This paper presents the design of Robotic arm which simulates the human hand movement to grip an object. The robotic arm is Arduino controlled robotic arm hence it can be implemented to a robot which can analyze hazardous area do a material handling. [1] In order to examine those torque characteristics, we consider a model of humanoid robot arm and simulate typical object lifting and transferring tasks by using the robot arm. [2] The majority of current robotic hands does not completely replace the functionality of a hand and cannot be used in environments which are designed for the use of human hand. This paper concludes with some possible applications of 4 D.O.F robotic arm mechanism based on type of end effector attached to the robotic arm.
