Example implementations may relate to a robotic system configured to provide feedback. In particular, the robotic system may determine a model of an environment in which the robotic system is operating. Based on this model, the robotic system may then determine one or more of a state or intended operation of the robotic system. Then, based one or more of the state or the intended operation, the robotic system may select one of one or more of the following to represent one or more of the state or the intended operation: visual feedback, auditory feedback, and one or more movements. Based on the selection, the robotic system may then engage in one or more of the visual feedback, the auditory feedback, and the one or more movements.

The invention relates to a system and method for changing liners of a mill, the configuration of which allows the automated robotic manipulation of liners of mills for ore grinding in comminution processes. The configuration and operation of the system allows the task of manipulation to be improved, having a greater degree of freedom and/or flexibility in its movements, thereby providing a greater degree of certainty and efficiency to the method and thus optimising the time that the mill is halted for maintenance, and also preventing the risks to which maintenance staff may be exposed. The system comprises at least one support structure, at least one system for supplying and moving liners, at least one robotic manipulator system for manipulating the liners, at least one liner manipulation tool, at least one artificial vision system, and at least one control system.

A robot includes a filming unit that films a periphery, and a movement control unit that controls a distance from a filmed target object in accordance with a size of the target object. The robot may further include an operation control unit that controls an operation of a head portion, and a recognizing unit that recognizes a face of the filmed target object. The operation control unit may control the operation of the head portion so that a line of sight of the head portion reaches an angle of looking up directed at the face of the target object. The movement control unit may control the distance from the target object in accordance with a height of the target object.

An object recognizer recognizes a position and an attitude of a target object based on data measured by a sensor. A safe distance calculator calculates a distance from the target object to a certain object which is other than an object manipulation apparatus and the target object. A manipulation controller controls the pickup device based on the position and the attitude of the target object, and based on the distance from the target object to the certain object. When there are a plurality of target objects to be selected by the object manipulation apparatus, the manipulation controller selects one of the target objects having distances to the certain object longer than a predetermined threshold, and manipulates the selected target object using the pickup device.

[Problem] To provide an agent robot control system, agent robot system, agent robot control method, and recording medium, which are capable of assisting in optimal shopping in real storefronts and online storefronts. [Solution] Provided is an agent robot control system, comprising an acquisition unit which acquires a purchasing master list which shows a user's purchase merchandise candidates, and a control unit which generates a purchasing execution list for recommending, from the purchasing master list, purchases for select merchandise to be performed at real storefronts and for recommending purchases for other merchandise to be performed at online storefronts.

A robot control device includes: a measuring unit to measure a robot control state indicative of a position and a posture of the robot; a work area setting unit to store, for each of work processes, a work area that is defined by work movement of the worker between a start and an end of each of the work processes and includes a space a body of the worker occupies and to set the work area corresponding to the work process currently carried out by the worker based on a signal specifying the work process currently carried out by the worker; and a robot command generator to generate a motion command for the robot based on the work area and the robot control state. The generator varies the command for the robot based on whether the robot is present in the work area.

A robot operation evaluation device includes: an operational state calculator for calculating an operational state of an evaluation region that is a movable region of a robot, based on an operational state of the robot; a shape-feature quantity calculator for calculating a shape-feature quantity depending on an operation direction of the evaluation region corresponding to the operational state calculated; and an evaluation value calculator for calculating an evaluation value representing a risk degree of the operational state of the evaluation region with respect to the operation direction, based on the shape-feature quantity.

A robot hand is designed to open or close fingers using a linear actuator disposed in a housing. The robot hand has linear motion shafts extending from inside to outside the housing through guide holes formed in a wall of the housing. Each of the fingers includes a base portion and a tip portion. The base portions are secured to the linear motion shafts outside the housing. The tip portions are bent inwardly from the base portions in directions in which they approach each other and then extend toward tips of the fingers. A sealing member is disposed between each of the linear motion shafts and a corresponding one of the guide holes to hermetically isolate the inside of the housing from the outside thereof. This structure achieves an increased degree of sealing of the housing and is capable of having an increased opening or closing stroke of the fingers.

A controller for a parallel link mechanism includes a drive control unit that controls driving of a parallel link mechanism and a command section that gives a command for controlling an actuator to the drive control unit. The command section includes a natural frequency prediction unit that calculates a predicted value string of a natural frequency changing depending on the position of an end effector for each interpolation position of the end effector by using a dynamic model that simulates a mechanical system from a base to a link joint of the parallel link mechanism with a translational spring and simulates a mechanical system from the link joint to the end effector with one rigid body. The drive control unit includes a filter that changes a frequency component to be suppressed for each interpolation positions according to a predicted value string at each interpolation position of the end effector.
