    摘要: An apparatus and method for detecting a slip of a robot. According to the apparatus and method, the probability of a slip occurring may be preliminarily determined using a first acceleration obtained from an acceleration sensor and a second acceleration obtained from an encoder. Then, finally the occurrence of a slip may be determined using a change in a driving control signal. Thus, accurate detection of a slip can be realized while preventing incorrect determination of slip occurrence.

    摘要: A system and method extracting a corner point in a space using pixel information obtained from a camera are provided. The corner point extracting system includes a light generation module emitting light in a predetermined form (such as a plane form), an image acquisition module acquiring an image of a reflector reflecting the light emitted from the light generation module, and a control module obtaining distance data between the light generation module and the reflector using the acquired image and extracting a corner point by performing split-merge using a threshold proportional to the distance data. The threshold is a value proportional to the distance data which corresponds to pixel information of the image acquisition module.
