The [[Domestic robot|household robot]] '''Modulus''', described by the manufacturer as "the friend of homo''Homo sapiens''", was made by Sirius, a company Massimo Giuliana set up in 1982 for marketing home and [[personal computer]]s, and which decided to start building its own domestic robot back in 1984. When the first "Modulus" prototype had been realized, the company asked Isao Hosoe, a Japanese designer who has been living and working in [[Milan]] for many years, to study its "body-work". Hosoe's work, however, went well beyond this, and was followed by a complete technological reprocessing of the robot. Data Process was responsible for the design and manufacture of the electronic and mechanical parts, while Sirius used the expertise of an American company, the RB Robot Corporation, for the software (its founder, Joseph H. Bosworth, is known by some as "the father of personal robotics").
