Agri Sprayer Drone by Thanos


Significant technological advances have been made in various sectors in India; however, agriculture still lags behind in adopting new technologies. While there are advancements in agri-mechanization, financial products, and supply chain improvements, opportunities for enhancement remain through technologies like Seyna-H10i Agri Dronesand Spraying Drones, proven beneficial elsewhere.

Overcome Farm Labour Shortage

Seyna-H10i, agricultural drones address farm labor shortages by autonomously performing tasks such as seeding, spraying, and monitoring, thereby enhancing productivity and efficiency.

Increase farm efficiency

Spraying with agricultural drones saves time by automating the process, efficiently covering large areas with precision and reducing the need for manual labor.

Save Farming Cost

Employ agricultural drones to reduce farming costs through efficient operations and precise resource management.

Agricultural tasks are challenging, with decreasing manual labor and pesticide risks. Agricultural drones, especially Seyna-H10i, provide a solution by enabling safe and efficient spraying operations, boosting productivity, and reducing risks for farmers.

Spraying Methods

We focused on solving these problems and developed a much-needed product,SYENA – our UAV-based Agricultural Spraying Platform.
Below is a brief comparison of manual vs. UAV-based spraying methods:

At THANOS, we’ve developed Agricultural Spraying Drones in various capacities: 5 Litres, 10 Litres, and 15 Litres. After nearly 3 years of trials, demonstrations, and field operations, we’ve found that 10 Litres (or 10 Kg) is the ideal capacity for Agricultural Spraying Drones. We considered factors such as battery capacity, flight time, ease of transport, and spraying efficiency in arriving at this conclusion. With that introduction, we’d like to present our 10 Litre Agricultural Spraying Drone, SYENA-H10i. You can see it in action over four different crops in the video below:

The SYENA-H10i has successfully covered thousands of acres in spraying pilots and demonstrations over the past 5 years. It has been meticulously optimized for seamless continuous field operations. Below are the documented work rate capacities of the SYENA-H10i

  • 60 acres per day for ultra-low volume spraying (2-3 litres per acre)
  • 30 acres per day for low-volume spraying (8-10 litres per acre)
  • 10 acres per day for medium-volume spraying (25-30 litres per acre)

Please note that these work rates are estimates based on assumed spray volume rates for 5 hours of daily operation. They should not be considered as dosage recommendations for spraying. The correct spray dosage should be confirmed with the agri-chemical manufacturing company or the local distributor before commencing any operations.
