In these times robotic arm is used in several areas analogous as military, defense, medical surgeries pick and place function in artificial automation operations. The Gesture Replicating Robotic arm is a servo controlled robotic arm which replicates the mortal arm gestures in a three- dimensional terrain. The main ideal of this design is to control the robotic arm using mortal gestures. This system replicates the conduct of mortal hands, and the robotic arm moves and performs the task. It's coded in such a way that the demanded conduct for the mortal gesture is done. thus, this model we proposed will be truly helpful.
