IBM - CVUT Student Research Projects Robotic Head with Mimic Facial Movements Jan Kofroň

IBM - CVUT Student Research Projects 2 Guidelines Design and realize mechanic and electronic part of robotic head Design API for client computer application Create simple demonstrating application –Cooperate with Talking Head project

IBM - CVUT Student Research Projects 3 Features User head tracking using eyes Speech simulation using mouth Speech output through speaker using speech synthesizer Facial mimics simulation Touch sensitivity

IBM - CVUT Student Research Projects 4 Current version (mechanical part) Eye movements –Horizontal direction –Vertical direction Mouth opening Head horizontal rotation

IBM - CVUT Student Research Projects 5 Current version (electronic part) ATmega32 microcontroller (design board) –2 PWMs for driving servos –TIMER for servo multiplex (up to 8 servos) –TIMER for stepper motor moves Communication via RS232 with client app –Simple command protocol (see documentation)

IBM - CVUT Student Research Projects 6 Next version (mechanical part) Modeled face (funny fairy-tale creature) Moveable –mouth, eyelids, eyebrows, cheeks, funny ears Touch sensitivity

IBM - CVUT Student Research Projects 7 Next version (electronic part) AT90USB1287 (own PCB) –Up to 16 servos –Up to 4 stepper motors Communication via USB with client app –User space driver and DLL implementing API DAC, Amplifier and Speaker –Speech synthesis output

IBM - CVUT Student Research Projects 8 Conclusion Project brings me new experiences with –Connecting existing projects together –Schematic and PCB design –Tiny mechanics
