A robot arm includes a first shaft housing, a first driving mechanism, a second driving mechanism, a cable pass-through assembly and a cable assembly. The first shaft housing is hollow shaped, and includes a housing, a first mounting base and a second mounting base mounted on the housing. The first driving mechanism is mounted on the first mounting base. The second driving mechanism is mounted on the second mounting base. The cable pass-through assembly includes a first cable tube and a second cable tube. The cable assembly electrically connects with the first driving mechanism and the second driving mechanism. An axis of the first cable tube overlaps with an axis of the first mounting base. An axis of the second cable tube overlaps with an axis of the second mounting base. The cable assembly passes through the first cable tube and the second cable tube.
