DJI agras series: a new era in autonomous agricultural robotics

The technological trajectory of aerial application systems has accelerated dramatically, culminating in the DJI Agras models unveiled at the end of 2025. The introduction of the T25P, T70P, and T100 represents a paradigm shift from simple remote-controlled flying devices to fully autonomous, multi-functional agricultural robots.

These platforms leverage the established architecture of the previous T-series but introduce significantly enhanced actuation capabilities, sensor fusion, and operational flexibility.

The core engineering philosophy behind these models focuses on consolidating farm operations. Rather than utilizing separate machinery for spraying, granular spreading, and logistics, the new Agras line aims to execute complex agricultural workflows through a single, modular interface.

Professional insight: The shift toward multifunctionality indicates a strategic move to reduce Capital Expenditure (CapEx) for farmers. By consolidating spraying, spreading, and logistical capabilities into a single airframe, operators can maximize equipment utilization rates, contrasting sharply with traditional ground-based machinery that often sits idle outside of specific seasonal windows.

The compact segment: the T25p model

Designed for high maneuverability, the T25P serves as the entry point for site-specific crop management. It features a 20-liter fluid reservoir, optimized for treating fragmented or topographically complex plots. The propulsion system supports a maximum takeoff weight (MTOW) of 53 kilograms.

The liquid application system delivers a baseline flow rate of 16 liters per minute. However, the system architecture allows for a modular upgrade; by integrating two additional CDA (Centrifugal Droplet Atomization) nozzles, the flow rate can be enhanced to 24 liters per minute. The atomizers provide a variable droplet spectrum between 50 and 500 microns, with an effective swath width ranging from 4 to 7 meters.

Critical observation: While the T25P is marketed as “compact,” a 24-liter per minute flow rate on a small frame suggests a high application intensity. This capability is crucial for “spot spraying” in Precision agriculture, allowing for high-dose treatments on specific weed patches without the chemical waste associated with blanket spraying.

Beyond liquid application, the T25P integrates the upgraded Solid System 4.0. This auger-driven mechanism is calibrated for the uniform distribution of low-volume granular inputs. Flight safety relies on Safety System 3.0, utilizing next-generation radar for terrain following, ensuring the drone maintains consistent altitude relative to the canopy even in uneven terrain.

Mid-range versatility: the T70p platform

The T70P addresses the requirements of medium-to-large scale operations, offering a balance between payload capacity and operational agility. This model is equipped with a 70-liter spray tank and supports an MTOW of up to 130 kilograms.

The standard hydraulic configuration provides a flow rate of 30 liters per minute. Similar to the smaller model, this can be scaled up to 40 liters per minute via a four-nozzle CDA setup. The operational flexibility is further enhanced by an adjustable swath width of 4 to 11 meters and droplet size control (50–500 microns), positioning the T70P as a robust solution for broad-acre application.

A distinct feature of the T70P is its logistical capability. Aside from its spreading function which disperses fertilizers or seeds at a rate of 400 kilograms per minute the aircraft is rated to lift external loads of up to 65 kilograms.

Professional insight: The inclusion of a 65kg heavy-lift capability transforms the T70P from a pure applicator into a logistical asset. In remote or difficult-to-access fields, this capability allows for the aerial transport of seed bags, spare parts, or harvested samples, significantly reducing downtime caused by ground-based material handling.

Powered by a propulsion system capable of 20 meters per second flight speeds, the T70P utilizes the Safety System 3.0 to maintain obstacle avoidance protocols even when operating near its maximum payload limits.

Heavy-lift capabilities: the T100 flagship

The T100 stands as the apex of the Unmanned aerial vehicle (UAV) lineup, engineered explicitly for high-volume, industrial-scale agriculture. It boasts a 100-liter fluid capacity and a high-performance pumping system delivering 40 liters per minute. With a maximum takeoff weight of 177 kilograms and a swath width reaching 13 meters, the T100 rivals the work rates of smaller ground-based sprayers.

The granular spreading system features a 150-liter hopper capacity, capable of dispensing 100 kilograms of material per flight cycle. The discharge rate matches the T70P at 400 kilograms per minute.

Critical observation: The T100’s specifications suggest it is designed to replace not just manual labor, but also light tractor operations. The ability to carry 100 kilograms of solid material per flight creates a viable alternative for fertilizer application in wet soil conditions where heavy ground machinery would cause detrimental soil compaction.

The T100 introduces a sophisticated sensor suite for flight safety, combining Lidar based spatial mapping, millimeter-wave radar, and a Penta-Vision camera array.

This sensor fusion creates a high-fidelity 3D model of the environment, representing DJI’s most advanced obstacle detection platform to date. Additionally, its heavy-lift configuration supports cargo transport of up to 100 kilograms, opening new avenues for agricultural logistics.

Operational autonomy and strategic integration

A unifying characteristic across the T25P, T70P, and T100 models is the integration of advanced autonomous flight algorithms. These systems dynamically optimize flight paths, ensuring precise terrain following and automatic obstacle circumvention. The modularity of the airframes allows for rapid reconfiguration between spraying, spreading, and heavy lifting, thereby enhancing the overall equipment efficiency (OEE) of the farm.

The combination of expanded tank capacities, high flow rates, and increased flight velocities allows these platforms to cover significant acreage potentially hundreds of hectares per day in optimal conditions.

Professional insight: The operational segmentation of these models is clear. The T25P targets maximizing mobility; the T70P offers a hybrid solution for diverse seasonal tasks; and the T100 provides volume-heavy performance. However, the reliance on high-speed autonomous operation requires robust data management and connectivity infrastructure on the farm to ensure the “digital twin” of the field matches reality.

By replacing traditional application methods with these sensor-equipped robotic platforms, the Agras series not only reduces labor dependency but also enhances the precision of chemical and nutrient application. This aligns with modern agronomic goals of minimizing environmental impact while optimizing input costs, cementing the role of autonomous aerial systems as critical infrastructure in the future of agriculture.
