A robot system includes a robot arm, one or more actuators that are provided in the robot arm to drive the robot arm, a sensor unit that detects an external force applied to at least one of the robot arm and the actuators, and a controller that controls an operation of each of the actuators and limits a torque instruction value for each of the actuators on the basis of a detection result of the sensor unit.

Robot system, control device of robot, and robot control device

To enable a recovery control program to be executed quickly by a robot controller without needing to equip the robot controller with a large-capacity storage device, provided is a robot system, including a first robot controller for controlling a first robot. The first robot controller includes a posture information obtaining unit for obtaining information indicating a posture of the first robot when an anomaly occurs in the first robot. The robot system further includes a recovery control program generating unit for generating, by computing, based on the posture of the first robot, a recovery control program for changing the posture of the first robot to a given standby posture.

Robot system, robot management computer for a robot system, and method of managing a robot system

A robot apparatus includes a robot main body, a distance determining section, an order determining section, and an operation controlling section. The robot main body transfers a plurality of to-be-processed objects in order so as to subject every predetermined number of the to-be-processed objects to processing, and includes a robot arm and a robot hand. The distance determining section determines an entire transfer distance of each of the to-be-processed objects. The order determining section determines a transfer order of the to-be-processed objects based on a determination result of the distance determining section so that every predetermined number of the to-be-processed objects has uniform transfer time. The operation controlling section controls operations of the robot arm and the robot hand so as to transfer the to-be-processed objects in accordance with the transfer order determined by the order determining section.

Robot apparatus

This robot hand includes a first finger portion and a second finger portion being relatively movable in a direction in which an object to be grasped is grasped and bar-shaped claw members fixed to the first finger portion and the second finger portion. A plurality of claw members are fixed in parallel to at least either the first finger portion or the second finger portion.

Robot hand, robot system, and method for manufacturing workpiece

A robot system according to an embodiment includes a robot a switching determination unit and a rearrangement instruction unit The switching determination unit performs determination of switching between the operation of transferring the workpiece and the operation of rearranging the workpiece based on the state of transferring the workpiece by the robot The rearrangement instruction unit instructs the robot to rearrange the workpiece.

Robot system

A workpiece in a container is held by a robot based on a result of detection of shape information in the container by a shape sensor, a holding condition of the workpiece held by the robot is inspected by an inspection device, and the workpiece is transferred to a subsequent step by the robot when the inspection device has determined that the holding condition of the workpiece is acceptable. When the inspection device has determined that the holding condition of the workpiece is unacceptable, the held workpiece is placed on a temporary placement table, the shape of the workpiece is again detected by detecting the workpiece using the shape sensor, and the workpiece is held and transferred to the subsequent step by the robot based on a result of the detection.

Robot system and transfer method

A robot system includes a robot. A robot control device is configured to control an operation of the robot, and includes a workpiece shape memory configure to store a shape of workpieces. A shape sensor is configured to detect shape information about the workpieces. A target workpiece detector is configured to detect a graspable workpiece based on the shape information detected by the shape sensor. A grasping information memory is configured to store a grasping position indicating which portion of the graspable workpiece is to be grasped by the robot. A grasping operation controller is configured to control the robot to grasp the graspable workpiece detected by the target workpiece detector and to pick the grasped workpiece. A disturbing operation controller is configured to control, if no graspable workpiece is detected by the target workpiece detector, the robot to perform a workpiece disturbing operation.

Robot system and workpiece picking method

A robot according to an embodiment includes an arm, a strain sensor, one or more actuator, and a sensor fixing jig. The strain sensor includes a piezoelectric body that has a natural frequency higher than a natural frequency of a structural material forming the arm. The one or more actuators are provided in the arm to drive the arm. The sensor fixing jig is provided in a base of the actuator, among the actuators in the arm, closest to a base end of the arm. The strain sensor is provided in the sensor fixing jig.
