A robot for delivering items within a building or within a prescribed radius of a building are provided. A method comprises receiving a task indicating a non-stationary origin and a destination; identifying a current location of the non-stationary origin by interrogating a remote computer associated with the non-stationary origin for the current location of the non-stationary origin; moving towards the current location of the non-stationary origin; determining that the non-stationary origin has changed location by interrogating the remote computer associated with the non-stationary origin for an updated current location of the non-stationary origin; predicting a next location of the non-stationary origin using an artificial intelligence prediction algorithm; determining that the robot has arrived at the origin; detecting an interaction with the robot that is associated with introducing an item to or removing an item from a storage compartment in the robot; moving towards the destination inside of the building.
