Deltu is a delta robot with a strong personality that interacts with humans through two iPads. Depending on his mood, it plays with you but if you make too much mistakes, Deltu might just get upset and decide to ignore you. Frustrated, Deltu will leave the game and take some selfies to post on Instagram.

"Robot with a mind of its own blasts tunes, takes selfies and destroys you at iPad games"

"Robots have learned to outsmart humans in a number of common games – and now, if your skills aren’t up to par, they just might get ‘upset’ with you"

Software & Hardware

There are two Unity applications. The one on the human's iPad sends a HTTP request to the computer. Then, there is a Python server that sends the string through the serial of the Arduino Uno.
