Welcome to the website about the Modulus robots by 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.
