    1. Senior Project Design Jason Niccoli, and Tim Tse

    3. Desired Features Recognize voice commands: - Dance: dance to a music pattern, 5 dancing patterns and change each time it hears a different music pattern - Turn around: turn 180 degrees - Turn left: turn counter-clockwise 90 degrees - Turn right: turn clockwise 90 degrees

    4. Forward: move straight Backward: move back Stop: go into standby mode and wait for any other command.

    5. Optional Features LED panel on the face to allow for blinking eyes. Audio acknowledgment of commands. “Understood” or “ok” Increased complexity of dance sequences. Area sensors to avoid running into things. Added audio commands.

    6. Materials Power: Battery Switch: On/Off Microcontroller: Mini-dragon Board + Development Board LED: Eyes, added features Servos: Arm rotation Microphone: Listens to commands Wheels: Move and turn Motors: Move wheels and arms Voice Recognition Software: Recognize commands

    7. Battery One 9.6V Volt 2000 mAH NiMH Battery Pack for Walking Robots $12.99

    8. Switch on/off This is a three-position center-off DPDT mini power switch. $1.5

    9. Mini-Dragon board EEPROM: 4KB SRAM: 12 KB FLASH: 256KB 16 MHz crystal, 8 MHz default bus speed and up to 25MHz bus speed Can support any C compilers and Debuggers Program in C, BASIC, Forth and Assembly language $ 99.99

    10. LED Very high quality IR LED. Lumex OED-EL-1L2. Sold in ten-packs. $2.5

    11. Servos Range = 360° Voltage = 4.8 - 6.0vdc Torque = 57 oz.-in. Weight = 1.66 oz. Speed = 60rpm $12.99 each

    12. Wheels Diameter = 3.5" Width = 1.75" Hubs = 6mm (HUB-05) Motor = Any 6mm output shaft (GHM-01 thru GHM-04) $19.50

    13. Motor Gear head motor Voltage = 12vdc RPM = 138 / 90:1 Outside Diameter = 27mm $ 17.00

    14. Voice Recognition Software Voice recognition software requires a language model and an acoustic model to actually recognize speech, possible source: Voxforge’s, English acoustic model. Open source voice recognition software: Sphinx – Linux environment/Java, HTK- ??, CAVS- Internet based/C++, Julius- Linux & Windows/C++.

    15. Cost 2 wheels : 19.50 x 1 = 19.50$ 2 motors : 17.00 x 2 = 34.00$ 8-10 servos/steppers: 12.99 x 10 = 129.90$ Set of 10 LED’s: 2.50 x 1 = 2.50$ Mini-Dragon Board: 99.99 x 1 = 99.99$ Switch: 1.50 x 1 = 1.50$ Battery: 12.99 x 1 = 12.99$ Sheet Metal (aluminum- 6061 1/8” thick 2’x2’): = 79.08$ Total = 379.46$
