Abstract: A tape cleaner is proposed. In the tape cleaner, the structure of the cleaner is simple, weight and volume thereof are minimized, the generation of noise is reduced during use, and the process of replacing an adhesive tape roll is performed rapidly and easily. The tape cleaner includes: an adhesive tape roll on which an adhesive tape is wound; a roll fitting part over which the adhesive tape roll is fitted; a handle part provided at a side of the roll fitting part; a roll-rotation guide part provided on the roll fitting part to guide rotational movement of the adhesive tape roll; and a noise reduction part provided in the roll fitting part to discharge and reduce noise generated during the rotational movement of the adhesive tape roll.

Abstract: A mobile robot to which a shadow removal method and system for surveillance camera-based mobile robot control according to the present invention is applied acquires images from two closely installed surveillance cameras indoors and performs shadow removal at an improved speed compared to the conventional speed, to recognize the obstacle in the image to avoid it and travel. It is anticipated that through the mobile robot using the surveillance camera-based shadow removal method and system of the present invention, the practical use of an intelligent image surveillance system that can automatically analyze images and recognize a dangerous situation to take quick action may be accelerated.

Abstract: A mobile robot employing a method and a system for localizing the mobile robot using external surveillance cameras acquires images from the surveillance cameras installed indoors adjacent to each other, recognizes objects included in the images by removing shadows from the images and performing a homography scheme, and avoids the recognized objects. The mobile robot employing the method and the system for localizing the mobile robot using the external surveillance cameras enables rapider localization and lower price as compared with a conventional image-based autonomous robot, so that the commercialization of a service robot is accelerated.
