There were hardly any changes made from the initial plan to the completed plan. Other than adjusting the measurements of the boat, we finalized the placement of the motor and determined how the fish are going to be made. We also looked towards using blue tac to secure the motor onto the boat, making it reusable compared to hot gluing it on. Considering the age of our intended audience, we designed this toy to be more kid-friendly, with no sharp edges or complicated switches.

The techniques we need knowledge on for this design will mainly be how to connect the double sided DC motor to the battery with wires since we have not worked with motors or batteries before.

The plan to create the design:

  1. Make the boat: Cut out the main pieces of the boat with styrofoam using the measurements listed above.
  2. Hot glue all pieces together to form the basic boat. Make sure there are no gaps and no water will leak in.
  3. Attach two wires to the double sided DC motor. Attach another two wires to the battery.
  4. Connect the two wires on the motor to the two wires on the battery and secure with electrical tape.
  5. Plug one metal skewer on each side of the double sided motor.
  6. Make holes on the sides of the boat and ensure the metal skewer is long enough and that there is enough space on both sides.
  7. Stick the plastic disks into the skewers.
  8. Cut 8 popsicle sticks in half and hot glue 8 on each bottle cap. Make sure they are spaced evenly and stable.
  9. Hot glue the bottle caps onto the plastic disks. Once dry, turn on the motor test the paddles.
  10. Secure the motor and battery onto the boat with blue tac.
  11. Make the fishing game: Cut a 10 cm wooden skewer and hot glue it onto the boat. Make sure that it is durable and stands upright.
  12. Hot glue one end of a 20cm piece of string with mini magnet balls. Hot glue the other end onto the wooden skewer.
  13.  Attach one mini magnet ball to each fish. Ensure the magnets are fully dried before testing.

We will know this design is successful when the boat is able to float and paddle on water. The boat will not sink because of the weight of the motor and battery and no water should leak in. Additionally, the magnets should be able to attract the magnets on the fish and not fall apart in the water.
