Robot grippers are end effectors in robotic arm systems. Robot grippers are the main units that directly contact the working area of the robotic system. Basically a robot gripper functions as the hand of the robotic system. The position and orientation of the robot gripper is controlled by the robotic arm and depending on the intended operation grips the target object or releases it.
Robot grippers are generally used in pick and place applications. There are different gripper types depending on the object to be gripped or the desired grip power or speed.
