I’m a software dev, and I recently came across videos of this coffee robot (https://www.wsj.com/articles/robot-baristas-serve-up-the-future-of-coffee-at-cafe-x-1485781201). I’m really interested in building a small scale hobby project inspired by the coffee robot, but I’m not even sure what to search for. Can anyone suggest some resources or even tell me what search strings to Google? (“Mechatronics”? “Automation engineering”? “Robot arm control”?) I’m fascinated but at a loss.
