The design calls for the assembly of two micro controller systems,
the production of a water proofed box, the attachment of six motors, and the
assembly of a tether. You must produce the water proofed box and cut two
different sized thermostat wires. The construction of the design requires
a previous knowledge of the use of a drill and a soldering iron.

Most of the components connect to each other via a plug and the
plug’s proper port. Therefore, you do not need many tools to complete the
construction process. You must use a soldering iron to solder the thermostat
wires to the Adafruit Motor Shield DC output. In addition, you must use a drill
to create two holes in the water proofed apparatus. You use the scissors,
ruler, and the pencil to measure, mark, and cut three different parts during
the materials processing stage.

The design requires the
production of two parts. You must drill two holes in the water proofed box so
that the tether can enter and exit the water proofed box with ease. All of the
other components of the design fall under assembly, as one can purchase all of
the components pre-assembled. The Pelican Micro Case 1040 and the barb x male
compose the components required for the production of the water proofed box.
The other part you must modify is the thermostat wires. You must cut the
thermostat wire so that the thermostat wire is the correct length between the
motors and the motor shield as well as the length between the surface car
battery to onboard Arduino Uno.

The design requires the assembly of most of the parts, rather than
the production, because you purchase many of the components pre-assembled. The
DualShock Shield stacked on top of the Ethernet Shield stacked on top of the
Arduino Uno composes the micro controller setup on land. The DualShock shield
provides the female mate of a Playstation 2 Controller so that the male mate of
the Playstation controller can connect right into the shield. The Ethernet
Shield connects the land microcontroller to the onboard microcontroller. The
Adafruit Motor Shield stacked on top of the Ethernet Shield stacked on top of
the Arduino Uno composes the micro controller setup onboard the ROV.Eight
thermostat wires run from the output pins of the Adafruit Motor Shield to the
motors to power four DC motors and two servo motors. The onboard micro
controller setup rests in a waterproof box along with the external power supply
that connects to the GND and VIN terminal of the Arduino Uno to power the
motors. A waterproof camera attaches to the top of the hull of the ROV and runs
to the surface attached to the tether to live feed the video feed through the
laptop monitor with an ethernet cable.
