PLUTO PALLA - Lightweight ROV for deep sea exploration
PLUTO PALLA is a small size ROV designed for deep scientific observations down to 2000 meters depths.
PLUTO PALLA is an “eyeball” shaped compact inspection ROV characterized by its compactness, lightweight and portability, making it deployable from any small craft of opportunity and suitable for scientific observation, ocean floor inspections and much more.
The unique compact characteristics allow the entire system to be transported in the trunk of any mid-size car, embarked aboard any kind of a vessel and immediately deployable without the need of fixed on board installation. PLUTO PALLA grants unprecedented underwater scientific research possibilities and exceptional visual inspection capabilities.
Easy launching of a small vehicle weighing only 60 kg.
Fast dive (1000 m in 15 minutes) using disposable ballast.
Inspection mode #1: vehicle hanging on the umbilical cable, yawing and moving horizontally by remote operated propulsion and adjusting depth by umbilical cable pay out or recovery.
Inspection mode #2: following ballast release the vehicle acquires full ROV maneuverability in the water volume, taking advantage of:
PLUTO PALLA includes 4 main items: the vehicle, the umbilical cable winch, the control console and the battery charger.
The main body is a carbon fibre sphere 45 cm diameter housing all electronics. The sphere can be tilted up and down + – 90°. A high definition video camera, a still camera, a LED (high intensity floodlight) illumination lamp, navigation sonars, are all tilting at the same time.
Two carbon fibre battery pods.
Two horizontal and two vertical high efficiency thrusters, pressure compensated.
Weight in air: 58 kg
