Applications and Implications

Assignment

Propose a final project masterpiece.

What will it do?

  • Launch a Paper Airplane.
  • Change the pan & tilt of the launcher.
  • Remotely controlled via bluetooth remote control.

Who has done what beforehand?

What will you design?

  • Pan/Tilt mechanism.
  • A mechanism to launch the airplane.
  • PCB board(s) design
  • Enclosure for the launcher electronics.

What materials and components will be used?, Where will they come from? & How much will they cost?

What parts and systems will be made?

  • Pan/Tilt mechanism,Enclosure, Motor Holder.
  • Output Components:
    • Servo Motors → Moves to specific angles.
    • DC Motors → Accelerate to launch the airplane.
    • Solenoid → Push the airplane between the moving wheels to be launched.
  • Input Components:
    • Joystick → Changes the angles of the servo motors which changes the Pan/Tilt angles.
    • Push Button → Trigger the Solenoid to push the airplane.
    • Bluetooth → Communicate Between the launcher & the remote control.
  • Systems:
    • Setup a communication between 2 bluetooth (Master & Slave)
    • Transmit and receive multi-Value serial data in the same packet via bluetooth

What processes will be used?

  • Cardboard Prototyping.
  • 2D Design and Laser cutting.
  • 3D Design and 3D Printing
  • Electronics design and production.
  • Embedded programming.
  • Testing

What questions need to be answered?

  • How to design and fabricate the project, mixing two fabrication techniques or just one?
  • What MCU will you use?
  • How to setup Master & Slave bluetooth communication.
  • How to transmit and receive multi-Value serial data in the same packet via bluetooth.

How will it be evaluated?

  • The Project able to launch a paper airplane successfully.
  • The ability to control the launcher and change it's angles.
