How to align to a wall with Ultrasonic Sensors. Complete solution (part 5)
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.

EV3 basics course. Ultrasonic Sensor. Follow an object (part4)
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.

EV3 basics course. Ultrasonic Sensor. Detect object (part1)
We are introducing the LEGO Mindstorms EV3 Ultrasonic Sensor. The first program is actually to detect an object and stop near it, at about 4 inches/10 centimeters. The ultrasonic sensor could be used during robotics competitions, but most of its use is for experiments.

How to use the Ultrasonic Sensor with the Catapult built from EV3/NXT (Part 5)
This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.
