Global Emergency Response System

Completed: May 2021 for Honors Introduction to Innovation and Physical Science of Engineering Class

 

Why?

  • Natural disasters kill nearly 60,000 people across the world each year

  • The communication barrier between cultures must be improved, especially in times of disaster

​

Objective

  • Build and code an emergency response vessel that can survive rough terrain, deliver life-saving supplies, and perform successful cross-cultural communication

Functional Block Diagram
Code Logic
  • A flowchart displaying how obstacles (infrared rays and magnets for the purpose of this class) are detected and avoided is shown below
  • Other coding consideration was given for turning and encountering an open path
Chassis Design​
  • The drivetrain consists of two large, motorized wheels in front and a skid apparatus in the back
  • After lots of testing, this design ultimately allowed for the smoothest turns in the shortest amount of time
  • A small motor is attached to the flag at the top, which spins to signal cargo delivery
  • The ultrasonic sensor on the front and side, as well as the IMU and IR sensors help with navigation and detection of hazards
    The chassis dimensions are as follows: 28x14x25cm. The cargo container is 50x50x55mm.
Cultural and Ethical Considerations
  • The cargo contained is able to display several images to represent the type of supplies it contains, as shown below
  • The images went through several design iterations after surveys were conducted, evaluating clarity and ensuring proper messages were conveyed
