1. DESCRIPTION
Two DC motors inserted in the aluminium hulls serve as the thrusters . The rotation is transmitted to the
screw propeller using magnetic coupling disks. One disk is fastened to the motor shaft inside the body, and
the other one to the screw propeller shaft inside the cone-shaped head . The cone-shaped head is filled
up with water and may be removed by operator for cleaning (see manual).
The vehicle is connected with the surface unit via thin cable transmitting power voltage, operating instructions,
data, and video signal from and to the vehicle.
The cable with diameter 6mm is stregthened by the Kevlar threads (breaking effort is 90kg) and the additional
polyehylene shield. The maximum cable length is up to 250m. To counterbalance the weight of the vehicle
and give it neutral buoyancy, the foam polystyrene float is installed to the top of the vehicle. Similar floats can
be put on the cable to change the neutral buoyancy to a little positive. The maximal operating depth of the
vehicle is 200m.
Using the control pads and the joystick, the operator can move GNOM forward-backward, turn to the right –
left, up – down; adjust the thruster speed and the brightness of the lights. All the data are displayed on the
monitor in "TV-text" mode. By pressing one of the buttons on the joystick, the operator can enter the menu to
tune up some of the functions – calibrate the depth sensor and the compass, as well as some other functions.
The "Sony PS" controller is connected to the control and power module installed in a waterproof case,
with built-in 15" monitor. The power supply operates from 100 to 230 VAC or 12 VDC.
