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.

Would you like to resolve all the problems with the light/color sensors that you have? And to make all of them work in a predictable, stable way even when using more than one MINDSTORMS colour sensors. 

When using Color sensors it is important to calibrate them depending on the light conditions in your venue. In this way, the calibrated sensor will show values between 0 and 100 independent of the light conditions. But using the default EV3 colour calibration available in the colour sensor block could lead to unpredicted problems that are difficult to track and resolved especially when used with multiple Color sensors. So in this series of tutorial we implement the calibration ourselves discussing the principles of colour sensor calibration.

A common question is how to display arrays on the LEGO Mindstorms EV3 brick screen. Displaying values from an array is not different from any other display operation. In this tutorial, we would look at displaying two specific values. The minimum and the maximum for a specific sensor from the Advance Calibration Course Section

Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.

In this short animation we demonstrate how the LEGO Mindstorms Robot Inventor Distance sensors could be attached to the robot and then use to stop at distance from a wall. This wall could be the border of the field or another mission model. We need an attachment, we need a sensor and we need the robot. In the live video in the lesson we enter into more details and explanations of how the sensor is used. Programs for the distance sensor are provided in the lesson and in the LEGO Mindstorms Robot Inventor Programming course we enter into more details about how to program the distance sensor

In this video tutorial we demonstrate the classic algorithm for following a line with robots. It is widely used in FIRST LEGO League competition and could be applied to LEGO Education SPIKE Prime and to other robots also. The algorithm follows a line by moving to the left and to the right and trying to stay at the edge of a black line.
