1. DJI announced a number of new patents
On February 11, the State Patent Office announced a new patent from DJI, the route smoothing treatment method, device and control terminal of the unmanned aerial vehicle. This is a kind of unmanned aerial vehicle (10) of the route smoothing processing method, device and control terminal (30), the route smoothing processing method can obtain the initial route of the unmanned aerial vehicle (10) in the operating area (101), to obtain the smoothness adjustment parameters; the smoothness adjustment parameters are determined according to the terrain of the operation area, the state information of the work objects in the operation area, the type of work performed on the work object and the smoothness adjustment operation of the user (20), Adjust the parameters according to the smoothness, smooth the initial route to obtain the target route (103), control the unmanned aerial vehicle (10) according to the target route, perform the operation task on the work object in the work area (104). Instead of directly using the pre-configured fixed smoothing adjustment parameters, it is possible to adapt to the different requirements of the smoothness of the route of the unmanned aerial vehicle (10) in various different situations.
On February 1, the State Patent Office announced a new patent from DJI, a flight control method for unmanned aerial vehicles, unmanned aerial vehicles, electronic equipment and media, the method comprising: obtaining flight information and terrain information of the unmanned aerial vehicle; according to the flight information and the terrain information, determining the vertical speed compensation information of the UAV in the vertical direction; according to the vertical speed compensation information, the UAV is controlled in the vertical direction. The proposed method realizes the compensatory control of the UAV in the vertical direction according to the terrain change in advance, avoids the risk caused by the control lag of the UAV in the vertical direction, improves the ability of the UAV to fly in a complex environment with large terrain fluctuations, expands the operation scenario of the UAV, and improves the safety and efficiency of the UAV operation.
On the same day, a patent for a UAV plant protection device and a UAV airborne spraying device was issued, which includes a UAV and a spraying device set on the UAV, the spraying device includes: water tank, which is set on the fuselage of the UAV; impeller pump, which is set at the bottom of the water tank, for pumping the liquid in the tank; the nozzle, which is set at the end of the drone's arm away from the fuselage; and the fluid line, which is used to connect the pump to the nozzle, The pump is fluidally connected to the nozzle through the fluid line. The impeller pump is set at the bottom of the water tank to reliably pump the liquid in the water tank, and the impeller of the impeller pump is fully stirred to make the liquid mixture and the water fully mixed to improve the uniformity of the liquid liquid. Impeller pumps are relatively smaller in size and lighter in weight, which can reduce the load on drones and reduce the production and manufacturing costs of plant protection equipment.
2. Skydio X2D was selected to participate in the U.S. Army's short-range reconnaissance
According to UST, Skydio has confirmed that its X2D unmanned aerial vehicle system has been selected for the U.S. Army's Short Range Reconnaissance (SRR) recording program. Managed by the Unmanned Aerial Systems (PM UAS) Project Management Office of the Office of Aviation Program Executive, the SRR project aims to equip soldiers with a small, rapidly deployable unmanned aerial system solution for reconnaissance and surveillance activities.
After evaluating proposals from more than 30 small unmanned aerial system SRR vendors and conducting rigorous tests with the Defense Innovation Division on five shortlisted companies, the U.S. Army selected Skydio for final integration based on feedback from soldiers and a design review package designed to assess overall product performance, quality, and production readiness.
The Skydio X2D is designed for military and defense customers to perform reconnaissance, search and rescue, and security patrol missions. Skydio X2D pairs Skydio Autonomy, an AI-driven flight autonomy software, with a foldable, highly portable fuselage that utilizes ultra-strong composites to withstand demanding environments. The X2D features a two-color optical thermal sensor and is equipped with GPS-based night flight and strobe lighting, allowing it to work during the day and at night while providing up to 35 minutes of flight time on a single battery. Designed, assembled, and supported in the U.S., X2D meets NDAA's stringent supply chain security requirements and provides enhanced cybersecurity protections. (Source: Drone Network)
3. The United States develops aircraft interception technology
Recently, the United States has developed a new technology for aircraft interception, which can enable fixed-wing UAVs to take off and land directly and capture UAVs in an instant. This aircraft interception system is called sidearm, this system was developed by the U.S. Department of Defense's Institute of Advanced Conduct, of which the U.S. Air Force Combat Research Institute is also involved in the development of the project, and it is still only used in the military field.
According to relevant experts, the original intention of the development of this aircraft interception technology is to enable the drone to launch or land on a small ship. This unmanned aerial vehicle interception system sidearm is mainly composed of three parts, including crane, slide rail and sliding recycler, and the three parts work together. The interceptor can be placed on trucks or ships without being attached to specific tools.
4. The world's first advanced indoor reconnaissance drone - Rocky
AARDVARK is one of the leading tactical equipment suppliers of the US military, and the manufacturer recently released the "world's first advanced indoor reconnaissance drone - Rocky (LOKI) Mk2". The drone was designed and developed in conjunction with the world's top counter-terrorism forces in many countries, solving all the problems associated with the use of tactics and the need for technology.
LOKI Mk2 performance indicators: equipped with a 150° wide-angle forward 0.0008 lux day/night camera; highly sensitive noise-cancelling microphone; on-board integrated flight stabilization/hover system; front and bottom adjustable night vision recognition light source (IR-LED); "turtle turnover mode" - allows the drone to automatically correct itself in the event of a collision; capable of attaching payloads, sensors and other sensors; rugged, replaceable leaf-shaped body design.
Loki (LOKI) Mk2 performance advantages: no need for GPS, Internet and other network services, no need to download the special flight control software of mobile phones or tablets; supporting dedicated control terminal - GCS, no need for flight training, that is, use it; intelligent flight control system, anti-interference, no signal delay and black screen and other issues; group control - a single GCS terminal can control four aircraft at the same time through the intelligent task distribution system; ergonomic design, can achieve intuitive flight control; advanced vision and night vision capabilities, Perform tasks without light or at night.
