Patent number: 9480380Abstract: A cleaning robot having improved traveling performance and a method of controlling the same. The cleaning robot detects a stuck state such as a ‘jammed state’, ‘lifted state’, or ‘object-caught state’ by using a motion instruction or sensor information and quickly escapes from the stuck state caused in various traveling conditions by using a wheel structure capable of changing a total height of the cleaning robot. In addition, a degree of risk and type of the stuck state is predicted before the cleaning robot is in the stuck state so that the cleaning robot may deal with the stuck state in advance. The cleaning robot may escape from the stuck state via rapidly deceleration or quick stopping in accordance with the predicted degree of risk of the stuck state, and the cleaning robot may efficiently deal with the stuck state by using information to select an escaping method suitable for the type of the stuck state.Type: GrantFiled: October 9, 2014Date of Patent: November 1, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jeong Ki Yoo, Sung Jin Park, Jun Young Lee, Dong Min Shin, Dong Hun Lee, Jae Youl Jeong, Shin Kim, Heum Yong Park, In Hak Na

Publication number: 20160259336Abstract: Proposed are a robot cleaner having an improved wheel structure to escape from being stuck in various travel conditions, and a control method thereof. The robot cleaner may smoothly escape from a door sill or an obstacle to stably travel irrespective of a state of a floor by providing an optimal frictional force of the floor through the control of an electric current of a motor when the robot cleaner escapes from being stuck. Also, the robot cleaner may stably travel without shaking by controlling an electric current flowing through the motor after the robot cleaner escapes from being stuck and before the driving wheel returns to a normal mode. Furthermore, it is possible to prevent a wheel mechanism such as a gear from being damaged by an external shock (e.g., which is caused by a pet or an object drop) or a shock caused by autonomous vibration when the robot cleaner crosses over an obstacle.Type: ApplicationFiled: March 1, 2016Publication date: September 8, 2016Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dong Hun LEE, Sung Jin PARK, Heum Yong PARK, Dong-Hyun LEE
