Systems and Methods for Mixed-Use Delivery of People and Packages using Autonomous Vehicles and Machines

Abstract

People and packages are delivered to and picked up from delivery locations by autonomous vehicles that also carry autonomous robots. When a package needs to be picked up or delivered at a particular location, an autonomous robot is deployed from the delivery vehicle and takes the package to the doorstep or other predetermined location or picks up the package from that location and brings it back to the delivery vehicle. After this pickup or delivery, the autonomous robot stows itself back in the delivery vehicle.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of example embodiments. It will be evident to one skilled in the art, however, that embodiments can be practiced without these specific details. In some instances, well-known methods or components have not been described in detail so that the details of the present invention are not obfuscated.

[0022] In the interest of clarity, some routine features of the implementations described herein are omitted. It will be appreciated that in the development of any actual implementation of the present invention, certain decisions must be made in order to achieve specific goals, and that different decisions may be made to achieve different goals without departing from the teachings of the invention. While certain implementations might be complex and time-consuming, they would nevertheless be routine to accomplish for those of ordinary skill in the art having the benefit of this disclosure.

[0023] The invention set forth herein is intended primarily for use with pickup and delivery of people and packages within the radius of an autonomous delivery vehicle, and in particular, the radius an autonomous delivery vehicle can travel in a given 4 or 8-hour period. In certain embodiments, the present invention addresses the pick-up and delivery of people and packages within a defined area, such as an area less than 100 square miles or an area less than 50 square miles. It is expected that the present invention will be tailored to use in an urban or suburban setting, although other settings are possible where efficiencies can be realized.

[0024] In embodiments, the inventive method set forth herein employs a driverless delivery vehicle capable of carrying both passengers and packages, such as a Ford Transit Connect Van modified for full autonomy, or similar vehicle. Currently, there are a large number of third party organizations and companies that are developing vehicles capable of autonomous navigation and operation (“driverless vehicles”), such as Uber ATG, Argo AI, Waymo and others. The present invention is intended to be agnostic with regard to the particular driverless system that is employed, so long as the system has a memory that can save a route for the delivery of packages and can readily re-calculate that route in order to efficiently address changes that may occur during a delivery run.

[0025] Certain embodiments of this invention specifically lay out methods and example embodiments for simultaneous mixed-use people-carrying (as in a taxi service) and package delivery. In some embodiments no modification of a standard autonomous vehicle is required, while other embodiments may require extremely minor modification to house a deployment mechanism for a separate “curb to doorstep” delivery vehicle or robot. Embodiments may carry people and packages at the same time, with an on-board “curb to doorstep” autonomous robot, that can deliver packages to a doorstep, mounted in the rear of the vehicle with an automatic door gate. Alternatively, the robot may be mounted in a location adjacent to the side door of the vehicle depending on the specific application, such as for delivery of mail or packages to a mailbox. In still other embodiments, there may be a specialized vehicle designed specifically with a package and robot bay separate from seating for people.

[0026] In FIG. 1, an overall process 10 for delivery of a group of packages or people in accordance with certain embodiments of the present invention is described. In embodiments, at the start of a work shift, an autonomous delivery vehicle is loaded with one or more packages, one or more passengers or both. In certain embodiments, this loading occurs at a distribution center or sorting facility. Alternatively, it could occur at an airport or train station. In other embodiments the work shift could begin with a pickup at a residence or workplace. At the time of the pickup or, alternatively, when the request for a pickup has been made, a route calculation system calculates an optimized delivery route for all people or packages to be delivered or picked up 15. Once this has been calculated, the delivery vehicle begins to navigate to the first calculated location 20. In some embodiments, the route calculation will be re-calculated on a continual basis, such as every thirty seconds, to account not only for new stops, but also for changes in traffic conditions or road work. As will be apparent to those of skill in the art, existing third party GPS-enabled navigation software such as Waze or Google Maps can be leveraged to assist with generating the delivery route. Waze is registered trademark of Google LLC of Mountainview, Calif.

[0027] At any point during the work period, including prior to the delivery vehicle reaching the first location, a new request for pickup and/or delivery can be received by the route calculation system 25. If such a request is received and the route calculation system determines the new delivery stop can be efficiently incorporated into the existing route structure 30, the route will be updated accordingly and the delivery vehicle will navigate to an address associated with the new destination when it is most efficient and proceed as previously described. Alternatively, the route calculation system can be biased to prioritize the pickup and delivery of human passengers over packages in order to minimize travel time for human passengers. Similarly, packages or items that are temperature-sensitive, such as groceries, can also be prioritized.

[0028] In the event that no new request is made prior to arrival at the first destination, or in the event it is determined that any such request would not be efficiently incorporated into the existing route, the delivery vehicle proceeds to the address of the original destination for delivery or pick-up 35. If the delivery or pick-up happens to be a package, an autonomous robot is deployed from the delivery vehicle to carry or retrieve the package between the delivery vehicle and the doorstep or other destination as more fully explained with relation to FIG. 2. In certain embodiments, the robot is bipedal and autonomous, with an option for remote teleoperation by a human to handle situations that may be confusing for the robot autonomy. Where the delivery or pickup is of a human being, the delivery vehicle proceeds to the address associated with the pickup or delivery and awaits a signal to proceed, such as via an app or through the use of an on-board vehicle sensor that can determine when a person has entered or exited the vehicle.

[0029] After the delivery or pickup is complete 35, a determination is made whether there are additional stops to be made, the vehicle repeats the process discussed 40. If, however, no additional deliveries or pickups are planned, the delivery vehicle travels to an idling location 45, either predetermined or calculated based on current location, until a new delivery request is made 25 or the shift ends. The goal for such a system, however, is the maximum utilization of the fleet infrastructure and 100% service time for the robots and vehicles.

[0030] FIG. 2 sets forth an embodiment of a delivery or pickup system and method 100 for packages once the delivery vehicle arrives at the curb 110 having an address and being in front of a destination location in accordance with certain embodiments of the invention. FIG. 3 illustrates a delivery vehicle 200 in accordance with certain embodiments of the present invention. If a package is being picked up or delivered, a door 210 of the delivery vehicle, such as a lift gate in the back of the vehicle 200, is opened to enable egress by an autonomous robot 220. Prior to exiting the vehicle 200, the robot 220 accesses available information about the local surroundings. In certain embodiments, the robot 220 accesses information about the destination including, for example, the address, a picture of the home or office from the street, a previously obtained map of the property, the weather, recipient-submitted information, telemetric or other data collected by the delivery vehicle 200, or other relevant information 120. This information may be provided to the robot 220 via an external data provider or by an electronic control system installed in the delivery vehicle. In certain embodiments, the external data provider is a remote data storage center the robot 220 accesses via a wireless data link.

[0031] Next, the robot 220 deploys 130 from the delivery vehicle 200 and retrieves the appropriate package 230 and either carries it to the doorstep of the home or office for delivery or retrieves a package from the doorstep or other predetermined location if the stop is for the purpose of picking up a package. In an alternative embodiment, the robot 220 loads itself with a package 230 prior to deployment. Once the pickup or delivery is complete, the robot reboards the delivery vehicle 200 and the vehicle 200 continues to the next stop. In some embodiments, the vehicle may re-charge the robot when it is on-board, to reduce the required battery life of the robot to only that required to do a single delivery, rather than requiring sufficient charge to operate the robot all day. In embodiments, people who opt for autonomous delivery or pickup will grant permission for the robot to come onto their property and will likely need to generate a detailed map of their yards in advance to assist with delivery.

[0032] With reference to FIG. 4, in certain embodiments, the robot 220 is a bi-pedal autonomous robot having legs 410 that enable it to move from place to place in a manner that could be referred to as “walking.” The robot 220 further has arms 420 that can be employed to carry the packages 230 referred to above to and from the delivery vehicle 200. The robot 220 can autonomously operate through use of a multitude of on-board sensors, control circuits, motors and springs wherein it can balance both holding and not holding a package and can employ its sensors to avoid obstacles in its path as well as using stored location and mapping data to assist with navigation to and from the vehicle 200.

[0033] In embodiments, the robot 220 is configured to be transitionable between a stowed configuration as illustrated in FIG. 3, and an operational configuration as illustrated in FIG. 4. When the robot 220 is walking and carrying packages to and from the delivery vehicle 200, it is in operational configuration, but its arms 420 and legs 410 can be folded and positioned to transition to the stowed configuration where it is placed on, or connected to, a deployment mechanism 310 mounted inside the delivery vehicle 200. In embodiments, the deployment mechanism 310 may be permanently installed in the vehicle or may be removable. An embodiment of the deployment mechanism 310 is illustrated in FIG. 5.

[0034] In still other embodiments, there may be more than one deployment mechanism 310 and more than one robot 220 deployed from a vehicle 200 at the same time, allowing the vehicle 200 to drop off several robots 220 with brief stops, allow them time to make their deliveries, and pick them up again. The vehicle 200 may pause only momentarily to allow a robot 220 to exit the vehicle 200 with a package 230, to avoid blocking traffic. This problem is especially significant in urban areas, where delivery vehicles often are cited for parking infractions, as they have little other choice but to illegally park while making a delivery.

[0035] While the robot 220 is in stowed configuration, the arms 420 can be used to perform tasks that do not require the use of the legs 410. In embodiments, the arms 420 can extend out of the side of the vehicle 200 to place mail or packages in a mailbox or other receptacle without the robot 220 exiting the vehicle 200. In some embodiments, the deployment mechanism 310 used to hold the robot 220 may be actuated to extend the reach of the workspace by moving the stowed robot 220 in a direction that makes accessing an exterior location easier.

[0036] Certain aspects of the embodiments include process steps and instructions described herein in the form of an algorithm. It should be noted that the process steps and instructions of the embodiments could be embodied in software, firmware or hardware, and when embodied in software, could be downloaded to reside on and be operated from different platforms used by a variety of operating systems. The embodiments can also be in a computer program product which can be executed on a computing system.

[0037] The embodiments also relate to an apparatus for performing the operations herein. This apparatus may be specially constructed for the purposes, e.g., a specific computer, or it may comprise a general-purpose computer selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, the memory/storage can be transitory or non-transitory. Memory can include any of the above and/or other devices that can store information/data/programs.

[0038] In specific embodiments, the methods of delivering people and packages using the vehicles and robots discussed herein are accomplished at least through the use of an electronic control system in the delivery vehicle. In certain embodiments, the electronic control system is comprised of a delivery server having a memory storage module, a processing module, and a communication network to enable communication with and to control certain aspects of the operation of the vehicle and, in embodiments, the deployment mechanism. Some examples of such communication include opening the liftgate on the back of the vehicle to deploy the robot, determining the delivery route, and communicating with the robot for purposes of exchanging data and providing prompts over the communications network that can be wired or wireless. In certain embodiments, the data exchanged between the vehicle and the robot includes the delivery location at the address, identification information about the package or packages to be delivered to a particular address, any data collected by sensors on the vehicle regarding obstacles that may be on the ground between the vehicle and the delivery destination, and any other information or data that may be relevant to delivering the package or packages to the doorstep or to some other predetermined destination. In certain embodiments, the delivery server also communicates with the deployment mechanism for purposes of deploying and retrieving the robot.

[0039] While much of this application has been directed to the use of the robot for residential or office deliveries, the process of loading the van at the beginning of a work shift can be accomplished using the autonomous robot described herein. The robot, armed with a lookup table and a scanner, for example, can “pick” marked packages from shelves and place them in the van for delivery.

[0040] While various illustrative embodiments incorporating the principles of the present teachings have been disclosed, the present teachings are not limited to the disclosed embodiments. Instead, this application is intended to cover any variations, uses, or adaptations of the present teachings and use its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which these teachings pertain.
