Remote Control Speakers: Say “Hello” PC OSCAR: Go Forward Wheels: Say “Hello” Go Forward Speaking to OSCAR Must go forward! OSCAR matches our voice to pre-recorded audio samples Artificial Intelligence OSCAR: Open the door How do I open a door? Artificial Intelligence 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 Power and Drivetrain System DC to AC inverter supplies power to the power strip Standard Car Battery Wheel Tachs • 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 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 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 SONAR System How does OSCAR see his surroundings? Outgoing sound wave Incoming sound wave OSCAR uses SONAR (SOund NAvigation And Ranging) 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 Goals for this year Improve the speech recognition software Improve SONAR software in order to navigate OSCAR down the hall Install the Wheel Tachometers Build the retractable arm and design a way to control it with the computer Now for a closer look at OSCAR
