Handicap Arm with Embedded Electronics

The project uses a microcontroller as the processor to enable communication among sensors, processors, and motors while creating the Dynamic Arm as the world’s first microprocessor-controlled adaptive arm.

There are several health care products that utilizes embedded electronics to improve the quality of life. More advanced prosthetic limbs with microprocessors are being developed to provide comfort, stability, and balance to handicapped but active members of society.

The use of microprocessor gives the Dynamic Arm the ability to adapt to various weight loads and conditions and it works by reading nerve actions from the living arm and translating these signals into computerized movement. Things that are many times its weight can be lifted strong enough by the Dynamic Arm.

The first commercially available microcontroller-controlled artificial limb is the C-leg or Computerized leg. It continuously process information gathered from various sensors to complement the movement of the other leg, making it work like an instantaneous computer. This is made possible by controlling hydraulic and damping systems every step. For users to change modes during high-speed activities like cycling, skating, and others, a wireless remote control can be in place. It has standing mode for stabilization.
