Welcome to the website about the Modulus robot line by the Italian company Sirius.
Modulus is a Commodore 64 driven personal robot available
in three separate versions. The self-propelled Base can follow a programmed itinerary, enabling it to function as a plotter and even do light vacuuming. Adding a second module to the Base gives you the Security & Service Robot, which can signal the computer or sound an alarm upon detecting the presence of gas, water, smoke, or an intruder, as well as report on the weather. With the third module in place, you have Moddy,
with two independently moving robot arms that enable him to retrieve and carry objects.
