    • A robot (100) of SCARA type comprises: a base (101); a first arm (102) coupled to the base (101), the first arm (102) being rotatable about a first axis (X1) relative to the base (101) when driven by a first motor (201) arranged in the base (101) via a first transmission mechanism (221); a second arm (103) coupled to the first arm (102), the second arm (103) being rotatable about a second axis (X2) relative to the first arm (102) when driven by a second motor (202) via a second transmission mechanism (222), wherein the second motor (202) is arranged in the base (101) or the first arm (102), and the second axis (X2) is substantially parallel to the first axis (X1); and an operating unit (104) arranged in the second arm (103) and including an operating shaft (801), wherein the operating shaft (801) is movable along a third axis (X3) relative to the second arm (103) when driven by a third motor (203) arranged in the base (101) or the first arm (102) via a third transmission mechanism (223), wherein the third axis (X3) is substantially parallel to the first and second axes (X1, X2), and wherein the operating shaft (801) is rotatable about the third axis (X3) relative to the second arm (103) when driven by a fourth motor (204) arranged in the base (101) or the first arm (102) via a fourth transmission mechanism (224). The load of the robot (100) around the first and second axes (X1, X2) may be reduced, and the heat generated by the motors can be dissipated into the floor or working table quickly.

    • A pressure relief component, a gearbox and a robot. The pressure relief component (100) for a gearbox (200) comprises: a body (101) arranged to close an internal chamber (201) of the gearbox (200) and comprising a groove (1011), the groove (1011) formed on a side of the body (101) adjacent to the internal chamber (201) to form a cavity (1013) in the body (101), wherein the cavity (1013) is in fluid communication with a pressure source providing a predetermined pressure; and an elastic member (102) arranged at an opening of the groove (1011) to isolate the cavity (1013) from the internal chamber (201), the elastic member (102) adapted to deform in response to a pressure difference between the cavity (1013) and the internal chamber(201). With the pressure relief component (100), when the pressure within the internal chamber (201) is increased during the operation of the gearbox (200), the elastic member (102) will deform towards the cavity (1013) because the pressure within the cavity (1013) remains basically constant. The deformation of the elastic member (102) towards the cavity (1013) will increase the volume of the internal chamber (201) and thus reduce the pressure within the internal chamber (201) according to the relationship between the volume and pressure. In this way, the pressure relief component (100) can efficiently reduce the pressure within the internal chamber (201), thereby improve the sealing performance.
