2. Wheels: Go Forward Speakers: Say “Hello” OSCAR: Go Forward Say “Hello” Remote Control PC

3. Speaking to OSCAR OSCAR matches our voice to pre-recorded audio samples Must go forward!

4. Artificial Intelligence OSCAR: Open the door How do I open a door?

5. OSCAR: Open the door Steps to Open the door: 1. Find the door 2. Go to the door 3. Find and grab the handle 4. Twist and pull or push Artificial Intelligence

6. Power and Drivetrain System Wheel motors are powered by battery Wheel motors drive a belt to rotate the wheels Need two tachometers to figure out the speed of each wheel Computer and speakers are connected to power strip Standard Car Battery DC to AC inverter supplies power to the power strip Wheel Tachs

7. Computer System OSCAR has a regular home PC onboard OSCAR’s ‘brain’ Runs software to control the robot Commands: Forward, Backward, Left, Right, Say Commands are issued to OSCAR through wireless Internet

8. Robot Control Software Designed to be easy to use 4 different functions: Movement Speech output Sensor feedback Script recording/playback Microphone listens for speech commands All commands are sent to the computer on the robot wirelessly

9. SONAR System OSCAR uses SONAR (SOund NAvigation And Ranging) Outgoing sound wave Incoming sound wave How does OSCAR see his surroundings?

10. An Arm for OSCAR Designed to be retractable so it will fit in the top layer Currently, the team is gathering materials to build this Once built, circuits need to be built to control the motors Then, software can be written to control the arm

11. Goals for this year Build the retractable arm and design a way to control it with the computer Improve the speech recognition software Improve SONAR software in order to navigate OSCAR down the hall Install the Wheel Tachometers

12. Now for a closer look at OSCAR
