Abstract : Dexterous Hand Master (DHM) is one of exoskeletal controlling devices. The exoskeletal devices are used to translate the movement of the body that wears the exoskeleton device to another system. As the other exoskeletal devices, the (DHM) is used to measure the position of the hand and display it either on the other environment like robotic or in virtual environment. The signal that came from the hand is analog, but when these signals enter to PC must pass through many IC's that convert it to digital. These IC's are multiplexer and analog to digital (ADC) circuits which are used to translate the data to PC from hand. The encoder and decoder circuit are used to transfer the data that comes from the PC to the hand to perform the haptic signal to the user. The slave part of the hand master is using a virtual reality application to observe the motions and the positions of the user's fingers in the virtual environment. A haptic signal is generated and loaded back to the hand master when the virtual hand is in touch with an object in the virtual environment, this signal is generated by a decoder circuit. VISUAL BASIC V 6.0 is used to develop the software that controls the operation of the interface circuit, processing the obtained data that came from the hand, and draw the virtual hand. There are 8 Degrees of Freedom (DOF) that allow wide numbers of different hand postures, these 8 DOF comes from the eight sensors that attached in the glove. The weight of the proposed DHM exoskeleton structure is about 150g. The connecting weirs had a length of 1.5 m, this length providing a large work space for Glove user.
