A Survey of Robotic Hand- Arm Systems

From the last three decades creating human robotic hand replica with enhanced capabilities is of concern and lot of efforts have been put into it. This paper focuses on understanding the different techniques that are used for human robot interaction in robotic hand arm systems. Diversification is stated in areas of human and robotic hand interaction, the degrees of freedom, the grasping ability, number of fingers and materials used for the hand. The flexibility of grasp is compared in terms of Degrees Of Freedom (DOF) and the number of finger end effectors. The controlling method is either through sensor based or gesture controlled or simulation based or pre-defined positions
