Abstract: Embodiments of the present disclosure provide a robot. The robot arm link includes a first arm link; a hollow shaft extending along a first axis thereof and coupled to the first arm link; a first stage reduction assembly coupled to a power source of the robot; and a second stage reduction assembly comprising: an input coupled to an output of the first stage reduction assembly and adapted to rotate about a second axis offset from the first axis; and an output coaxially arranged on a periphery of the hollow shaft and adapted to engage with the input to cause a rotation of the first arm link via the hollow shaft.

Abstract: Methods for managing a robot arm are disclosed. In one method, during a movement of the robot arm in an axis thereof, a signal collected by a sensor equipped at a frame of the robot arm is received. A change in strength of the received signal is detected, where the change is caused by an offset between a position of a reference mark equipped at the robot arm and a position of the sensor. An original point of the axis of the robot arm is determined based on the detected change. Further, robot systems, apparatuses, systems, and computer readable media for managing a robot arm in the robot systems are disclosed. The original point of the axis of the robot arm may be determined without a dedicated calibrating tool, and then the robot arm may be calibrated based on the original point accurately.

Abstract: A ring seal and a robot. The ring seal includes an outer circumferential wall and an annular portion. The outer circumferential wall extends in an axial direction of the ring seal. The annular portion extends from a side of the outer circumferential wall toward an interior of the outer circumferential wall in a radial direction of the ring seal. As viewed in a cross section taken along the radial direction, the annular portion and the outer circumferential wall form an L shape.

Abstract: A ball screw spline assembly includes: a ball screw spline including a first nut including a first mounting surface adapted to receive a first fastening element for installing the first nut to a housing; a second nut including a second mounting surface adapted to receive a second fastening element for installing the second nut to the housing; and a shaft passing through the first nut and the second nut; the housing including a first portion and a second portion, the first portion extends in a direction substantially parallel to the shaft, and the second portion extends in a direction substantially perpendicular to the shaft; a connecting plate coupling the second nut to the first portion, the first nut is installed to the second portion; the first mounting surface and the second mounting surface are located within a space defined by the first portion, the second portion and the connecting plate, such that the ball screw spline is integrally installable to the housing. The ball screw spline is integrally installable to the housing, and thus there is no need to remove the spline nut from the shaft when installing and maintaining the ball screw spline. With the bolts adapted to be received within the housing without protruding from the housing, the robot arm including the ball screw spline assembly can be compact since the pulley no longer interferes with the bolts mounted on the spline nut.

Abstract: Embodiments of the present disclosure provide a planetary gearbox. The planetary gearbox includes a housing extending along a first axis; a first coupling member arranged on an inner circumference of the housing; an input component operable to rotate about the first axis; at least one intermediate component, each intermediate component comprising a second coupling member and adapted to be driven by the input component to rotate about a second axis offset from the first axis with the second coupling member engaging with the first coupling member; and an output component coupled to the at least one intermediate component and operable to rotate about the first axis with rotation of the at least one intermediate component, wherein at least one of the first coupling member and the second coupling member comprises a synchronous belt.
