A set of small robots needs to be equipped with wireless devices. Consider the usefulness of the following devices if used in a laboratory environment:
(a) Infrared (IR)
(b) Diffused infrared
Obtain information about infrared communication from your favorite Web site.
Diffused Infrared (IR) is an indirect and non-line-of sight communication. The diffused infrared signal, which is emitted from the transmitter, fills an enclosed area and uses the room’s surfaces to bounce the optical signal between the transmitter and the receiver. The advantage of diffused IR links is that they provide robustness against shadowing and behave as RF (radio waves) within a room enclosure in comparison to basic infrared communication, which is a line of sight communication. Also using basic IR communication may result in disruption of communication in case robots are non-line-of-sight, which is not the case with diffused IR. The disadvantage of diffused IR is that it uses the signal in a complete enclosed area so we need to use different code to identify different communications.
