At the end of the timer, the bag is raised clear of the cup to end the brewing. It’s a remarkably simple design that almost evokes chindogu (the Japanese art of useless inventions) if not for the fact that the robot actually serves a useful purpose.
The components for 3D printing the robot are available online, consisting of a case, a container for the Arduino-powered electronics, the … // Read more: original article.
