Rationale behind our animal design
: We were inspired by frogs to create this design. It is green in colour and “shaped” like a frog thus it cannot be seen easily. This reduces the chances of people stealing our product as normally people don’t go around touching frogs as they might be poisonous.
: We were inspired by stingrays to create this design. As normally
stingray is deadly, people and animals will avoid it. This reduces the chance
of it getting eaten by marine creatures and people who have bad intentions.
: We were inspired by ducks to create this
design. As we do not want to disturbed a marine life or animal that might be
living in the pond or river when we are doing our research. By disguising our
product as a harmless duck, other animals will not feel so threaten by it.

Details on
what our product does:
First of all, it will move about the water. The user will manually set a specific timing at which
area to take the temperature. The boat will have send back the temperature which it
has taken and the coordinates of the location to the computer. The computer will then take the coordinates and mark
it on a map. For easier references later on. The user should repeat the process for one month to
get an accurate reading at the end.
Details on
how the electrical part work together to take readings:
The controller’s XBEE will transmit a
signal to the boat’s XBEE to give it command. Since the controller’s XBEE is
connected to the joystick module, the user will only need to use the joystick
to move the boat around. The boat will then base on the user’s
control move to a specific location to take the water temperature. The user will have to press a button
to active the temperature sensor to start taking the reading. The GPS will also be activated at the
same time to read its location. The readings will be sent via the boat’s
XBEE to the computer’s XBEE.
Details on
how the electrical part work together to move the boat around:
The motor is connected to a motor
shielding + XBEE which allows the user to control the speed of the motor via the
controller. The servo motor is also connected to
the motor shielding + XBEE thus the user can control the moving of the servo
motor. The servo motor will determine the
direction of the motor. Therefore, the boat can move forward in any direction.
