Abstract: Embodiments of the present disclosure provide an apparatus for determining oil leakage of a gearbox and an associated robot. The apparatus comprises a swellable ring arranged surrounding an output shaft of a motor coupled to the gearbox, the swellable ring, when contacting oil, swells to apply a radial force to the output shaft; and a controller configured to detect the oil leakage by detecting at least one of the following caused by the applied radial force: a torque change on the output shaft, or a change in a current for driving the motor. With the apparatus, before oil leaks into the motor, the user already knows or the motor has already been stopped. In this case, the robot using the apparatus can be operated more safely.

Abstract: Present disclosure provide an apparatus for holding cables of a robot and a robot. The apparatus comprises a body extending along an axis and comprising a circumferential wall to space the cables arranged in the body from a first part of the robot; and a slit formed on the circumferential wall across an entire length of the circumferential wall along the axis, the slit adapted for the cable to pass through radially to allow the cables to be arranged in the body. With the slit formed across the entire length of the circumferential wall along the axis, the cables can be easily arranged in the body radially through the slit. In this way, the cables can be arranged in the apparatus without having to remove the large connector, thereby improving assembly efficiency. In addition, since the connector does not need to be removed, the connection performance is also improved.
