Robots facilitate the loading and unloading of parts at production machines through the use of specialized industrial robots designed to perform repetitive or hazardous tasks.12

To execute these operations, a robot is equipped with an "end effector"—typically a two- or three-finger gripper—that is specifically engineered to grasp parts based on their unique geometry. These robots operate by following stored sets of instructions, moving their arms and wrists through defined paths to transfer components between locations, such as moving parts from a conveyor to a machine.12

In more advanced setups, "intelligent" robots utilize tactile or visual sensing devices mounted on their end effectors to determine the proximity and orientation of the objects they are manipulating. This automation is particularly valuable in manufacturing environments where the work is repetitive, involves heavy or awkward components, or occurs in conditions that are hazardous or uncomfortable for human workers.12
