Farm Sprayer Drone by Thanos


Despite significant technological advances in various domains in India, agriculture still lags behind in technology adoption. While agri-mechanization technologies, financial products, and supply chain improvements are being introduced, there remains ample opportunity for further enhancement through the adoption of technologies like Agricultural Drones and Spraying Drones, which have proven beneficial in other countries.

Overcome Farm Labour Shortage

34 million farm labourers left agriculture between 2005 and 2012

Increase farm efficiency

Farm 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

Utilize agricultural drones to save farming costs through efficient operations, precise resource management.

Many agricultural tasks are inherently challenging, compounded by declining manual labor availability and the risks associated with pesticides. Agricultural drones, such as spraying drones, offer a solution by enabling effective and safe spraying operations, enhancing efficiency and minimizing 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-H10. You can see it in action over four different crops in the video below:

The SYENA-H10 Agri-Drone has undergone multiple seasons of trials and covered thousands of acres in spraying pilots and demonstrations over the past 5 years. It has been optimized for continuous field operations. The following are the work rate capacities of the SYENA-H10 Agri-Drone:

  • 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.
