Android Based Graphical User Interface for Control

Project Overview

• Arduino microcontroller based vehicle– Variable speed motor forward/reverse using H-

bridge– Servo to control direction left/right

• Bluetooth module to send/receive data• Android application for control– User-friendly interface (twist to turn/touch to go)

• CMUCam integration

Complete System

All hardware components are available

Design Decisions• Microcontroller– Start with Arduino Duemilanove

based on cost and ease of use– Upgrade to Arduino Mega for

additional serial line• Bluetooth module– BlueSMiRF Gold module

• Wireless camera– Research wide range of ideas

Android ApplicationTilt device to turn
