Abstract: A robot system includes a robot, an attraction pad, a sensor, and a controller. The robot includes a hand whose orientation is changeable. The attraction pad is attached to the hand, attracts a workpiece, and holds the workpiece. The sensor is attached to the hand, includes a detection surface, and detects contact between the detection surface and the workpiece. The controller can determine whether the workpiece has been brought into surface contact with the detection surface based on a result of detection made by the sensor and changes the orientation of the hand, until the workpiece makes surface contact with the detection surface, and then makes the attraction pad hold the workpiece.

Abstract: A programming assistance apparatus assists programming with respect to a program that operates two or more devices including at least a robot in parallel. The programming assistance apparatus includes a device extractor, a determiner, and an alerter. The device extractor extracts an identification name of a device to which an operation command is issued per unit of parallel operation based on a description content of the program. The determiner determines whether there is a shared target device, to which operation commands targeting a same device in two or more parallel operations are issued. The alerter outputs an alert when it is determined that there is the shared target device.

Abstract: There are provided a server processing unit 100 which includes a robot control unit 104 for operating a robot body 106 at real time and which provides a network connection function, and a client processing unit 200 connected to the server processing unit 100 via a network 300. A general-purpose public program 501 operating on the client processing unit 200 uses a robot control program unit 403 and a robot monitor program unit 403 which are transmitted from the server processing unit 100. According to the present invention, it is possible to reduce the amount of information transmitted via a communication line, and it is possible to develop an application program of a user's individual specification and an application capable of operating on a network.
