  • Publication number: 20200306967
    Abstract: A programming assistance device includes a program storage unit that stores a first program comprising a first set of time series jobs and stores a second program comprising a second set of time series jobs. Each job of the first program defines at least one operation of a first robot, and the first program is configured to be performed along a shared time line. Additionally, each job of the second program defines at least one operation of a second robot, and the second program is configured to be performed along the shared time line.

  • Publication number: 20190160665
    Abstract: A control system for an actuator includes a non-transitory computer readable medium storing a database in which first information, second information and third information are stored and correlated with each other, and processing circuitry that performs machine learning based on the first information, the second information and the third information stored in the database. The first information is associated with a rotational speed of a reducer in the actuator, the second information is associated with a torque acting on the reducer, the third information indicates a concentration of iron powder in grease in the reducer, and the machine learning builds a concentration estimation model indicating a relationship between the first information, the second information and the third information.

  • Publication number: 20180264651
    Abstract: A control system 1 includes a first controller, and a second controller. The second controller includes a program storage module that stores two or more coordinate conversion programs, and a control processing module 240 that acquires program designation information for designating one of two or more coordinate conversion programs from the first controller. Additionally, the control processing module may acquire a first operation command in the coordinate system for the first controller from the first controller, and convert the first operation command to an operation target value of two or more joint axes of a multi-axis robot using the coordinate conversion programs according to the program designation information. Driving power according to the operation target value may be output to the joint axes.

  • Patent number: 9346630
    Abstract: A robot system includes a first conveyor, a second conveyor, a robot, and a controller. The first conveyor conveys a plurality of kinds of workpieces. The second conveyor conveys workpiece groups each including a combination of the workpieces. The controller controls the robot, and includes a situation acquirer, a determiner, and an instructor. The situation acquirer acquires a situation in a predetermined monitor area on the first and second conveyors. The monitor area is set based on a movable range of the robot. Based on the situation, the determiner determines whether one of the workpieces on the first conveyor in the monitor area is a missing workpiece of one of the workpiece groups in the monitor area. The instructor instructs the robot to hold the one workpiece and to transfer the one workpiece from the first conveyor to the second conveyor.

  • Publication number: 20160083199
    Abstract: A robot system includes a conveyor, a robot, and a controller. The conveyor is configured to convey a workpiece. The robot includes a plurality of holders configured to hold the workpiece. The controller is configured to control the robot to hold the workpiece conveyed on the conveyor and transfer the workpiece to a predetermined place using at least one holder among the plurality of holders. The controller includes a divided area setter and an allocator. The divided area setter is configured to set a plurality of divided areas on the conveyor in a width direction of the conveyor, and is configured to store the plurality of divided areas in a storage. The allocator is configured to allocate the plurality of holders respectively to the plurality of divided areas so as to hold the workpiece when the workpiece is conveyed in the plurality of divided areas.
