With the use of ultrasound the LEGO Mindstorms EV3 & NXT Ultrasonic sensors could detect the distance to an object. You can use it in many different ways most of them very interesting and fun. Some of them a little more challenging, but rewarding.
This is a 10 out of 10 tutorial for pushing gently on a mission model. We also discuss how to build robots that tolerate error and auto-correct their behavior.
In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.
As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. One of the “eyes” on the sensor head is the transmitter and emits an ultrasonic wave and the other “eye” is the receiver which receives the wave reflected back from the target.
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.
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
In the first LEGO tutorial we started following a wall with the Ultrasonic Sensor. In this tutorial we would improve the program, remove the zig zag movement and make it very smooth.
Tasks for school STEM classes or home exersie. Try to solve them to submit your solutions below.
Arriving at a final solution. There is still room for improvement on using the Mindstorms Ultrasonic Sensor for aligning to walls, but we hope the whole five videos could give you a good idea of how to start with a problem and reach a solution.
If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.
We explore some common mistakes when a program is developed and becomes complex. We then try to remove part of this complexity.
There is no block for programming the Ultrasonic Sensor in the retail version of the LEGO Mindstorms EV3 software. In this video tutorial we will show you how you can download & import such blocks in order to use the sensor.
In this video tutorial we demonstrate a few ways to use the Distance sensor from the LEGO Mindstorms Robot Inventor on FIRST LEGO League competitions. We don't enter into the details about programming as we do in the LEGO Mindstorms Robot Inventor Programming course, because here we demonstrate the behavior of the robot when the sensor is use and we make the argument that you should always use sensors at FIRST LEGO League competitions
