The present invention relates to a robot and method for estimating an orientation on the basis of a vanishing point in a low-luminance image, and the robot for estimating an orientation on the basis of a vanishing point in a low-luminance image according to an embodiment of the present invention includes a camera unit configured to capture an image of at least one of a forward area and an upward area of the robot and an image processor configured to extract line segments from a first image captured by the camera unit by applying histogram equalization and a rolling guidance filter to the first image, calculate a vanishing point on the basis of the line segments, and estimate a global angle of the robot corresponding to the vanishing point.

Disclosed are a mobile robot with a single camera capable of performing a cleaning process with respect to surroundings, and capable of more precisely making a 3D map of the surroundings including a plurality of feature points, and a method for recognizing 3D surroundings of the same. According to the method, images of the surroundings are captured, and a preset number of particles with respect to feature points of a first image are projected to a second image based on matching information of feature points extracted from the two images sequentially captured, thereby extracting 3D information of the surroundings.

A method for controlling a robot cleaner includes: detecting a cleaning target space, setting a cleaning region within the detected cleaning space and cleaning the set cleaning region; if the set cleaning region is completely cleaned, moving to a not-yet-cleaned region adjacent to a cleaning completion spot of the cleaning region; and setting a new cleaning region in the not-yet-cleaned region and performing cleaning. Without repeating a cleaning region in the cleaning target space, the robot cleaner can extend its cleaning region, so the cleaning efficiency of the robot cleaner can be improved. Also, the robot cleaner can be smoothly enter a new cleaning target space or released therefrom. In particular, even when the entrance of the new cleaning target space is narrow, the robot cleaner can smoothly enter the new cleaning target space and gets out thereof.

Detecting apparatus of robot cleaner and controlling method of robot cleaner

Disclosed are a mobile robot and a controlling method thereof. The mobile robot comprises: a case; and a sensor unit having two or more sending portions and two or more receiving portions arranged on an outer surface of the case separately and alternately. The plurality of sending portions and receiving portions are arranged in an alternating manner, thereby having a directivity. Also, since signals received through the receiving portions are judged based on a reference value, an area unallowable to be detected for an obstacle sensing is minimized, which allows an obstacle to be detected more accurately. When the obstacle corresponds to a side wall on the basis of a moving path of the mobile robot, a distance between the side wall and the mobile robot is calculated based on signals received by the receiving portion closest to the side wall. Accordingly, the mobile robot can move with maintaining a constant distance from the side wall.

Mobile robot and controlling method thereof

Provided are a temperature control method and apparatus for driving a polymerize chain reaction (PCR) chip. In the temperature control apparatus, which is for a polymerize chain reaction chip, PCR chips receive electric power from the outside and generating heat to maintain a predetermined temperature and for outputting actual temperature information to the outside. electric power supply units supply electric power to the PCR chips according to input control signals, and a controller generates the control signals based on control information including pre-established control temperature and control time information and the actual temperature information supplied from the PCR chips in order to supply the control signals to the electric power supply units. In the present invention, it is possible to examine various kinds of DNA at the same time because the temperature control apparatus controls the temperatures of DNA samples at the same time.
