  Optical Wireless Communication (OWC) is regarded as an auspicious
communication approach that can outperform the existing wireless technology. It
utilizes LED lights, whose subtle variation in radiant intensity generate a
binary data stream. This is perceived by a photodiode, that converts it to
electric signals for further interpretation. This article aims at exploring the
use of this emerging technology in order to control wirelessly industrial
robots, overcoming the need for wires, especially in environments where radio
waves are not working due to environmental factors or not allowed for safety
reasons. We performed experiments to ensure the suitability and efficiency of
OWC based technology for the aforementioned scope and "in vitro" tests in
various Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) configurations to
observe the system throughput and reliability. The technology performance in
the "clear LoS" and in the presence of a transparent barrier, were also
analyzed.
