DESIGN OF AN ARDUINO-BASED PLATFORM INTERFACED BY BLUETOOTH LOW ENERGY WITH MYO ARMBAND FOR CONTROLLING AN UNDER-ACTUATED TRANSRADIAL PROSTHESIS

Abstract

In this project a brief overview on the latest advancements in upper-limb prosthetic technology is presented these mainly derive from the advantages offered by increasingly smart and high performance electronic devices and modules, which now a days are commercially available at low cost then the electronics of Adams hand, a transradial myo electric prosthesis for upper limb. Amputees, is describes. The devices is equipped with sensor and actuators that simplify at aid the movement; in particular, the mechanisms in which placed can actuated 15 degree of freedom with just one motor (instead of the five or six motors conventionally used in other commercial available prosthesis devices). Two servo motors are actuated the wrist movement. The myo electric signal use to control the prosthesis are detected through the myo armband, which integrates eight electromyography (EMG)electrodes and an inertial measurement unit (IMU) based on invensense MPU-9150 IC; all these data sent by myo armband through BLE protocol to the realized control electronics which actuates the used motors.
