A parallel robot includes a fixed platform, a movable platform, a plurality of control arms, a rotation arm, a plurality of first actuators, and a second actuator. The control arms are rotatably connected to the fixed platform and the movable platform, respectively. Opposite ends of the rotation arm are universally rotatably connected to the fixed platform and the movable platform, respectively. The first actuators are to respectively move the control arms. The second actuator is to drive the rotation arm to rotate around the center axis of the rotation arm. Each control arm includes a first transmission unit including a transmission member. Each first actuator includes a transmission gear to engage the transmission member of the control arm.
