Abstract

The paper describes the investigations carried out for the communication of analogue video with digital data signals over a free space optical laser link for the remote control of a mobile robot. A number of digital data with analogue video modulation schemes are investigated. The aim is to make effective use of the bandwidth whilst maintaining an adequate duplex data link and a simplex video link. The rate of data transmission required to implement the control loop and the error rate are measured. Picture and data quality tests are described with degradation of the signal. A communication protocol is recommended for the particular application.
