Abstract: Provided are systems, methods, and computer-program products for generating a personalized item list. In various examples, a server computer on a network can receive a request that includes a user identifier. The computer can use the user identifier to look up a data model associated with the user identifier. The computer can further determine a geolocation, and use the geolocation to determine a list of items associated with an eatery at or near the geolocation. The computer can input the item list into the data model, for the data model to output a probability for each item, the probability indicating a likelihood that the user will select the item. The probabilities can be used to generate a personalized item list, which can be output onto the network for receipt by a computing device.

Abstract: Provided is a light projection system that can be used to indicate a robot's path of travel, a robot including the light projection system, and methods for projecting light to indicate a robot's path of travel. The light projection system can by mounted to the body of the robot, and can be configured to project light onto the ground in front of the robot. The light projection system can be configured to project different illumination patterns that can indicate whether the robot is moving forward, turning, accelerating, and/or slowing down, among other examples.
