ABSTRACT

The RUN-D.B.C project, involves the design and construction of an autonomously navigating RC car. Development of the R.C car's subsystem modules will be divided amongst and performed by seven team members. Each team member will lead or significantly contribute to the development of at least one subsystem.

INTRODUCTION & OBJECTIVES

RC CAR OBJECTIVES
Successfully detect and avoid obstacles Autonomously navigate to a fixed destination, from a fixed starting location; based on feedback from a GPS Integrate communication between the RC car's master controller and an Android device, using Bluetooth Integrate system hardware communication using a PCB

TEAM OBJECTIVES
Strive to learn as much as possible, in order to develop a professional product Establish and enforce professional software design standards Establish and enforce professional hardware design standards Achieve 100% code coverage, during unit testing Carefully document and track all bugs encountered and patched, during development Clearly communicate the development of all modules of the RC car

CORE MODULES OF RC CAR
