1. After Huawei, DJI was sanctioned again: the design software was blocked.
On March 12, it was suddenly reported that DJI had received an email from the design software company Figma. Figma said in the email: "Hello, we learned that DJI was included in the released sanctions list, so Figma can no longer provide you with access to our software. We have started to freeze your account, and you will no longer be able to access your style through Figma, but we will do so later.
Figma, founded on 20 12, is a web-based interface design collaboration tool, which can save the project in the cloud at any time, thus ensuring that multiple users can comment or modify the design in real time. It has three remarkable characteristics: real-time collaboration, vector grid and version history.
2. Long-endurance laser unmanned aerial vehicle for clearing tree obstacles
The invention discloses a long-endurance laser tree obstacle clearing unmanned aerial vehicle issued by the National Patent Office and a using method thereof, belonging to the technical field of unmanned aerial vehicle cleaning devices.
The invention relates to a long-endurance laser tree obstacle clearing unmanned aerial vehicle, which comprises an unmanned aerial vehicle, an obstacle clearing device installed on the unmanned aerial vehicle and a ground remote controller for controlling the unmanned aerial vehicle. The controller is connected with the ground remote controller in communication, and an image recognition algorithm is arranged in the controller, and the image recognition algorithm automatically calculates the distance between the tree and the conductor based on the three-dimensional laser point cloud model of the transmission line tower. The invention can quickly and accurately remove tree obstacles, and avoids the problems of safety, incomplete obstacle removal and the like caused by manual climbing.
3. A new folding rotor tilting quadrotor UAV.
The National Patent Office released a new type of folding rotor tilting quadrotor UAV, which mainly relates to the field of quadrotor UAV manufacturing.
A quadrotor unmanned aerial vehicle with tiltable transition structure comprises a fuselage, a rotor folding module, a tiltable module, a flight control module, a brushless motor and a propeller, wherein the fuselage is connected with the tiltable structure through the rotor folding structure, and the brushless motor and the propeller are installed on the tiltable structure. When the UAV rotor fails, the flight control module can control the inclined rotor propeller relative to the failed rotor to stop and retract the two rotor arms, which reduces the deviation of the center of gravity caused by the uneven force distribution of the failed arms and ensures the stability of the center of gravity of the aircraft.
4. Italy prevents China enterprises from acquiring Italian military UAV enterprises.
According to Reuters 1 1, citing three Italian government sources, the Italian government announced on Thursday that a deal to sell military drones to investors in China was invalid.
It is reported that 75% of the shares of Alpi Aircraft Manufacturing Company in northern Italy were sold to China investors in 20 18. After the investigation of the transaction was initiated last year, the Italian government approved the cancellation of the transaction at the cabinet meeting on Thursday, because they decided that the participants in the transaction failed to notify the Italian government according to the so-called "golden rights" regulations. According to informed officials, in addition to canceling the transaction, the Italian government also imposed fines on the participants of the transaction.
The "golden right" regulation is said to protect assets with strategic significance. Since the implementation of 20 12, the "golden right" law has prevented foreign enterprises from entering Italy six times. It is worth noting that five of these six times were to prevent China enterprises from bidding, and four times occurred after Draghi took office.
5. Ukrainian military drone flew to NATO and crashed in Croatia.
According to the website of Russian Viewpoint 1 1, a Swift UAV that took off from Ukraine crashed in the capital of Croatia at1/local time via Hungary. It is said that two Ukrainian drones flew to Crimea to perform their tasks, but one of them lost contact due to Russian military intervention and flew to NATO countries.
