1. AN HO IMDL SPRING 2014 D-Rex The Friendly Robot

2. Inspiration Robot Pet Act more like a real pet  Can be train  Respond to command How to do it?  Voice command  Vision

3. The System Raspberry Pi Pocketsphinx Soundcard Microphone OpenCV Camera Microcontroller ServosMotors

4. Pocketsphinx Record Write to.wav Read.wavProcessing What word is it? Send command to micro- controller Run on a loop Execute a command and then return to listening Check against a small custom dictionary  Speed up processing time

5. Microphone Change

6. Speech Recognition Status Program run fine most of the time under ideal condition Under noisier environment, the program register incorrect Added a cue for when it is recording  The RPi says “Ready” Plan on adding a keyword before command  Ex: “Dexter Find Green Ball”

7. Vision with OpenCV Objective: Complete various tasks based on speech command:  Roam around randomly, say hello when stopped in track  Look for a specified colored target  Tracking target

8. OpenCV Status Low frame rate  Decent enough for locating a fixed location target Change in lightning require recalibration  Will run a manual calibration program to get correct value  Not automated Sending the x/y location to the microcontroller is not working  Minor UART software problem
