Many countries of the world including Japan will become a full-fledged aged society. According to report in Japan, the elderly population aged 65 years or over in Japan will number 33 million and will account for more than 25 percent of the population. We have to support the elderly for independence in old age so that a variety of lifestyles is possible. With the development of the robot technologies, robotics researchers have developed various kinds of human assist robot such as walking aid system and manipulation aid system for supporting the elderly.

This thesis presents the preliminary work in the development of a biomimetic actuation mechanism for prosthetic and wearable robotic hand applications. This work investigates the use of novel artificial muscle technology, namely, shape memory alloys. The mechanism developed is based on the combination of compliant tendon cables and one-way shape memory alloy wires that form a set of agonist–antagonist artificial muscle pairs for the required flexion/extension or abduction/adduction of the finger joints. For the purpose of this thesis, an anthropomorphic four degree of freedom artificial testbed was developed with the same kinematic properties as the human finger. Hence, the size, appearance and kinematic architec-ture of the index finger were efficiently and practically mimicked. The biomimetic actuation scheme was implemented on the anthropomorphic artificial finger and tested, in an ad-hoc fashion, with a simple microcontroller-based pulse width modulated proportional derivation (PWD-PD) feedback controller. The tests were done to experimentally validate the performance of the actuation mechanism as emulating the natural finger’s joints movement. This thesis details the work done for the finger design process as well as the mechanisms and material used to achieve the actuation and control objectives. The results of the experiments done with the actuation platform are also presented.

a haptic interface is made of
— a mechanical position tracker
— actuated joints
it is just a robot attached to a human. Locomotion interfaces refers to interfaces involving the human body /legs/feet and to natural or induced locomotion.

Few of us are aware of the complex interactions between neural, mechanical, and sensory systems required to perform a task as simple as picking up a ball. To create a prosthetic arm capable of natural movement, it is necessary to mimic these sophisticated systems, as well as the intricate interactions between them, using cutting-edge actuators, sensors, microprocessors, and embedded control software. That was the challenge we faced when we embarked on the Defense Advanced Research Projects Agency (DARPA) Revolutionizing Prosthetics program.
