First Claim
Patent Images
1. A robot system comprising:
- a planar sign provided along a predetermined running path, the planar sign having a diffusive reflection face for diffusive reflection of light for detection and mirror surface finished portions for mirror reflection of the light for detection, the mirror surface finished portions being respectively provided on both sides of the diffusive reflection face;
a robot having a running subsystem;
a distance direction sensor provided to the robot and configured to sense light diffusively reflected by the diffusive reflection face of the planar sign to detect a distance between the distance direction sensor and the planar sign and a direction from the robot to the planar sign; and
a controller configured to control the robot and comprising;
a map data memory configured to store map data of the predetermined running path including a position of the planar sign; and
a progress direction determining device configured to compare a detection result of the distance direction sensor and the stored map data so as to determine a progress direction of the robot.

Abstract
A robot system includes a planar sign, a robot, a distance direction sensor, and a controller. The controller is configured to control the robot and includes a map data memory and a progress direction determining device. The map data memory is configured to store map data of a predetermined running path including a position of the planar sign. The progress direction determining device is configured to compare a detection result of the distance direction sensor and the stored map data so as to determine a progress direction of the robot.

4. A robot system comprising:
-
a robot having a running subsystem; a camera configured to capture a real-time image; a controller having a memory configured to store a plurality of instruction images obtained as targets of the real-time image at each of a plurality of discrete instruction points provided on a predetermined running path; the controller being configured to obtain an offset value with respect to the predetermined running path, and to control the running subsystem based on the comparison result between the real-time image and the instruction image, and based on the obtained offset value; and the predetermined running path including a normal running range and an offset running range, the controller being configured to control the robot to autonomously run along the predetermined running path in the normal running range, the controller being configured to control the robot to autonomously run along an offset path offset from the predetermined running path based on the offset value in the offset running range, a distance between the instruction points in the offset running range being smaller than a distance between the instruction points in the normal running range. - View Dependent Claims (5, 6)
