what is an industrial robot? - ANSWER general-purpose, programmable machine possessing certain anthropomorphic characteristics, the most obvious of which is a mechanical arm that is used to perform various industrial tasks. what are the five joint types used in robotic arms and wrists? - ANSWER The five joint types are the following: (1) Linear joint (type L joint), in which the relative movement between the input link and the output link is a translational sliding motion, with the axes of the two links being parallel; (2) orthogonal joint (type O joint), which is also a translational sliding motion, but the input and output links are perpendicular to each other during the move; (3) rotational joint (type R joint), which provides rotational relative motion, with the axis of rotation perpendicular to the axes of the input and output links; (4) twisting joint (type T joint), which also involves rotary motion, but the axis of rotation is parallel to the axes of the two links; and (5) revolving joint (type V joint), in which the axis of the input link is parallel
