Procedure 2.8 – Mount the Thrusters Onto the Vehicle Frame
Tools:
#2 Phillips Screwdriver
Pliers
Materials:
3 Assembled Thrusters
Assembled Frame
Electrical Tape
Figure 2.8-1: Thrusters Mounted on ROV Frame
NOTES: The thruster housings should be positioned within the thruster mounts such that
the back end of each motor (estimate where it is inside the thruster
if you can’t see it) is
placed right under the thruster mount. The mounts should not be clamped over the very
back of the thruster housings, where there is only wax, nor over the center of the motors,
where they might squeeze the motor casings. Placing them over the back end of the motors
will best resist the pressure of the tightened thruster mounts.
The tightness of the thrusters in their mounts depends upon the size of the thruster
housings as well as how far apart the mounting holes were drilled. If, after tightening a
thruster into its mount, it is still too loose, remove it and put a few wraps of electrical
tape around the thruster housing, just at the point where it will be clamped under the
mount, and then reinstall the thruster. For standard 35mm film canisters, about 8 wraps
of electrical tape will usually be the right amount for a snug fit.
Construction Steps:
1. Loosen, or remove, the thruster mounts using a #2 Phillips screwdriver.
2. Place the thrusters in the mounts according to Table 2.8-1. Mount the vertical
thruster with its propeller pointing upward, and orient the rear thrusters so that
the propellers are not pointed so far outward that they become the outermost
part of the vehicle (they could be damaged by contact with other objects).
