    12/32

    About12 to 53 new spinal injuries permillion population in the developedcountries every year1.

    Current estimates: 250,000 - 400,000individuals living with Spinal Cord Injury.

    So there is marketforHM

    Technical problems:

    o Learning the technology many unexpected thingshappened

    o accelerometer burn

    o ATMEGA8 (C) easily burn migrate toATTINY2313

    o LM298 motor driver burn develop own high currentmotor driver (60Amp)

    o Unreliable RF module migrate to Zigbee module

    Help Quadriplegia & Paraplegia to bemobile with the used of HM wheelchair.

    Testing results show that this system can be

    used with little training (~5min).

    The system had been design with safetyconsideration so that it will make the user

    feel confident to used it.
