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
