Abstract
A cleaning robot includes a top cover, a bottom cover provided below the top cover, traveling parts provided in the bottom cover, a suction module provided in the bottom cover to suck in foreign materials on the ground, a recessed part firmed to be recessed inward between the top cover and the bottom cover, and a first sensor located in the recessed part.
Claims18
A robot comprising:
- a main body;
- a cover provided on an exterior of the main body;
- a recess provided at the cover, the recess extending across at least one side of the robot, the recess including:
- a first recess recessed inward from a first side of the robot;
- and
- a second recess recessed inward from a second side of the robot;
- and
- a sensor arrangement provided in the recess, the sensor arrangement having a field of view extending across the at least one side of the robot, the sensor arrangement including:
- a first sensor located within the first recess;
- and
- a second sensor located within the second recess,
- wherein a center of a sensing range of the first sensor in a first direction is different from a center of a sensing range of the second sensor in a second direction.
