Development of a compact untethered remotely operated vehicle

Recently, the scientific investigations of marine environment, marine products and algae fields often require the use of underwater vehicle to perform survey and monitoring tasks. This paper describes a compact unthethered remotely operated vehicle (UROV). The vehicle is compact and light in weight by employing a VARIVEC propeller. The UROV operator controls by the UROV monitor including the data of GPS, electronic compass, sonar, depth and range sensor. The sensor data are extracted smartly by the Programmable System on Chip (PSoC) microprocessor. The performance of UROV is examined about the operating characteristics, image transmission, and remotely monitoring system. The temperature, conductivity, and turbidity of the sea surface are collected with accuracy.
