Braille E-Book Reader



  Blind person has access to literature through Braille script (alphabet is represented by combination of six pierced dots). This device uses a novel method of two tactile refreshable Braille cells consisting of six solenoid pins each for conversion of alphanumeric character into Braille character. Text is printed with each word alternately printed on either cell with user-suited speed. The user reads the words by placing both hands, one on each of the two cells and controls the device by three switches; one pair for scrolling books and a pause/resume switch.

Smart Electric Wheel Chair

  We built a model of electric wheelchair for a quadriplegic patient, who could control this chair using head or eye motion. We incorporated a GSM based emergency notification system on the chair so that it could notify the caretaker in case of acute emergency. It was also equipped with portable pulse oximeter, which constantly monitors patients blood oxygen level. When set to automatic navigation mode, the chair can mobilize to preset positions using RF based system.

AUTONOMOUS LASER TURRET


   This project was a miniature prototype demonstrating the functions of its original utilitarian form. It tracked the 2 dimensional motion of sample object in vision of camera using a mounted laser pointer. Dual axis motion was achieved by assembly of two metal gear servo motors. Atmega 16 MCU was used for servo controlling application. Image processing was procured with Laptop and 10 Megapixel webcam. VC++  with external Intel's OpenCV library served as the software platform.
