Line 6:

The end effector of an assembly line robot would typically be a [[Welding|welding head]], or a [[Spray painting|paint spray gun]]. A [[surgical robot]]'s end effector could be a [[scalpel]] or others tools used in surgery. Other possible end effectors are machine tools, like a [[drill]] or [[milling cutter]]s. The end effector on the [[Canadarm|space shuttle’s robotic arm]] uses a pattern of wires which close like the [[aperture]] of a camera around a handle or other grasping point.

When referring to robotic prehension there are four general categories of robot grippers, these are<ref>{{cite book |last1=Monkman |first1=G.

# Impactive – jaws or claws which physically grasp by direct impact upon the object.

# Ingressive – pins, needles or hackles which physically penetrate the surface of the object (used in textile, carbon and glass fibre handling).

Line 12:

# Contigutive – requiring direct contact for adhesion to take place (such as glue, surface tension or freezing).
