A robot system includes a robot, a moving body, a determination circuit, a calculation circuit, and a control circuit. The robot includes a mount and a first arm. The determination circuit is configured to determine a lastly moved part of the robot which is lastly moved to make the robot take an operation posture. The calculation circuit is configured to calculate, based on the lastly moved part, an angle between a travel direction of the moving body and an orientation axis of the first arm when the robot in the operation posture is viewed along a height axis of the robot. The control circuit is configured to control the robot to work on a workpiece keeping the robot in the operation posture with the calculated angle while controlling the moving body to move in the travel direction.

Robot system and method for controlling robot

A workpiece detector includes a camera to acquire a two-dimensional image of a search range within which workpieces are disposed. A three-dimensional sensor detects a three-dimensional shape of a three-dimensional detection area. A workpiece extraction section processes the two-dimensional image to extract candidate workpieces. An area setting section sets a three-dimensional detection areas respectively corresponding to the candidate workpieces. A prioritizing section sets an order of priority to the three-dimensional detection areas to give higher priority to one three-dimensional detection area containing more of the candidate workpieces. A sensor control section controls the three-dimensional sensor to detect the three-dimensional shape of each three-dimensional detection area in the order of priority. Every time the three-dimensional shape is detected, a workpiece detection section searches the workpieces based on the detected three-dimensional shape to detect a pickable workpiece.

A workpiece takeout system includes a robot arm and a disposed-state detector. The robot arm is configured to perform a workpiece takeout operation to take out a workpiece disposed in an area among a plurality of areas. The disposed-state detector is configured to detect a disposed state of the workpiece and is configured to, while the robot arm is performing the workpiece takeout operation to take out the workpiece disposed in the area among the plurality of areas, detect a disposed state of another workpiece disposed in another area among the plurality of areas.

Workpiece takeout system, robot apparatus, and method for producing a to-be-processed material

A robot system includes a container, a disposed-state detector, and a robot arm. The container is configured to accommodate a plurality of to-be-held objects and includes a reticulated portion. The disposed-state detector is configured to detect disposed states of the plurality of respective to-be-held objects disposed in the container. The robot arm includes a holder configured to hold a to-be-held object among the plurality of to-be-held objects based on the disposed states of the plurality of respective to-be-held objects detected by the disposed-state detector.

Robot system and method for producing a to-be-processed material

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.
