A robot arm assembly includes a support arm, and the support arm includes a mounting base and a connecting portion defining a hollow portion. The robot arm assembly further includes a first arm, a second arm, a first input shaft, a second input shaft coaxial with and rotatable relative to the first input shaft, a first gear transmission mechanism coupled to the first input shaft to rotate the first arm, a second gear transmission mechanism coupled to the second input shaft to rotate the second arm, and a first backlash adjust mechanism to adjust the positions of the connecting portion, of the first and second input shafts relative to the mounting base, and providing the adjustment of the backlash between the first input gear pair and the second input gear pair. |
