Abstract: Method for determining a lock type of a lock device. In the method, a group of raw data of a group of lock devices is collected from a group of sensors respectively. Here the group of lock devices are respectively mounted to an object at a group of positions, and the group of lock devices belong to at least one lock type of a plurality of lock types. A group of probability distributions are obtained based on the group of raw data. Here a probability distribution in the group of probability distributions is associated with a lock device in the group of lock devices and probabilities of lock types to which the lock device belongs. A lock type of the lock device is determined based on the group of probability distributions.

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.

Abstract: Methods, apparatuses, systems, and computer readable media for managing a path of a robot system. The systems include comprises an arm which has a joint for rotating the arm. In the methods, a real path of a tip of the robot system is obtained during directing a movement of the tip to follow an ideal path. A path deviation is identified between the real path and the ideal path. A transmission error of the joint is determined based on the path deviation and kinematic data associated with the movement and a plurality of rotations of the joint respectively at a plurality of time points during the movement.

Abstract: Methods and devices for diagnosing a robot. The method includes obtaining a first signal generated by a rotating component of the robot during operation of the robot. The first signal includes motion information of the rotating component. The first signal is preprocessed to filter out a part of the motion information in the first signal. The preprocessed first signal or spectrum information about the preprocessed first signal is sent to a server for diagnosing the robotU. A second signal is received from the server, wherein the second signal includes diagnostic information indicating whether a sub-component of the rotating component has a failure.

Abstract: It is therefore an objective to provide an object multi-perspective inspection apparatus and a method therefor. The apparatus includes an image capture device; an inspection site and at least two reflection devices, being arranged for reflecting simultaneously to the image capture device at least two different side views of the object located in the inspection site; wherein: the image capture device has a field of view including the at least two different side views of the reflection. By introducing reflection devices into the inspection apparatus to enable the image capture device to “see” the part from multiple views at once, multiple surfaces can be inspected at once, in one image frame, without having the need to reposition the reflection device, the camera and/or the object for every single surface. There are more than one reflection devices placed in the camera's field of view to assist the inspection process by exploiting otherwise hidden surfaces of any given solid object. The effort inspecting every single part form multiple sides is reduced. Therefore, the period of the inspection cycle time can be reduced and inspection on the level of multi-surfaces becomes possible increasing overall quality.

Abstract: Systems, devices, and methods for time calibration. The method can include, in responses to receiving sensing data which indicates a deviation of a tool from an object to be operated by a robot with the tool, triggering the robot to perform a plurality of transformations. Each transformation causing the tool to contact the object at a reference position; determining joint positions of a joint of the robot holding the tool or the object after the plurality of transformations; and determining a position relationship between the tool and the robot at least partially based on the joint positions and the reference position.

Abstract: Embodiments of the present disclosure provide an apparatus and a method for operating a pair of twistlocks and an associated robot. The apparatus comprises a first component adapted to clamp a first twistlock to allow the clamped first twistlock to be removed from a container; and a second component arranged adjacent to the first component and adapted to clamp a second twistlock to allow the clamped second twistlock to be removed from a container; or receive the first twistlock released from the first component to allow the first component to clamp the second twistlock. With the first and second components, the pair of twistlocks, especially mid-type twistlocks, can be operated more quickly with less operation steps. In this way, the operation efficiency for operating the mid-type twistlocks can be significantly improved with lower costs.

Abstract: An apparatus for determining oil leakage of a gearbox and an associated robot. The apparatus includes a base arranged between the gearbox and a motor coupled to the gearbox. The base can be made of a oil-absorbing material such that a volume of the base changes when the base contacts oil. The apparatus also includes a signal generator coupled to the base and configured to cause an electrical signal or a change in a physical property of the signal generator in response to a change in the volume of the base. The apparatus also includes a controller coupled to the signal generator and configured to detect the electrical signal or the change in the physical property and to determine the oil leakage in response to a detection of the electrical signal or the change in the physical property.
