ABSTRACT
The technology developed so far has been retrofitted on a professionally made prosthetic device called AMAL. The system is characterized by its simplicity, robustness and reliability. The civilized society has enacted many laws against discrimination of the disabled, created special arrangements in official building constructions, in airports and other places and some facilities in mass transport systems. However, all the contributions that laid the foundation of research in prosthesis were made in the early or late 1970s when information technology and computer-related hardware were crude and expensive as compared to the present day. The technologies used are derived from the experiences gained from extensive research in the area of robotics, artificial intelligence and control. To make the system inexpensive, sensor-based feedback has been kept to a minimum. In a successful prosthesis, the fitting of the socket to the stump is a very important factor.
