A PARALLEL KINEMATIC MANIPULATOR AND A METHOD OF OPERATING THE SAME, INCLUDING PAIRWISE ACTUATORS

摘要

An industrial robot (1) including a parallel kinematic manipulator (2) comprising a stationary platform (2), a movable platform (20), and three arms (6, 7, 10) connecting the stationary platform (2) with the moveable platform (20). Each arm comprising a first arm part (6a, 7a, 10a), a second articulated arm part (6b,7b,10b) 10) and an first actuator (3, 4, 5) for moving the arm (6, 7, 10) in relation to the stationary platform (2). The first arm part (6a) comprises an additional, fourth actuator (21) arranged to tilt the platform (20) around a tilt axis.
