According to various aspects, a controller for an automated machine may include: one or more processors configured to: obtain a message from a further automated machine in accordance with a communication protocol, the message including a first result of a first sensing process that the further automated machine performs; and determine an assessment of the automated machine based on the first result and based on a second result of a second sensing process that the automated machine performs.

A horizontal articulated robot including a base; one or more arms, attached to the base so as to be capable of rotating horizontally; a ball screw spline shaft that is disposed at an end of the one or more arms and that supports a workpiece at one end of the ball screw spline shaft; a ball screw nut through which the ball screw spline shaft passes and which is driven; and two ball spline nuts configured to support the ball screw spline shaft passing through the ball spline nuts, respectively, on both sides of the ball screw nut interposed therebetween in a longitudinal axis direction. At least one of the ball spline nuts drives the ball screw spline shaft about the longitudinal axis with respect to the arms.

A method for charging a service robot and a service robot are disclosed. The method comprises: collecting an audio signal generated by a sound source of a charging pile; determining a direction of the sound source according to the collected audio signal; controlling a robot main body to move toward the direction of the sound source, to shorten a distance between the robot main body and the charging pile; judging whether the infrared receiver array has received an infrared pulse signal emitted by the infrared emitter array of the charging pile; and when the infrared receiver array has received the infrared pulse signal, controlling the robot main body to move toward a direction of the charging pile according to the infrared pulse signal, to engage a charging component of the robot main body with a charging contact element of the charging pile.

Disclosed are a method and a system for charging a robot. A method for charging a robot according to an embodiment of the present disclosure includes monitoring a battery level of a first robot which is providing a service, determining a charging robot for charging the first robot, from a plurality of second robots, when a battery level of the first robot falls below a first threshold level, and transmitting an instruction to move to a target position to the determined charging robot, in which determining the charging robot comprises determining the charging robot based at least partly on distances between the first robot and the second robots and battery levels of the second robots. Embodiments of the present disclosure may be implemented by executing an artificial intelligence algorithm and/or a machine learning algorithm in a 5G environment connected for Internet of Things.

A deterioration degree of a robot body is precisely evaluated. A robot control device 300 includes: a drive control unit 309 controlling operation of a robot body 200; a detection unit 310 detecting a signal used for analysis of a feature amount quantitatively indicating a deterioration degree of the robot body 200 deteriorated over time as the robot body 200 is operated; a determination unit 304 determining whether a data section of the signal includes a constant speed section equal to or greater than a given section; a normalization unit 305 normalizing a signal in a non-constant speed section when the data section of the signal does not include the constant speed section equal to or greater than the given section; an analysis unit 307 analyzing the feature amount; and an estimation unit 308 estimating a remaining life of the robot body 200 based on the feature amount.

Provided is an arm fixing device that includes: a bracket having close-contact surfaces that are brought into close contact with a mounting surface provided in a supporting member, and a mounting surface provided in an arm or a link for transmitting drive force to an arm, also having one of a screw hole or a through hole that is formed to penetrate each of the close-contact surfaces at a position corresponding to a position of the other of a screw hole or a through hole provided in each of the mounting surfaces, and bridged over the mounting surfaces such that each of the close-contact surfaces is brought into close contact with a corresponding one of the mounting surfaces; and a fastener that penetrates the through hole and is fastened to the screw hole.

A device including a work history DB is configured to store work data of an apparatus such as a speed reducer mounted on a manufacturing robot, and an abnormality determination circuit is configured to determine an abnormality of the apparatus according to the work data to notify a user of the abnormality having been determined. The device also includes a maintenance record creation circuit configured to create a maintenance record indicating that maintenance has been made for the abnormality according to the work data. The maintenance record is automatically created, so as to reduce a workload of the user upon the creation of the maintenance record. This can prevent an error upon creation such as failing to create the maintenance record or making clerical errors.
