Using optical communication for remote underwater robot operation

Abstract: Abstract-Underwater vehicles are typically operated using a tether or a slow acoustic link. We present an underwater optical communication system that enables a high-throughput and lowlatency link to an underwater robot. The optical link allows the robot to operate in cluttered environments without the need for a tether. We demonstrate the performance of the system in a number of experiments which characterize the optical link and demonstrate remote control of the robot using a human input device.

“…In addition, our high-bandwidth low-latency streaming solution plays a critical role in diverse underwater robotic applications, such as dexterous operations using Remotely Operated Vehicles (ROV ), real-time tele control in narrow caves and shipwreck settings, and off-board visual autonomous navigation setups. The presented video streaming solution further complements our previous work, which demonstrated wireless remote control of an underwa ter vehicle using free-space optical communication [13].…”

“…Transmissions at extremely low frequencies (ELF, 30-300 Hz) can propagate through conductive seawater, and are commonly used for communications by US Navy submarines [113], however transmission at these frequency bands requires large antennas and high power, making it impractical for use by small autonomous vehicles. Optical communications using lasers or LEDs have also been considered for high-bandwidth underwater communications [137] and can offer high throughput in certain conditions (several Mbits/sec at ranges up to 100-200 m [65,76,77,130]), however optical links are affected by high scattering due to particles in the water and have limited range. They are also challenged by ambient light in shallow water operations.…”

“…These channels have very limited bandwidth with throughput on the order of tens of bytes per second depending on range, packet size, other uses of the channel (for instance, navigation sensors), and latencies due to the speed of sound in water [4], [5]. While much higher data rates have been achieved using underwater optical modems for vehicle control [6] and two-way communication [7], these systems are limited to ranges on the order of 100 meters and are inadequate for long-range communication [8]. In the absence of missiontime operator feedback, an AUV must either navigate along a preprogrammed course or use the data it collects to alter its behavior.…”
