Abstract:
Provided is a parallel link robot which has increased rigidity and which can be reduced in size. The parallel link robot includes: a base (1); a movable portion (2); a plurality of link portions (5) connecting the base (1) and the movable portion (2); and a plurality of actuators (6) for driving the plurality of link portions (5), wherein each of the plurality of actuators (6) is a linear actuator (6) supported on the base (1) to be rotatable about a predetermined axis (A1) and has a main body portion (8) and a shaft portion (7) for linearly moving relative to the main body portion (8), and each of the plurality of link portions (5) has a driving link (3) supported on the base (1) to be rotatable about a predetermined axis (A2) and connected to the linear actuator (6) and a driven link (4) connecting the driving link (3) and the movable portion (2). When the linear actuator (6) extends and contracts, the driving link (3) rotates relative to the base (1) about the predetermined axis (A2) of the driving link (3).
