| Summary: | A human hand is a very complex grasping archtecture which can handle objects of different sizes and shapes. When such
important feature is lost, the replacement artificial hand should capable to imitate the real hand capability, hence ensuring user comfort,
This paper proposes a system to control multi finger grippers with emphasis on the finger tips and finger joints. It consists of two modules
namely smart glove in master module and hand gripper in slave module. The former responsible to infer user control command while the
latter controlling the robot arm movement according to the user instruction. In master module, the system comprises combination of flex
sensors and force sensor mounted under the glove to determine kgers bending angle and the force value. Such information is useful to
control the artificial gripper for grasping objects in various shapes with right amount of force. In the slave module, the robot arm consist
combination of power window motor and servos to initiate the arm and finger movement. Experimental results have shown the feasibility
of the proposed system for controlling the artificial gripper and arm precisely according to the user command. |
