ABSTRACT:
Then an end effecter is used to operate a heavy object, a large bending moment may act on arms of a manipulator to bend them. Consequently, an operating section cannot precisely control positions. Thus, according to the present invention, three arms14are attached to a base section11, each of the arms14being composed of a first link section15having one end connected to a rotating shaft12on the base section11and a second link section17connected to the first link section15via another rotating shaft16. These arms14support an operating section19. The second link section17is connected to the rotating shaft16and to the operating section19using universal joints18aand18b.Direct acting driving means13is composed of a driving shaft13aand a driving source that advances and retreats the driving shaft13a.The driving shaft13ais driven to advance and retreat to move the operating section19to a desired position. In this case, the operating section19is always kept parallel with a particular plane. Loads on the operating section19act in the axial directions of the driving shafts13a.This prevents the driving shafts13afrom being bent or deformed, thus enabling precise positional control.
