The present invention relates to a lawn mowing robot and, more particularly, to a lawn mowing robot comprising: a body forming the exterior; wheels for moving the body; a blade provided on the bottom surface of the body to perform lawn mowing while the body moves; and an antenna assembly for transmitting and receiving signals to and from a plurality of beacons installed in a work area in which the lawn mowing is performed. The antenna assembly includes: an antenna rod for transmitting and receiving the signals to and from the plurality of beacons; a support part spaced apart from the antenna rod and coupled to the body; an elastic member which connects the antenna rod and the support part and provides a restoring force so that the antenna rod returns to the previously installed position with respect to the support part; and a wire member which connects the antenna rod and the support part and supports the antenna rod so that the distance between the antenna rod and the support part is maintained at a pre-set distance or less.
