The cleaning robot operates as follows and has the following features:
Without human assistance or supervision, the cleaning robot opens the elevator door and gives the elevator directions about which floor to stop on by interfacing with it via the optical transmission devices installed in both the robot and the elevator. When the elevator arrives at the correct floor, the robot disembarks. The process is thus very similar to the way people ride elevators.
The laser range sensor has an improved signal processing program that allows the robot to detect obstacles and thus ensures greater safety.
The lifting mechanism of the dust suction component, which in the earlier model was powered by electricity, is now operated manually with wires, making it simpler and more reliable and leading to cost savings and a lighter body weight.
An optional feature is a small camera that can be attached to the robot to record its movements on hard disk, allowing users to observe how the robot was working and the surrounding environment.
