    Existing designs (The Seapearch ROV)

    There are many existing ROV designs that the Rainbow ROV will be based upon. One example is the 'SEAPERCH' from the book 'Build your own Underwater robot and other wet projects,' by Harry Bohm and Vickie Jensen. The Seaperch uses a remote control to control the ROV, and lets it move forward, backwards, left right, and to both slow and quick turns. The ROV design also has two thrusters that works in depths of up to three metres. The thrusters have the following materials:

    • A film canister
    • A Motor
    • A soldering iron with solder
    • A red pen and a silver pen
    • A Battery
    • Wires
    • uninsulated wires
    • Black electrical tape
    • Glue
    • Petroleum Jelly
    • Styrofoam
    • A Drill
    • Melted wax
    • An Electric frying pan
    • Old newspapers
    • Hot glue guns
    • A Propeller
    • Oven mitts
    • Drill

    However, the frame design of the ROV is different and needs the following materials:
    • Sandpaper
    • Pipe in the lengths:
      • 1 x 150 cm length of 12 mm
      • 2 x 114mm
      • 2 x 100mm
      • 4 x 76mm
      • 4 x 63mm
      • 6 x 38mm
    • glue
    • Two small floats
    • Dishwashing gloves
    • Instant bond glue
    • Drill
    • Clamp
    • Wire screening that is 25 cm x 16 cm long

    The Control box is the final main component of the ROV, and it has the following components:
    • A pencil
    • A ruler
    • A plastic box to sue for the control box
    • A 5/16" drill bit
    • A 1/8" drill bit
    • A 5/32" drill bit
    • A vertical switch <.li>
    • A starboard switch
    • A port switch
    • A battery or power supply
    • Thruster cable holders that lead to the previously made thrusters
    • A Locator washer
    • Stripped wires
    • Copper wires
    • Silver wires
    • A soldering iron
    • Soldering wire
    • some #31 wire nuts
    • a hook-up wire

    To connect all three main parts together there are a few more materials as listed below:
    • Three pipe clamps
    • A pencil
    • A 3/32" drill bit
    • screws and washers
    • Zip ties
    • Hot glue and hot glue guns
    • A protractor
    • Tape
    • weights such as bolts, nuts, lead or fishing weights

    The Seaperch ROV is a successful ROV design that we hope to base the design of our Rainbow ROV's on.
