Abstract
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.
