A robotic arm (10) for use with a pharmaceutical unit of use transport and storage system (200) comprises a base plate (14) with a first cam track segment (16) and a second cam track segment (18). A first arm segment (20) is rotatably attached to the base plate (14) and a second arm segment (26) is rotatably attached to the first arm segment (20) and includes a cam track follower (110) that engages with the first and second cam track segments (16, 18) to guide the movement of the second arm segment (26). A platform (36) is secured to an end of the second arm segment (26) and is adapted to engage a product (214). A series of orientation sprockets (102, 124, 126, 142) and drive chains (148, 150) cooperate to maintain the platform (36) rearwardly oriented as the arm (10) extends from a retracted position to an extended position.
