Modulus by Sirius.

1986, Italy.

Modulus is a robot designed for adaptation to the widest possible range of applications with its modular Techno-Cake system, robot parts and accessories. Modularity, hence its name, is one of its principal characteristics. Available in three configurations - Base, Service & Security, and Moddy. The second Modulus configuration, the Service & Security robot, is obtained by fitting the Techno-Cake home-security and service unit onto the Base. The components allow the robot to signal the presence of smoke, gas, and intruders. At the first sign of danger, it can inform a computer or trigger a built-in siren. Fitting the robot with a support attachment and plotter-device, the robot can utilize a humidity probe to detect water leaks.

Trivia.

Sirius became the European distributor of the RB5X robot by RB Robot Corporation in 1984 and was inspired to develop their own robot the same year.
The Modulus robots were designed by Isao Hosoe Design Studio who won the Compasso D’Oro award in 1986 for its design.

Personal note.

This Modulus robot was once part of a payment lot given by Sirius to Joe Bosworth for his services with developing the software for Modulus. It was later sold to my collection by Joe Bosworth who had read my various posts online about my search for the Modulus robots and how important they were to me. It is now a very special part of my collection after having been owned by "The father of personal robotics".
