Design and development of controlled arm using electromyographic signals

Prosthetics came into existence to simulate the physicality and functioning of missing limbs. Physical impairment can limit the physical function or fine/gross motor ability of limbs of an individual. In the cases of individuals with physical impairment, overall quality of life is severely affected. Technology could play a crucial role in enabling the physical functions of such individuals by developing prosthetics that are economical and seamless in appearance and usage. The present work aims to demonstrate the feasibility of designing a prototype of a controlled arm as a first step towards the development of low-cost prosthesis as a possible aid for low income people with disabilities. The prototype is controlled through a sensor that collects electromyographic (EMG) signals generated by flexing muscles in the user’s body. The design is realised using 3D printing technology.
