DJI Agras MG-1

The DJI Agras MG-1 is an octocopter designed for precision variable rate application of liquid pesticides, fertilizers, and herbicides, bringing new levels of efficiency and manageability to agriculture.

The MG-1 ‘s powerful propulsion system allows the aircraft to carry up to 10 kg liquid payloads, including pesticides and fertilizers.The combination of speed and power means that an area of 4,000-6,000 m² can be covered in just 10 minutes, or 40 to 60 times faster than manual spraying operations. The intelligent spraying system automatically adjusts its spray according to the flying speed so that an even spray is always applied. This way, the amount of pesticide or fertilizer is precisely regulated to avoid pollution and economize operations.

Equipment used in plant protection operations is susceptible to dust and corrosion, leading to high maintenance costs and shortened lifespans.To counteract degradation, the MG-1 is designed with a sealed body and an efficient, integrated centrifugal cooling system. As it flies, the surrounding air enters the aircraft body via the front inlet, and a triple filter system keeps dust and debris from entering. The air then passes through each of the aircraft’s arms to the motors, capturing heat from all components and the entire structure before exiting and dissipating. The combination of cooling and filtering increases the expected lifespan of each motor by up to three times.

Spray nozzles can be chosen according to the properties of each liquid to optimize atomization, energy efficiency, and the amount of liquid sprayed. The included nozzles are resistant to wear and can be used for thousands of hours without degradation. In total, the MG-1 has four nozzles, each placed directly below a motor. The downward airflow generated by the propellers accelerates the spray, increasing its reach.

The advanced flight controller integrated with the aircraft instantly and precisely responds to pilot inputs. Choose between three flight modes: Smart mode, Manual Plus mode and Manual mode, according to terrain and the specific requirements of each mission.In Smart mode, the flight can be easily planned with the press of a few buttons, without the need for mapping knowledge or other software, making the MG-1 not only the most efficient but also the most easy to use spraying solution. In Manual Plus Mode, the aircraft performs the same turns at the press of a button as it does automatically under the Smart mode, allowing for planning to be done on the fly for fields of irregular shape. Under Manual mode, the pilot freely navigates the aircraft.

The MG-1 automatically records its current coordinates and remembers its past coordinates as it makes its way across the field. In case an operation is interrupted, for example due to depleted battery or spraying liquid, users can quickly land and resume flight from the last recorded point after changing the battery or refilling its tank.

The MG-1 uses a Y-shaped folding design that allows for installation without the use of any additional tools. Its motor arms fold inward, making the aircraft compact and easy to transport in the trunk of a car. Able to withstand harsh conditions, the MG-1’s airframe is made of light, yet durable high-strength carbon fiber.

By integrating a microwave radar together with the MG-1’s intelligent flight control system, the aircraft can scan the terrain below it in real time to keep a constant, centimeter-accurate height above crops. Spray density is maintained even as the ground rises and drops so that an optimal amount of liquid is applied at all times.

The MG-1’s dedicated remote controller is equipped with a Lightbridge 2 transmission system which enables ultra-low-latency controls. Like the aircraft body, the remote is water and dust resistant. The controller’s special low-energy display panel gives real-time flight information and stays powered on for extended periods of time on a single charge. Together with highly responsive joysticks and convenient function keys, mastering the art of agricultural spraying is easier than ever before.
