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 siren. An arm with ample freedom of movement and considerable gripping power enables it to retrieve and carry items.
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.
This Modulus robot was originally the SV 601 version that was later equipped with an arm that was sold to me loose along with other parts and accessories. The missing shoulder motor cover was scratch-built out of plastic panels from an old TV and painted gray, although most photographs of the original cover depicts it in black plastic. I hope to one day replace the scratch-built cover with a fully original one.
