Robotic ordering and delivery system software and methods
Systems, methods and devices for the automated delivery of goods form one to another using a robotic tug and accompanying cart. A computer within the tug or cart stores an electronic map of the building floor plan and intended paths for the tug to take when traversing from one location to the next. During the delivery, a variety of different sensors and scanners gather data that is used to avoid obstacles and/or adjust the movement of the tug in order to more closely follow the intended path. The system preferably includes both wired and wireless networks that allow one or more tugs to communicate with a tug base station, a primary network located at the site of the delivery and a remote host center that monitors the status and data collected by the tugs.
