An autonomous mobile robot linkage system () includes a plurality of sign posts (SPto SP) disposed along a travel path (); an autonomous mobile robot () which moves along the travel path () while reading the plurality of sign posts (SPto SP) in order using a camera and performs predetermined operations in order of pre-set operation numbers based on identification numbers read from the sign posts (SPto SP); and a host device () which receives information on the operation number being executed from the autonomous mobile robot () and generates an event on the travel path () based on the operation number.

Autonomous mobile robot linkage system and autonomous mobile robot

This image processing device includes: a detection object including cells having first cells capable of reflecting emitted light and second cells incapable of reflecting the emitted light, the cells being squares or rectangles, the first cells and the second cells being arranged in an a×a or a×b (where a, b=3, 4, 5, 6, . . . ) matrix on a two-dimensional plane; and a detector including: an illuminator emitting light; imagers imaging, by a camera, light reflected from the first cells after the first cells and the second cells constituting the detection object are illuminated with the light emitted from the illuminator; and a calculator obtaining information set on the detection object, based on imaged data items taken by the imagers. Such a configuration can accurately identify a compact marker and measure the distance, and achieve a system inexpensively.

Image processing device, mobile robot control system, and mobile robot control method

A mobile robot includes: a drive unit that changes a moving speed and a travel direction; a detection unit that detects a plurality of detection target objects; and a control unitthat acquires a distance Z and a direction θ to the detection target object unit, calculates a travel direction in which the distance and the direction to the detection target object satisfy a predetermined relationship, and drives and controls the drive unit on the basis of the calculated travel direction. The control unit calculates a distance x in a direction orthogonal to the movement route between the detection target object and a current position of the mobile robot and the direction to the detection target object, calculates a difference δx between the distance x and a certain distance Xref, and executes drive control for the drive unit to cause the difference δx to be 0 (zero).

Mobile robot, mobile robot control system, and mobile robot control method

An image processing device includes: a first scan of first area of an image acquired on the basis of reflective light of light emitted to the outside of a mobile body in first direction; a first determination of whether or not a first condition is satisfied on the basis of result by the first scan; a second scan of second area of the image in second direction different from the first direction in a case in which the first determination determines that the first condition is satisfied; a second determination of whether or not a second condition is satisfied on the basis of result by the second scan; a third scan of third area of the image after the second determination determines that the second condition is satisfied; and a third determination of whether or not predetermined information is included in the third area scanned by the third scan.
