Abstract: The present invention provides a supply apparatus and a receiving apparatus for enabling a user of a production apparatus such as a component mounter, to visually comprehend accurate support information provided from a manufacturer in accordance with the life cycle of the production apparatus, and realize more appropriate production apparatus maintenance. In the support information received by the receiving apparatus, the period after the purchase of the component mounter is displayed in the life cycle, and a list of equipment productivity-related items as well as diagnosis-related items is displayed as support items which are predicted for such life cycle.

Abstract: A waiting time of an automated guided vehicle is substantially eliminated by significantly shortening the communication time of various information, and the transport efficiency of an automated guided vehicle as well as the operating rate of work stations and production lines as a whole are improved, and in addition, the flexibility of an operation control system for the automated guided vehicle is improved. An automated guided vehicle (1) includes a wireless local area network adapter (11) for passing information by radio with an operation control unit connected to the local area network or with another automated guided vehicle, a memory part (12) for storing at least information from the operation control unit or from another automated guided vehicle and information related to the automated guided vehicle itself, and a control part (14) for controlling the wireless local area network adapter and the memory part.

Abstract: The interference avoiding system is provided with an automatic correcting means for correcting a code string programmed for each robot, so that the communication and the waiting processes to check the interference are automatically inserted. In order to check the interference, a target position is transmitted to a checking device immediately before the robot starts operating, thereby to check the interference area by the checking device. Instead, data of the interference area is fed to a robot controller at the start of operation, and the communication is established only when the robot moves from inside to outside the interference area or vice versa. An operation command for the robots is selectively corrected automatically, that is, an operation command to move the robots in a direction not related to the interference direction is not corrected.

Abstract: A robot control apparatus includes a sine wave signal-outputting device, an operating device, a command device for outputting a current value, a substracting device, an electric power amplifying device, and a programmable filter. The outputting device outputs sine wave signals of first and second phases having a phase difference of approximate 90.degree. generated by a position shift of a movable portion of a motor for driving an arm of a robot. The operating device determines the difference between a product of a value corresponding to the first phase signal and a value obtained by first-order differentiating a value corresponding to the second phase signal and a product of a value corresponding to the second phase signal and a value obtained by first-order differentiating the value corresponding to the first phase signal.
