Abstract: With increasing demand in the need for fast and secured transmission of data from one place to another in a wireless medium, many innovations open up with respect to the use of communication protocols. Of late, spectrum availability appears to be a very scarce resource and invites alternate methods of transmission to fortify the emerging challenges. The paper investigates the properties of a visible light communication (VLC) medium and develops a scheme for controlling the position of a Li-Fi-based robotic vehicle. The fast transmission properties of light signal along with its edge over radio frequency and or Wi-Fi communication augur well to exploit the potentials of the Li-Fi environment. The methodology involves the use of an Arduino microcontroller for the generation and reception of control signal at both the transmitter and receiver ends, respectively. The response to varying widths of pulse position modulation (PPM) signals bring out the ability of the scheme to respond to changes in position at varying speeds. The results envisage a new dimension to the scope of robotic vehicles for a space in automated domains in terms of faster and precise operational ambits.
