Scottish Natural Heritage seeks to identify animals and plants as part of a rolling program of 34 marine sites. In choosing the Falcon ROV from Seaeye, they specified a need for quality video imaging and picked a 3CCD broadcast quality camera with video multiplexed and transmitted over fiber-optics in the umbilical.
For their second camera, they required image scaling down to one millimeter, and so chose a Tritech laser image-scaling color zoom camera. Also important for SNH was the Falcon’s maneuverability, which gives access to sites with depths of over 115m.
For marine science work the Falcon is designed to perform tasks using sophisticated technology at a low cost. This is made possible by a range of task-specific modules that can be bolted on to the standard-build Falcon ROV and changed in minutes. The standard Falcon can be modified with options including a second camera, sonar, acoustic tracking systems and single function manipulator. The different mission-specific modules are incorporated within a polypropylene open frame that attaches to the core Falcon vehicle.
The distributed intelligence control system incorporates a single RS485 network and portable surface control units and has adapted the USB port concept to sense whichever system is fitted to the ROV, eliminating the need for interface cards on the remote vehicle, making fault diagnostics easier and, by removing the need for an electronics pod in the vehicle, making the ROV lighter.
