According to the cortical homunculus, our hand function requires over one quarter of the brain power allocated for the whole body's motor/sensory activities. The evolutionary role of the human hand is more than just being the manipulation tool that allows us to physically interact with the world. Recent study shows that our hands can also affect the mirror neuron system that enables us to cognitively learn and imitate the actions of others. However the state-of-art technologies only allow us to make cosmetically true-to-life prosthetic hands with cadaver-like stiff joints made of mechanical substitutes. And very few research groups know how to design robotic hands that can closely mimic the salient biological features of the human hand. The goal of our project is to reduce cognitive and physical discrepancy, in the cases where we need a pair of our hands interacting with a different environment remotely. Our project will try to answer the following questions: With the great advance of 3D-printing technologies, and promising new materials for artificial muscles and ligaments, can we design a personalized anthropomorphic robotic hand that possesses all the favorable functions of our very own hand? With such a robotic hand, can we reduce the control space, and establish a easy mapping for the human user to effectively control it? Is it possible to teleoperate the robotic hand to perform amazingly dexterous tasks without force feedback as those surgical robots demonstrated? To answer these questions, we are going to investigate the design and control of our proposed anthropomorphic robotic hand.

The contents of this book is product of my research. This project was critically aimed for study of Stretch Sensor which can be used for finger movement detection in Anthropomorphic robot hand.Over the past decades, there have been many activities in the design, analysis, and control of artificial / robot multifingered hands to emulate the functions of the human hand.Hand movement has abundant powers of expression with complex finger joint motions. This can help to interact with robot arm or dexterous hand. Some glove-based devices have been employed to capture full degree-of-freedom (DOF) human hand motion. Unfortunately, such devices are expensive and cumbersome.Hence goal of many researches has been to design a glove-based sensor system that could easily be mounted onto the human hand to capture hand movements. Therefore, the dissertation is focusing on sensing joint movements of fingers and wrist of a human hand and contributes to easy sensing technique. The main contribution of this dissertation is advancement of robot hand dexterity through use of joint movement sensing of anthropomorphic robot hand along with existing theories of movement sensing.

This thesis deals with the control of an anthropomorphic arm-hand robot by focusing on two aspects: the control of the fingertip force and the coordination between the arm and the hand. The force control of a robotic finger remains difficult despite the advances in current state-of-art. This is due to the small size of the finger, its low communication bandwidth, the lack of precision of the position sensors and the significant backlash in the actuation systems. A new approach controlling the fingertip force by adjusting the joint torque saturation parameter shows better results. Not limited to pure force control, this control method is proved to also have good performance when applying to indirect and hybrid position/force control. Usually ignored in literature while considering dexterous manipulation, the position and movement of the arm play a very important role. Many in-hand manipulation tasks cannot be realized without a proper movement of the arm. One typical example is the rotation of the manipulated object relative to the palm without moving the fingers thanks to inertial and gravitational effects. Besides, arm movement is also an important factor contributing to the appearance of the grasping gestures. In this thesis, the movement of the grasped object under gravitational effect was analyzed and a grasping strategy was elaborated. In addition to this, some mechanical constraints (tenodesis effect in particular) contributing to the human natural gestures were deciphered and such natural gestures were reproduced on an anthropomorphic arm-hand robot in redundant grasping situations.

Robots should offer a human-like level of dexterity when handling objects if humans are to be replaced in dangerous and uncertain working environments. This level of dexterity for human-like manipulation must come from both the hardware, and the control. Exact replication of human-like degrees of freedom in mobility for anthropomorphic robotic hands are seen in bulky, costly, fully actuated solutions, while machine learning to apply some level of human-like dexterity in underacted solutions is unable to be applied to a various array of objects. This thesis presents experimental and theoretical contributions of a novel neuro-fuzzy control method for dextrous human grasping based on grasp synergies using a Human Computer Interface glove and upgraded haptic-enabled anthropomorphic Ring Ada dexterous robotic hand. Experimental results proved the efficiency of the proposed Adaptive Neuro-Fuzzy Inference Systems to grasp objects with high levels of accuracy.

Although much more complex and maneuverable than their predecessors, today's anthropomorphic robotic hands still cannot match the dexterity of human hands. While most of these limitations are caused by inadequate sensor and control systems, the use of large, heavy, and stiff actuators can also contribute to dexterity problems. If we expect robotic hands to interact with humans and human objects, joint actuators must allow a compromise of strength and compliance. Piezoelectric (PZT) actuators exhibit a high back driveability which could facilitate this compromise. Although they have low displacement and force output, they are useful in fine control applications. When combined with a DC motor, PZT actuators can produce precise, delicate movements in robotic hands. To develop the novel DC-PZT hybrid system, the force and displacement capabilities of PZT actuators were first characterized with a simple one degree of freedom system. The data from this characterization was analyzed and used to develop a one degree of freedom thumb using a hybrid DC motor/PZT actuator system. To study system performance, a simple position control scheme was implemented for the DC motor and PZT actuators. The experimental results suggest that current PZT actuators, even when combined with a DC motor, cannot produce enough thumb tip force to mirror the functionality of the human hand. That said, improvements to the actuator could make PZT-actuated hands a future possibility.
