THETIS: an underwater remotely operated vehicle for water pollution measurements

This paper describes the unmanned underwater remotely operated vehicle (UROV) THETIS, an easy to operate vehicle suitable for exploiting water environments. The subsystems composing our system, as compared to conventional ROVs, are discussed and evaluated. The vehicle’s primary use, at the present stage of development, is to perform underwater observations as well as temperature, pH/dissolved O2 and suspended sediment measurements for underwater pollution studies. Using simple components, the ROV’s high reliability and efficient performance offer a versatile and cost-effective work system. q 1998 Elsevier Science B.V.
