  3. Outline • Project overview • Project-specific success criteria • Block diagram • Component selection rationale • Packaging design • Schematic and theory of operation • PCB layout • Software design/development status • Project completion timeline • Questions / discussion

  4. Project Overview • 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.

  5. Project-Specific Success Criteria • 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.
