The aim of this project is to induce empathy of the viewer towards "characters" which are nothing more than articulated metal structures. Each machine has a spherical body and eight arms made of aluminum tubing. It has a sensing system, a motor system and a control system that functions as an autonomous nervous system. Machines are suspended from the ceiling and their arms are actuated by pneumatic valves and cylinders. Ultrasound sensors allow the robots to detect the presence of viewers in the nearby environment.
