  • MOBILE ROBOT
    Publication number: 20240269869
    Abstract: A mobile robot includes a driver configured to provide a traveling function, a body disposed at an upper side of the driver, a concave portion recessed inward from a surface of the body, a vent hole formed at an upper side of the concave portion, and a guide inclined surface formed at a lower side of the concave portion. During traveling of the mobile robot, the mobile robot induces inflow of air so that the body can be cooled.
