Hybrid airship-drone farm robot system for crop dusting, planting, fertilizing and other field jobs
First Claim
1. A method of automated farming where one or more hybrid airship-drones, with lift provided both by a container containing a buoyant gas and by one or more propellers powered by one or more electric motors, are used to carry out farming tasks.

Abstract
Modern farming is currently being done by powerful ground equipment or aircraft that weigh several tons and treat uniformly tens of hectares per hour. Automated farming can use small, agile, lightweight, energy-efficient automated robotic equipment that flies to do the same job, even able to farm on a plant-by-plant basis, allowing for new ways of farming. A hybrid airship-drone has both passive lift provided by a gas balloon and active lift provided by propellers. A hybrid airship-drone may be cheaper, more stable in flight, and require less maintenance than other aerial vehicles such as quadrocopters. However, hybrid airship-drones may also be larger in size and have more inertia that needs to be overcome for starting, stopping and turning.

2. The method of claim 2 that includes at least the operations of:
-
accepting from a farmer a service order to carry out a farming task on a field or on plants being farmed, creating and maintaining a map of the field and plants being farmed, using the map to transform the service order into individual assignments for the one or more hybrid airship-drones to perform on all or part of the field or for one or more of the plants being farmed, using a reservoir on at least one hybrid airship-drone to hold farm inputs, monitoring the amount of the farm inputs remaining in the reservoir and automatically refilling the reservoir on the at least one hybrid airship-drone when the reservoir becomes empty, tracking the coordinates of each hybrid airship-drone; using the coordinates to automatically plot individual assignments for the one or more hybrid airship-drones and then directing the one or more hybrid airship-drones to proceed along individual paths to individual points in the field and to perform a farming task beginning at those points, using a toolset on at least one hybrid airship-drone in the fleet to deliver the farm inputs or to perform other farming tasks, monitoring the amount of power remaining on the one or more hybrid airship-drones and automatically providing additional power to each hybrid airship-drone when power becomes too low, controlling traffic as the one or more hybrid airship-drones travel so they avoid colliding with people or other things, and directing the one or more hybrid airship-drones to a home base for automatic parking or storage when no longer needed.

3. An automated farming system that includes at least the following:
-
one or more hybrid airship-drone which is configured to allow refillable reservoirs or toolsets, or both refillable reservoirs and toolsets, to be used, a program which creates and maintains a map of the field and plants being farmed and which allows a farmer to input a service order to perform a farming task, and then using the map transforms that service order into directions for each hybrid airship-drone, a home base for parking or storing the one or more hybrid airship-drones when they are not operating, a high-precision positioning unit responsible for tracking the coordinates of the one or more hybrid airship-drones; a control system for simultaneously controlling the one or more hybrid airship-drones, which control system uses the coordinates tracked by the high-precision positioning unit to automatically plot an assignment for each hybrid airship-drone and then directs the hybrid airship-drone to proceed along a path to a point in the field and to perform a farming task beginning at that point, equipment for refilling the one or more hybrid airship-drones with farm inputs, equipment for automatically recharging the one or more hybrid airship-drones with power, and equipment for communicating with the one or more hybrid airship-drones.

4. A system for farming that includes at least the following:
-
at least one hybrid airship-drone capable of moving autonomously or semi-autonomously above a field and plants being farmed and capable of carrying refillable reservoirs or toolsets, or both refillable reservoirs and toolsets, for delivering farm inputs, a control subsystem capable of receiving directions from an operator to carry out farming tasks and capable of simultaneously controlling the at least one hybrid airship-drone to carry out the farming tasks by creating and maintaining a map of the field and plants being farmed, tracking the coordinates of each hybrid airship-drone, using the map and the coordinates to automatically plot an assignment for the at least one hybrid airship-drone, and then directing the at least one hybrid airship-drone to proceed along a path to a point in the field and to perform a farming task beginning at that point, and a power subsystem capable of automatically providing power to the at least one hybrid airship-drone so that they can move and carry out the farming functions.
