Interactive designer Alexia Léchot has built a delta robot with a ‘personality’ that interacts with humans through iPads. Deltu uses three moving arms, a couple Unity3d applications, and Arduino to play simple mimicking games.
According to Creative Applications:
The system uses two Unity3d applications where the application of the human sends HTTP request to the computer. There is also a Python server that sends the string through the serial to the Arduino which controls the robot.
The other player must precisely copy Deltu’s movements because it “is very demanding.” If not, it might change its mind and will shake its arms in a side-to-side motion that appears to simulate frustration. From there, Deltu leaves the game and opens the camera app instead, snapping selfies and posting them to Instagram.
