Concierge has been designed to stay on the side of an office door, following people in the corridor with its sight, and, when people come close, let them in or deny entrance depending on a preset value. The head has been designed by Maximiliano Romero, designer from Phy.Co. Lab, and haired by Andrea Bonarini from AIRLab. Depending on hair, different characters are implemented by changing the quality of the movement.
