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 first Base unit can be added to for different functions. As it stands, it can be used in hobbies as a home computer, self propelled peripheral, and can be useful for people wanting to learn how to program robots. The simplest attachments that can be connected to the Base unit are a vacuum cleaner and a plotter-device that uses felt-tip pens to produce drawings of considerable precision.

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".
