    摘要: A robot (1) includes a lower arm mechanism (5) having a first parallel link structure, an upper arm mechanism (12) having a second parallel link structure, a base portion (3) forming a lower side part of the first parallel link structure, a wrist portion (15) forming a distal side part of the second parallel link structure, an intermediate connection portion (11) forming an upper side part of the first parallel link structure and a proximal side part of the second parallel link structure, and an upper arm biasing unit (19) for applying a biasing force against a rotating operation in a direction that the wrist portion (15) descends to an upper arm (14) configuring a lower side part of the second parallel link structure. According to the robot (1), the range of the portable mass of an object can be expanded without enlarging an arm drive motor and declining an arm operation speed.
