  • Reusable code, Someone could go buy glove + bluetooth module and create their own product that could be controlled.
  • Controllable car that can be driven wirelessly w/o vision from driver DON’T TALK ABOUT REAL WORLD APPLICATIONS
  • Sensors>controller capable of decrypting hand motions to readable outputs>sent via bluetooth to what is controlled (this case our vehicle)> microcontroller takes bluetooth inputs and encrypts the glove outputs to PWMs for both motor and camera---Camera > sends video feed
  • Glove: Basic layout (sensor locations); full arm glove;
  • Primary inputs: Sensors Primary processing: MSP430 Output: Readable bluetooth commands
  • MMA7260; wrist cancelation; x-y-z rotation planer movement
  • Use to generate a variable voltage that can be read by the MCU on the glove
  • Work similar to flex sensor; variable resistor that can be read as a variable voltage
  • Heart of the glove; Again, MSP430 decodes movement into packets to be sent out via bluetooth, has an RS232 to connect to computer
  • Linksys camera MP-101 Pan and Tilt motorized platform Bluetooth control inputs + and -15 degrees vertical tilt, + and -90 degrees horizontal sweep
  • Glove and car worked on simultaneously, once vehicle constructed work on camera and start work on bluetooth, testing throughout
  • Chris and blake primarily on glove, me and brian primarily on vehicle and peripherals. Everyone working on camera, testing and debugging

    • 9. Accelerometers
      • MMA7260Q Triple Axis Accelerometers located on the base of the wrist and the top of the hand.
      • By comparing accelerometer outputs from each, we will be able to effectively deal with ambient movement by the person controlling
    • 10. Flex Sensors
      • 4.5 inch Flex Sensors for each digit of the glove.
      • Act as variable resistors with
        • Straight (unflexed) resistance: ~9000 Ohm
        • 90 degree bend resistance: ~14000 Ohm
        • 180 degree bend resistance : ~22000 Ohm
    • 11. Force sensors
      • One located at the end of each digit on the glove
        • Allows for additional user inputs for further control
