not use the wait block for this.
