<p>A coating end effector (48) may be carried by a robot (22). A plasma spray head (44) is mounted by a joint (46) to the end effector (48). A plurality of actuators (80,82,84) couple the end effector (48) and plasma spray head (44) to provide articulation of the joint (46). The apparatus may be used to coat an airfoil cluster (200) of a gas turbine engine. The coating may include passing the head (44) between the airfoils (202,204).
