Abstract: Robot arm link (100) comprises a body made of non-metallic material, a transmission cable (102) made of conducive material and embedded within the body (101), and at least one connector (103) arranged on the body (101) and coupled to the transmission cable (102), each connector (103) adapted to be electrically connected to a connector (1031) of a further robot arm link (1001) of a same specification, a sensor (301), or a power source (302) of the robot (200). By embedding the transmission cable (102) within the non-metallic material to form the robot arm link (100), there is no need to consider how to route the cable (102) and thus the difficulty of cable routing design can be significantly reduced. Furthermore, the efficiency of robot assembly and maintenance can be increased accordingly. In addition, the cables (102) arranged in the robot arm links (101) are not easily damaged, thereby increasing the service life of the robot.

Abstract: Embodiments of the present disclosure provide a robot. The robot comprises a joint housing and an internal engaging member arranged on an inner surface of the joint housing; a second arm link comprising a flange; and a moving assembly at least partially arranged in the joint housing and comprising an input shaft adapted to rotate about an axis of the input shaft; and at least one intermediate member coupled to the output flange and adapted to be driven by the input shaft to rotate while engaging with the internal engaging member, to cause a relative movement between the first and second arm links. By integrating the relative static parts of the gearbox, such as the joint housing and the output flange to the robot arm links, high connection strength of connections between robot arm links can be achieved in a more cost-efficient and space-saving manner.

Abstract: Embodiments of the present disclosure provide a plastic robot arm link. The robot arm link comprises a body made of plastic material; a connection arranged on the body and adapted to be coupled to a further plastic robot arm link or a transmission part of the robot; and an insertion made of material with a higher strength or stiffness than the plastic material and embedded in the body and/or the connection. By embedding the material with higher strength or stiffness within the body of the robot arm link made of plastic material, the stiffness and strength of the robot arm link can be enhanced. In addition, due to the presence of highly rigid materials, the creep effect of the plastic arm is also significantly reduced, improving the accuracy of the robot.

Abstract: A housing for a plastic gearbox and associated plastic gearbox and a robot. The housing includes a body including an inner engaging portion circumferentially arranged on an inner surface of the body, the inner engaging portion adapted to be engaged with a transmission assembly of the plastic gearbox; and an adjusting mechanism arranged around the body and operable to squeeze the body inwardly to reduce an inner diameter of the body. By using the adjusting mechanism to squeeze the body of the housing inwardly, the fit error between the inner engaging portion and the transmission assembly can be compensated in an efficient way. Furthermore, the adjusting mechanism is a part of the housing and thus the body of the housing which is made of plastic does not need to be too thick, which makes injection molding easier and manufacturing precision improved.
