Are you annoyed that touching door traps during COVID is a necessity? Build an adoorable and your problems are gone!
We are a small team of ETH Zurich students and we were challenged by the pd|z department to develop something to help fight the corona-virus. There were four weeks available in which we had to find an approach to contribute to the motto “Don’t get infected & don’t spread the virus”.
Our solution is an automatic door opener. It is designed in a way that minimizes the exposure to contaminated surfaces and is easy to build.
The result of the four weeks full of hard work was a finished prototype as well as a detailed construction manual. Because we all have to help each other out during this hard time we wanted to share our work with you.
In the following google-drive folder you will find the mentioned construction manual as well as the code and the files for the 3D-printer. Please keep in mind that the manual only describes a first prototype. We are not able to guarantee that you will receive a working product by following our manual. The included files are written in German, because the project took place in Switzerland.
This project implements a touch-free door opener using an ultrasonic sensor and a high-torque servo motor.
Proximity Detection Logic: The system uses an HC-SR04 ultrasonic sensor to detect a hand or object within a 5-10cm range. When triggered, the Arduino signals a servo to rotate, physically pulling a cable or lever to unlatch the door.
Power Efficiency: The firmware includes a timeout mechanism to return the servo to its original position after 5 seconds, ensuring the door can relatch properly.
Safety and Hygiene
Visual Feedback: An integrated LED ring changes from Blue to Green when the "Open" signal is received, providing intuitive feedback to the user without physical contact.
