SNOOPY 



SNOOPY is the smallest in a series of lightweight, portable, unmanned, undersea 

 vehicle systems. Built as an experimental vehicle, it is capable of carrying a television camera 

 with a 100-watt, mercury vapor light source into the sea environment. As such, it can replace 

 a diver for many tasks in which observation or surveillance is required. SNOOPY (figure 5) 

 has two unique features: 



( 1 ) all propulsion power is sent from the surface by hydraulic lines and 



(2) an automatic depth-keeping capability is provided by a variable buoyancy 

 chamber and a depth feedback system. 



A small, electrically-powered grabber is mounted on the forward end for implanting or 

 retrieving lightweight objects. The vehicle is approximately 1 by 2 by 3 feet long (0.3 by 

 0.6 by 0.9 meters), weighs 50 pounds (23 kilograms) in air, and operates at speeds to 2 

 knots (1 meter per second) to depths of 100 feet (30 meters).
