  • Publication number: 20180243901
    Abstract: A robot system includes a robot main body, memory part configured to store information for causing robot main body to perform given operation, as saved operational information, motion controller configured to control operation of robot main body by using saved operational information as automatic operational information for causing robot main body to operate, and an operation correcting device configured to generate, by being operated, manipulating information for correcting operation of robot main body during operation. Motion controller controls robot main body to perform an operation corrected from operation related to automatic operational information in response to a reception of the manipulating information while robot main body is operating by using automatic operational information. Memory part is configured to be storable of corrected operational information for causing robot main body to perform corrected operation as saved operational information, when robot main body performs corrected operation.

  • Patent number: 8788087
    Abstract: A robot arm having a distal end to which a wrist axis is rotatably provided; arm drive unit, each configured to move the robot arm; a wrist axis drive unit configured to rotate the wrist axis; and a robot control unit configured to control the arm drive unit and wrist axis drive unit. The robot control unit is configured to control the arm drive unit to move the distal end of the robot arm to bring a contact member attached to the wrist axis into contact with an instruction target, thereby detecting a posture of the robot arm and an angular position of the wrist axis when the wrist axis begins to be angularly displaced due to the contact between the contact member and the instruction target, thus determining a position of an instruction point.

  • Patent number: 8641351
    Abstract: A robot control unit that turns off a holding unit for a plate member, while the plate member is placed on an end effector, and lower the end effector, by a predetermined distance, from an initial position higher than a preset temporary placing position toward the temporary placing position. Then the robot control unit switches the holding member, from an OFF state to an ON state, while the end effector is stopped, and determines whether the plate member is held by the holding unit, with a holding-state detection unit. When the plate member is held by the holding unit, the robot control unit turns off the holding unit while further lowering the end effector by the predetermined distance. When the plate member is not held by the holding unit, the robot control unit detects a position of the end effector at this point of time, as a normal placing position.

  • Patent number: 8121732
    Abstract: A target position detection apparatus for a robot includes: a robot including an arm configured to be freely moved in at least two directions of X and Y axes, the arm having a wrist axis provided at a distal end of the arm and configured to be freely moved in a horizontal direction, and the wrist axis being provided with an end effector; and a control unit adapted for driving a memory to store a teaching point therein and controlling an operation of the robot such that the end effector will be moved toward the teaching point stored in the memory.

  • Patent number: 7558646
    Abstract: The present invention has a communication connection means (21) which mutually connects communicatably control units (Ca, Cb) for individually controlling operations of robots (Ra, Rb) to constitute a network, input means (37a, 37b) which are respectively installed in the control units and input operation instructions of the robots, and timing signal generation means (69a, 69b). The control units are selectively set to any one of an independent function execution mode, a master function execution mode, and a slave function execution mode, and among the control units, the control unit (Ca) to perform a master operation is set to the master function execution mode, and the residual control unit (Cb) is set to the slave function execution mode, and by correcting a minimum interruption period (Ts(b)) of the slave side control unit (Cb), a control time (ta11, ta12, ta13) to the master robot (Ra) of the master side control unit (Ca) is delayed by a predetermined time (T) to perform the cooperative operation.
