F12: Evil Watchdog
From Embedded Systems Learning Academy
Contents
Abstract
The Evil Watchdog takes the responsibilities of a pet guarding a house. It will roam around a predefined environment, avoid obstacles, and sound an alarm whenever foreign motion is detected.
Introduction
The objective of this project is to design a vehicle to imitate a guard dog. The following items will be incorporated to accomplish this goal :
- Motor driven chassis
- Vehicle will move in a random path detecting motion
- Vehicle will sound an alarm when motion is detected
Technology used
- Motion sensor
- Distance sensor
Team Members and Roles & Responsibilities
- Waymond Chen: Front motor control and distance sensor programming
- Hung Vuong: Distance and motion sensor programming
- Erik Montoya: Backside motor control and programming
