Abstract

An unmanned delivery system 100 includes a self-propelled robot 2 , an unmanned aerial vehicle 1 which transports a package to an intermediate location on the way of delivering the package, and a robot controller which controls the self-propelled robot 2 so that the self-propelled robot 2 delivers to a receiver's address 4 the package which is unloaded at the intermediate location.

Claims (27)

1. An unmanned delivery system comprising:

a self-propelled robot;

an unmanned aerial vehicle that transports a package to an intermediate location on the way of delivering the package; and

robot circuitry that controls the self-propelled robot so that the self-propelled robot delivers to a receiver's address the package that is unloaded from a storage of the unmanned aerial vehicle at the intermediate location, wherein

when the self-propelled robot is loaded in the storage of the unmanned aerial vehicle, the robot circuitry controls the self-propelled robot so that the self-propelled robot (i) takes a given storing posture, (ii) charges a secondary battery of the self-propelled robot using power from the unmanned aerial vehicle, and (iii) fixes the self-propelled robot to the storage after charging the secondary battery.

2. The unmanned delivery system of claim 1 , wherein the robot circuitry controls the self-propelled robot, selectively by one of an autonomous operation and a remote operation.

3. The unmanned delivery system of claim 1 , wherein the self-propelled robot includes a plurality of self-propelled robots, the unmanned delivery system comprising a robot interface that remotely operates the self-propelled robots, and

wherein the self-propelled robots and the robot interface are configured so that the self-propelled robots are operable by a sole robot interface.

4. The unmanned delivery system of claim 1 , wherein the unmanned aerial vehicle includes a hoist that lowers a loaded object onto the ground and loads an object on the ground, and

wherein the robot circuitry fixes the self-propelled robot to the hoist, and confirms that the self-propelled robot is fixed to the hoist.

5. The unmanned delivery system of claim 1 , wherein the self-propelled robot includes three assembly units which are a robotic arm unit, a base unit, and a movable unit that moves the self-propelled robot, and

wherein the robotic arm unit is attached to an upper surface of the base unit, and the movable unit is attached to a side surface of the base unit.

6. The unmanned delivery system of claim 5 , wherein a first robotic arm unit that includes a torso part extending perpendicular to the upper surface of the base unit, and a second robotic arm unit that is attached directly to the upper surface of the base unit and is extendable near and along the upper surface of the base unit are selectively attachable to the upper surface of the base unit, and

wherein a traveller that propels the self-propelled robot, and a leg that causes the self-propelled robot to walk at heights are selectively attachable to the side surface of the base unit.

7. An unmanned delivery system comprising:

a self-propelled robot;

an unmanned aerial vehicle that transports a package and the self-propelled robot to an intermediate location on the way of delivering the package; and

robot circuitry that controls the self-propelled robot so that the self-propelled robot delivers to a receiver's address the package that is unloaded from a storage of the unmanned aerial vehicle at the intermediate location, wherein

when the self-propelled robot is loaded in the storage of the unmanned aerial vehicle, the robot circuitry controls the self-propelled robot so that the self-propelled robot (i) takes a given storing posture, (ii) charges a secondary battery of the self-propelled robot using power from the unmanned aerial vehicle, and (iii) fixes the self-propelled robot to the storage after charging the secondary battery.

8. An unmanned delivery method comprising the steps of:

transporting, by an unmanned aerial vehicle, a package to an intermediate location on the way of delivering the package; and

delivering to a receiver's address, by the self-propelled robot, the package that is unloaded from a storage of the unmanned aerial vehicle at the intermediate location, wherein

when the self-propelled robot is loaded in the storage of the unmanned aerial vehicle, the self-propelled robot is controlled so that the self-propelled robot (i) takes a given storing posture, (ii) charges a secondary battery of the self-propelled robot using power from the unmanned aerial vehicle, and (iii) fixes the self-propelled robot to the storage after charging the secondary battery.

9. An unmanned delivery method comprising the steps of:

transporting, by an unmanned aerial vehicle, a package and a self-propelled robot to an intermediate location on the way of delivering the package; and

delivering to a receiver's address, by the self-propelled robot, the package that is unloaded from a storage of the unmanned aerial vehicle at the intermediate location, wherein

when the self-propelled robot is loaded in the storage of the unmanned aerial vehicle, the self-propelled robot is controlled so that the self-propelled robot (i) takes a given storing posture, (ii) charges a secondary battery of the self-propelled robot using power from the unmanned aerial vehicle, and (iii) fixes the self-propelled robot to the storage after charging the secondary battery.
