Abstract
From the background information supplied by the inventors, news correspondents obtained the followingquote: “Delivery robots may be used for purposes such as performing last-mile deliveries of packages alonga delivery route. Such robots may be semi-autonomous or autonomous and may traverse sidewalks andpublic roadways. To increase visibility of a delivery robot to nearby drivers and/or pedestrians, a mastmay be provided on the robot that extends vertically from the base of the robot. The mast may alsoinclude one or more lighting elements that may emit various colors and/or light patterns to communicateinformation to the nearby drivers and/or pedestrians. For example, the lighting elements may provide suchilluminations to indicate an intended motion of the robot to the drivers and/or pedestrians. However, inorder to provide proper visibility to the drivers and/or pedestrians, the mast may need to be constructed tobe above a certain height. Given that the mast may be relatively tall compared to the base of the robot,the mast may produce a large moment arm, which may result in the mast being more likely to break offfrom the robot.”
