Who would refuse open source of the robot barman on Raspberry Pi with management via the smartphone or the tablet? So far, 385 people have donated $ 162,470 to Bartendro's Kickstarter campaign. The project aimed to receive $ 135,000, so you can say it has already taken place.

So what can Bartendro do? The authors describe it as “the most accurate robot for mixing cocktails,” the founder says that he “can make equally tasty drinks over and over again quickly and without errors.” Plus it's portable, so you can take it with you to parties - the build takes 5 minutes.

The small server on the Raspberry Pi is the center of the system, it manages up to 15 “dispensers” (this is the name of the pump with the Arduino-based control electronics connected to the server) connected to the right bottles that mix the right cocktails. Orders are entered via WiFi using a smartphone or tablet. From there, the robot is administered — recipes are introduced, calibration is performed, and ingredients are managed. There are reports about how many cocktails are made and how many drinks are consumed.
All code is open on
Github .
The creator of Bartendro believes that the robot in the future can be linked to Microsoft Kinect for accepting orders, a credit card reader for instant payment, social networks, or a drink prediction system that you might like. In general, he therefore made it Open Source - so that people would develop the capabilities of Bartendro.
