Setting out tree planting

Construction Staking Drone: Increasing speed of staking out of dense parallel lanes and grids efficiency and improving precision reliability.

I have built a working model and patented a mechanism retrofitted on an agricultural crop dusting drone Agras T16 DJI (example result in bottom attached link), leveraging its existing capabilities of RTK satellite precision flight guidance and millimeter radar for consistent ground clearance, drone was intended for crop dusting in agriculture by OEM. For our problem to solve a timely conventional process after a set-out survey is done, the necessary procedure of transferring the design onto the land is by setting out its exact position in the 'real world,' typically on the minimum point of interest. On a commercial farm, for example, a team of 5 experienced to less experienced will come with a basic dumpy level or theodolite survey equipment (if even) and measuring tape to stake-out plant lines. These references are needed for the tractors or machinery to perform soil preparation operations where extreme precision is necessary and often far-reaching over vast distances and orientations depending on the vector of the sun relative to topography and modern tree or orchard structures. Also adding complexity is that modern farming is moving to more extreme sloped areas. This causes more and more extreme distortion due to human error and a general increase in difficulty dealing with such complexities in the field.

 Traditionally a surveyor will put out a few benchmarks or references across a field and far apart. After a team of manual laborers set out wooden pegs or stakes in between by measuring tape in agricultural norms in intervals of 3.5 meters or 4 meters, for example. This causes many faults to occur, ranging from the error of parallax to human error. This has caused a lot of downtime during the construction process, and the final results being the lines or paths being oblique or not parallel. This also takes a very long time, 5- 10 people 1 hectare per day, and the result on average would be less than ideal. With the drone solution still using the surveyor's benchmark as a calibration point, the field can be mapped with the drone UI, then calibrated on the surveyor's benchmark. Then the drone can be initiated to fly and stencil PVA-based emulsion or colorful markings on the planned path or lines across the planned area with <3mm precision. Using this method, we can do a 1 hectare of the same equivalent in <45min of what traditionally took a day which is >1000% improvement using only one drone operator and one assistant.
