Kray Technologies is developing cargo drones for crop dusting in the Canadian agriculture market. Their solution, Kray Protection, is an automated multirotor drone that can apply crop protection at speeds of 27-37 hectares per hour, at a cost of $1-2 per hectare. This is 20-50 times cheaper than existing aerial application services. The document provides details on the drone design, precision spraying system, market opportunity analysis, competition, and technical specifications. It also outlines the project progress and contact information.

4. 1. Main farmers’ pains
that we’re solving

5. Money & time investment
Application of crop protection impacts up to 70% of yield, defining farmers prosperity.
Thus outsourcing it to aerial or other services leads to limited control and vulnerability.
Too costly
Crop protection with ground application
takes up to 20% of crop value due to
trampling and requires a big equipment
capex.
Aerial application with currently available
aviation services can cut these costs roughly
in half to $25-50 per hectare.
Aerial application in 78% of cases is
outsourced, thus prone to capacity shortage.
Time constraints
The crop protection needs to be applied
in particular moment of the crop or pest
life cycle (often window is limited to 1
day).
So being able to make it exactly when it
is needed is very important and not
possible with current states of things in
any way of application.
Kray Protection UAS is a reliable, inexpensive, in-house, productive aerial
solution for crop protection application that could solve these severe pains,
experienced by any farmer with middle-sized acreage.

6. 2. Our solution
Kray Protection Project Overview

7. Compound multirotor
2m sized UAV
VTOL UAV utilizes central
wing and horizontal thrust
rotor along with lift rotors.
Max speed of
110 km/h
Maintaining low energy
consumption, as lift force is
divided between lift rotors
and wing.
Automated spraying
mission
We use fast stereo vision
solution to create a real-
time surface map and
obstacle avoidance.
Precise GPS navigation
It allows our UAV to follow
crop surface on minimal
altitude of 1 m, avoiding
collisions with ground and
obstacles on the route
automatically.
Coverage speed
27-37 hectares/hour for
chemical application. It
competes with the highest
coverage speeds achievable
with ground robotic & aviation-
base aerial application
solutions. Our solution is
applicable on the field of any
size, on any crop and at any
ground conditions.
Cost of operation
$1-2 per hectare, which is
20-50 times less than
currently available aerial
application services. This
drone replaces aviation
services on fields up to
1000 hectares, being
typically paid back in less
than 1 year.

Protection spraying system
Issues and our innovations

9. The most challenging aspects of aerial
crop protection are:
◍ Reaching maximum yielding capacity
◍ Uniform pesticide application on different
speeds and dosages
◍ Controlled drop application to prevent different
drop sizes
◍ Precision control of dosage in accordance with
application map

10. “Yield capacity in developed
countries is 2 times higher than in
developing countries due to clever
crop protection techniques
application

11. Advanced ultra-low volume spraying
system
Coverage quality
We’ve reached the best
spraying coverage quality on
different speeds of UAV and
application dosages due to
rotary atomizers spraying
design.
This way we simultaneously
change the flow and rotor
spin speed to maintain
stable drop size.
This technique allows us to
uniformly cover all field,
including field borders.
Drop size
Drop size can be adjusted
(30 to 90 micron with
variations of only ±10%).
This allows to use UAV for
insecticides, herbicides and
fungicides application as
well as for foliar dressing.
Pesticide economy
Ultra-low volume
application allows not only
to cover big acreages with
low application cost.
It increases application
efficiency of pesticides up
to 3 times (e.g. for
Roundup) making
substantial economy by
reducing usage of
expensive chemicals.

12. ADVANTAGES OF OUR SPRAYING SOLUTION
◍ Spraying cost decreased by 10 times
◍ Herbicide cost decreased up to 3 times
◍ Maximized yield capacity

13. 4. Market overview

14. “Aerial application drones market of US and
Canada is estimated at $1.8B annually with
formation in next 3 years and occupation in
8 years

15. Our estimation is based on the following
data:
◍ More than 50% of total US&C cropland is operated by farms with
acreage of 50-1000 hectares with median of 310 hectares in Canada
◍ About 90% of farmers use aerial application, paying $25-$50 per
hectare
◍ About 60% of Canadian farmers currently use drones for monitoring
and precision agriculture aerial mapping
◍ About 22% of farmers have their own aircraft for crop protection
◍ Total number of farmers in Canada is about 200K
◍ 1 unit of our drone can cover up to 300 hectares of cropland
◍ In total, about 200 000 drones are required for the middle-acreage
farms of US&C
◍ 6 years is a usual turnover time for light agricultural machinery market
◍ Drone regulation for agricultural market already allows commercial
application in Canada with routine yearly permission from regulator,
and in the US, where FAA certification of solution is needed in addition.

17. 5. Competition

18. Coverage speed
Existing solutions
underperform
compared to Kray
Protection UAV,
covering just 2-7
hectares per hour
Payload
Existing solutions allow
to load only 5-14 litres
of chemicals.
Kray Protection UAV
chemical load is up to
22,5 litres with the
highest payload-to-
weight ratio of 0.8
Applicability
Existing solution are not
fully automated so are not
applicable for big fields
dusting.
Kray Protection UAV
maintains position with the
lowest altitude on high
speed, and avoids
obstacles automatically
Currently there is no professional UAV
solution for crop dusting
Drawbacks of existing solutions:
Existing solutions do not cover middle and big acreage
fields, being appropriate for small households. Due to
high cost of the solutions, payback time can reach up
to several years

19. “Competitor analysis shows that currently
there is no analogies to Kray Protection
solution in the world
