Agras

Agras is the product line name used by DJI (Da-Jiang Innovations) for its family of agricultural unmanned aerial vehicles (UAVs). The Agras drones are designed for precision agriculture, enabling controlled application of liquids such as pesticides, herbicides, and fertilizers over fields. They integrate a liquid reservoir, pump-driven spray system, and a flight control platform that allows operators to plan and execute autonomous spraying missions.

Typical features of Agras models include programmable flight paths, swath width control, variable spray rates, and real-time monitoring of flight status. Many models support GPS-based navigation, telemetry links, and optional RTK for higher positioning accuracy. The platform often accommodates modular payloads, with spray systems and nozzles sized to deliver varying volumes per hectare. The MG-1 line was among the earliest widely marketed Agras devices, establishing the general approach to aerial spraying from drones. Later generations, such as the T-series, offer larger payload capacities, improved stability, and enhanced sensors for mapping and field assessment.

Agras drones are used for large-scale and orchard applications, enabling more uniform chemical or nutrient distribution and reducing manual labor and ground-based chemical exposure. Their adoption varies by region and is subject to aviation regulations, environmental considerations, and pesticide-use rules. In addition to spraying, some Agras models support crop monitoring and basic field surveying through integrated imaging systems and compatible software.
