2013 - Modulus Robots 

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. Fitting the robot with a support attachment and plotter-device, the robot can utilize a humidity probe to detect water leaks. At the first sign of danger, it can inform a computer or trigger a built-in siren.

All four sides of the Service & Security robot variant with the center dome.

This Service & Security robot variant stands at approximately 33,5 centimeters or 13 inches tall.
A dark transparent dome is placed in the center of the Techno-Cake on the standard Service & Security robot version. This dome resembles a security camera housing, so the original plan for it may have been to add a security camera underneath it.
