Patent number: 10248125Abstract: Disclosed herein are a cleaning robot in which light emitting portions emitting infrared rays are installed to face forward, sideward, and upward and infrared rays which are reflected by obstacles and return are received by one light receiving module to sense obstacles to prevent an increase in manufacturing cost caused by installing a plurality of light receiving portions and simultaneously to sense obstacles located above and a method of controlling the cleaning robot. The cleaning robot including a body and a driving portion which moves the body includes at least one light emitting portion which emits light to an obstacle, a light receiving module which obtains an image signal of the obstacle by receiving the light reflected by the obstacle, and a control portion which generates obstacle sensing information based on a position of the image signal obtained by the light receiving module and controls the driving portion based on the generated obstacle sensing information.Type: GrantFiled: April 15, 2016Date of Patent: April 2, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Chin Woo Kang, Kyong Su Kim, Jong Seok Park, Suk Hoon Song, Kyu Ha Lee

Patent number: 10048682Abstract: A mobile robot system for allowing a user to easily input a control command of a mobile robot, and a remote control method for the same are disclosed. The mobile robot system and the remote control method thereof can allow a user to easily input control commands regarding the movement and operation of the mobile robot using the jog-dial interface, such that the possibility of causing input errors can be reduced and desired commands can be quickly and efficiently transmitted, resulting in increased user manipulation of the mobile robot system. When the user enters the rotation command of the mobile robot, the mobile robot system can allow the user to perform intuitive interfacing through shuttle manipulation, such that the mobile robot system can facilitate transmission of a movement command having a circular trajectory and the same mobile robot control as in the user-intended control is achieved, resulting in implementation of emotional interface capable of increasing user accessibility.Type: GrantFiled: April 18, 2016Date of Patent: August 14, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hwan Chang, Hong Jun Kim, Hee Suk Yoon, Ki Yong Lee, Chin Woo Kang, Kyong Su Kim
