Abstract: A diagnostic device for diagnosing distribution of a radical in a plasma processing chamber, the diagnostic device, may include a spectrometer receiving an optical signal through at least one optical channel connected to the plasma processing chamber, and performing spectral analysis on the optical signal in response to a synchronization signal corresponding to each of states of a multi-level pulse applied to the plasma processing chamber and a synchronizer generating the synchronization signal corresponding to each of the states of the multi-level pulse.

Abstract: A moving robot may include a first location recognition module configured to extract a straight line in a driving process and recognize a location using the extracted straight line and a second location recognition module configured to confirm the recognized location by reflecting the location recognized by the first location recognition module based on the image information obtained from the surroundings by way of an image capturing device.

Abstract: A robot cleaner and a method for controlling a robot cleaner are provided. The robot cleaner may include a casing, a drive disposed in the casing, a camera disposed in the casing to acquire an image of a user's gesture, and a controller that extracts an image including a user's arm image from the image acquired by the camera to determine an angle and a direction of the arm expressed by the user's gesture from the arm image and determine an intension expressed by the determined arm angle, and controls the drive based on the determined intension.
