How does technology like robots receive a signal from a particular location, signalling for the robot to move towards the said location?

For an example, if a robot vacuum were to receive a signal from a particular location of a house to move towards that location, how is the signal sent? How does it work?

Im not sure what you ask for. Are you asknig how radio communication and antennas work?

Do you want to know how locating a signal works? Dust is not sending signals to a vacuum robot where it is, most of these robots ether drive in random directions or have a digital map of your house and go in every corner, there is no locating anythung except the carging base and that can be just backtracking its way.
