Abstract: Provided is a task teaching method for teaching a task to a robot that includes a gripper unit configured to grip a grip target object and moves the grip target object gripped by the gripper unit, the task teaching method including: a generation step (S701) of outputting, as a reference path, time-series data regarding a position and an attitude of the grip target object when a teacher grips and moves the grip target object and generating teaching data of the robot corresponding to the reference path; and a modification step (S702) of outputting, as an operation path, time-series data regarding a position and an attitude of the grip target object or the gripper unit when the robot is operated using the teaching data before an actual task is executed by the robot and modifying the teaching data such that the operation path matches with the reference path.

Abstract: Provided is a technique for detecting deviation amounts in two directions between a tip of a nozzle of a pipetting device and a target stop position from one image. An imaging device of the present disclosure is an imaging device installed in a pipetting device including a nozzle that aspirates and dispenses liquid and an arm that holds the nozzle and moves the nozzle by a rotation operation. The imaging device includes: a camera that includes an image sensor and a lens; and a pair of mirrors that includes a first mirror having a first reflective surface and a second mirror having a second reflective surface. The pair of mirrors is arranged such that the first reflective surface and the second reflective surface face each other. The pair of mirrors is arranged one by one between the tip of the nozzle and a bottom surface of the arm, on both sides across a plane that includes a rotation axis of the arm and a central axis of the nozzle. The first mirror is disposed closer to the arm than the second mirror, with the first reflective surface facing toward the tip of the nozzle, and the second reflective surface facing toward the camera.

Abstract: In the present invention, device information is collected while real-time performance and high-speed performance of control-related normal communication are maintained. The distributed control system has: a central processing device; a central communication device; multiple terminal communication devices each having at least one controlled device connected thereto; an information storage device; and a network having a tree structure comprising multiple communication paths between the central communication device and the terminal communication devices, between the terminal communication devices, and between the terminal communication devices and the information storage device. The network is provided with a first communication path for connecting the upstream-side communication port of a terminal communication device with the downstream-side communication port of a terminal communication device and for connecting the upstream-side communication port of a terminal communication device with the normal communication port of the central communication device; and a second communication path for connecting between the downstream-side communication ports of terminal communication devices positioned at edges of the network and for connecting the downstream-side communication ports of the terminal communication devices with the device information communication port of the information storage device.

Abstract: An automated analyzer for accurately detecting the position of a nozzle for dispensing, thus being able to highly accurately adjust the position of the nozzle. The automated analyzer includes: dispensing mechanisms including nozzles that dispense a reagent and a specimen, and dispensing arms that move the nozzles; cleaning tanks for cleaning the nozzles; and an automated analyzer control unit that adjusts positions of the nozzles. The automated analyzer analyzes a mixed liquid of the reagent and the specimen, being held in a reaction cell. At the dispensing mechanisms, stop positions of the nozzles are set. The dispensing mechanisms each include an imaging device disposed on the dispensing arms. The automated analyzer control unit takes images of the nozzles, using the imaging device, at imaging positions of the nozzles. The imaging positions are positions to which the nozzles are allowed to move, respectively, and are positions different from the stop positions.

Abstract: A distributed control system includes a tree topology network or a daisy-chain network including a communication parent station, communication child stations, and a plurality of communication paths among the communication parent station and the communication child stations, in which the communication parent station and the communication child stations include a scheduling unit that controls a transfer cycle that is temporal intervals of data transfer. The scheduling unit sets the transfer cycle that is the fastest out of a plurality of the data as a reference cycle, counts the number of times each time the reference cycle elapses, and imparts a value of the number of times to the reference cycle as a cycle number. When the cycle number reaches an optional number, the number of times is returned to an initial value, which makes one cycle of transfer control, and the transfer control is repeatedly executed. For the timing of the reference cycle at which the data is transferred, the scheduling unit defines a cycle number to which the reference cycle corresponds, on the basis of first information corresponding to the data.
