Deltu by Alexia Léchot – iPad as a ‘mirror interface’ between humans and robots


Created by Alexia Léchot at ECAL, Deltu is a delta robot (wiki) with a personality that interacts with humans using two iPads. Created using arm technology normally found in 3d printers, Deltu uses three different applications on the iPad Alexia built for it, using symmetry as an interpretation, a mirror and a reflexion of our own image.

The first game is a drawing game named “Together”, where Deltu mimics and interprets what we draw. The second one is a battle between the machine and the human. And the final third one is a memory game where the human must learn from the robot. Alexia designed these three games are a reflexion of the special relationship we have with robots and the evolution of this relationship.

The relationship we have with robots/AI that have been created to enhance our performance, but have become a source of learning, is unique and exciting. The android’s place in society has not yet been defined and remains to be determined; for me it is the best source of inspiration.

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.
