1. DESCRIPTION
At the bottom of the vehicle, there are plastic feet
that can be replaced with the protective plastic frame.
Two DC motors inserted in the aluminium cylinders 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 (with a definite effort) by a user for cleaning.
The vehicle is connected with the surface unit via the thin cable transmitting power voltage, operation
instructions, data, and video signal from and to the vehicle.
The cable with diameter about 3mm is strengthened by the Kevlar threads (breaking effort is 90kg), and the
additional polyethylene 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 put on the top of the vehicle. The similar
floats may be put on the cable to give it neutral or a little positive buoyancy. The maximal operating depth of
the vehicle is up to 150m.
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.
By pressing one of the buttons on the joystick, the operator can enter the menu to tune up some of the
functions – calibrating the depth sensor and the compass, as well as some other functions.
