Security robots are getting smarter all the time. Many of them can operate autonomously and even operate elevators. Take the Ugo robot for instance: it comes with two arms to operate elevators, open/close doors, and perform other tasks.
The Ugo TS series robot comes with autonomous control. It has a bird’s eye view camera installed. Its height can be adjusted from 104cm to 165cm. It has Mecnaum wheels to move in all directions.
