1. A robot cleaner comprising:
a cleaner body including a control unit for controlling autonomous driving;
a sensing unit disposed in an upper edge portion of the cleaner body, the sensing unit being inclined with respect to a side surface and an upper surface of the cleaner body;
an inclined part located on the upper edge portion of the cleaner body, the inclined part being downwardly inclined with respect to the upper surface of the cleaner body;
a bumper disposed to cover at least part of a first half area of the cleaner body including the inclined part of the first half area of the cleaner body, the bumper being configured to be pressed and to absorb impact; and
a front camera located at a front of the cleaner body, the front camera configured to face forward so as to take images toward a front side of the cleaner body,
wherein the sensing unit is located at a position adjacent to a rear area of the bumper and located on the inclined part excluding a portion where the bumper is disposed on the cleaner body,
wherein the sensing unit comprises a first camera part disposed in one side of the upper edge portion of the cleaner body at a first inclination and a second camera part disposed in another side of the upper edge portion of the cleaner body at a second inclination,
wherein the sensing unit is located at a first height from a ground on which the robot cleaner travels, the first height being a height equal to or less than a height at which the highest point of the bumper is located, and
wherein an inclination of the sensing unit is smaller than an inclination of the inclined part.
