Outline

3

Our goal is to design a robot vehicle which can manually controlled by human with Android phone.

The vehicle can capture 360 degree images, sense the surroundings, feedback the information back to the phone, collecting data and images and some other minor functions.

Project Overview

4

PSSC #1 : An ability to control the motion and direction of the vehicle.

PSSC #2 : An ability to avoid obstacles using ultra-sonic sensors.

PSSC #3 : An ability to stream the video to an Android device.

PSSC #4 : An ability to monitor battery status and give low battery alert signal.

PSSC #5 : An ability to send and receive all data and video between the vehicle and Android device.

Android Device Preliminary interface finished Android programming tests Will work on communications with servers

Current Process ~ Before Spring break: Finalize schematic & PCB layout ( no error),

hardware testing and prototyping. After Spring break ~ the beginning or mid of

April: Software development in Android and

microcontroller and hardware development Mid of April ~ End of April: Debugging software, combine software with

hardware and finalize the project
