## Abstract

A robot alert system includes a robot server that receives contextualized sensor data from one or more mobile robots and generates alerts to one or more individuals according to a set of configured alert rules. The contextualized sensor data includes location data indicating a location of the mobile robot and sensor data obtained by the mobile robot representing sensed conditions of an environment associated with the location. The robot server accesses staff member data associated with each of a plurality of staff members from a staff member database and accesses a set of stored alert rules specifying alert criteria for triggering the alert. Responsive to determining that the contextualized sensor data meets the alert criteria for s target staff member, the robot server generates and transmits an alert to a client device associated with the target staff member.
