Abstract
A parallel link robot () provided with a base (), a moving part (), three links (to) coupling the base and the moving part and having respectively single degrees of freedom with respect to the base, and three actuators (to) respectively driving the links, each of the links comprised of a drive link (to) coupled with the base and two driven links (toto) coupling the drive link and the moving part and parallel to each other, and further provided with a posture changing mechanism () which changes a posture of an element () attached to the moving part, an additional actuator (to) arranged between the two driven links of at least one link in parallel to these driven links, and a power transmission shaft () which extends coaxially from the additional actuator and transmits rotational drive force to the posture changing mechanism. Due to this, it is possible to increase the degrees of freedom without reducing the possible region of operation and the acceleration/deceleration performance.
