First Claim
Patent Images
1. An image-based self-diagnosis apparatus for a mobile robot, comprising:
- a driving unit making a linear move and rotational move;
a camera unit capturing visual images;
a memory unit storing visual images captured by the camera unit; and
a control unit capturing a reference image at a current location through the camera unit, capturing a comparison image after controlling the driving unit to make at least one of linear moves and rotational moves by a preset amount, storing the captured reference and comparison images in the memory unit, and determining the abnormality of the mobile robot by comparing the stored reference image captured before the moves and the comparison image captured after the moves.

Abstract
An image-based self-diagnosis apparatus and method for a robot determines the abnormality of a driving unit of a mobile robot by using a camera and reporting to the user in real time. The image-based self-diagnosis method may include: capturing a reference image at the current location and storing the captured reference image; capturing a comparison image after making at least one of linear moves and rotational moves by a preset amount, and storing the captured comparison image; and determining the abnormality of the mobile robot by comparing the stored reference image and the comparison image with each other.
