Description

technical field [0001] An unmanned aerial device with single-axis dual rotors, a system with the device, and a remote control method. Background technique [0002] The history of the development of the Unmanned Aerial Vehicle is from the balloon type in 1783. After the baptism of the World War and the Industrial Revolution, the pilots who operate the aircraft are gradually removed. For military training purposes, an unmanned target drone is created, which is now used in the military. The application of UAVs is extended to remote control to carry out third-place strikes. Today's drone applications are no longer just for military purposes, but more for other purposes such as leisure and entertainment or logistics. Combining technological equipment and machine learning, they are respectively used in aerial photography, carrying objects, extended signals and environmental detection. In addition to the development of integrated circuits, the size of the chip is reduced and the f...

Problems solved by technology

[0003] As far as devices are concerned, technological progress has created many derivative applications of drones, but there are still the same limitations and application difficulties in quadcopters or single-axis drones. First, when using drones for aerial photography, then For multi-axis or single-axis aircraft, the camera equipment is mostly installed under the fuselage, but the fuselage is usually surrounded by propellers and fuselage extension arms, so that when the movement offset is large and the elevation angle of a specific azimuth must be increased or decreased sharply, It is easy to take the aforementioned propeller and extension arm into the picture, resulting in occlusion in the result of the aerial photography, causing troubles in subsequent productions; secondly, to solve the aforementioned occlusion problem, the camera is often extended with the gimbal to increase the distance of the fuselage as a response. However, it also increases the weight of the fuselage itself, which greatly reduces the battery life; the third is to pursue high image quality and imaging precision, and the configuration of the camera lens often requires replacement needs and considerations. This is different from the mechanical structure of a single-axis drone. It is also necessary to consider the weight change of the camera set on the single-axis drone, so that the single-axis drone will undoubtedly increase the complexity of the mechanical structure of the single-axis drone in order to achieve stable flight, and increase the difficulty of manufacturing the single-axis drone. , increasing the cost of manufacturing

[0004] To undertake the mechanical structure of the single-axis drone mentioned above, especially when moving horizontally, in order to change the offset, whether it is the tilter (Swashplate) to tilt the rotor cone to a specific azimuth angle, let the single-axis drone Moving in a specific orientation, or tilting the rotor cone by changing the counterweight of the horizontal plane, as a solution for the movement of a single-axis UAV, will face a complex mechanical structure of the tilter, or it is difficult to accurately control the amount of counterweight change. In addition to increasing the weight, it also increases the difficulty of manufacturing and operation; in order to achieve precise control, its structure must be more complicated, and the complex structure brings more difficulties in manufacturing and increases the overall production cost.

[0005] So far, most of the people who control drones are still professional remote control aircraft players. Due to the limitation of the structural complexity of three-axis or four-axis aircraft, the current drone control is more difficult than the previous control method of remote control aircraft. much more complicated

Even users who are accustomed to remote control aircraft in the past may not be able to control the drone smoothly, not to mention that it is even more difficult for inexperienced new users to get started easily

In particular, the control of three-axis or four-axis unmanned aerial vehicles is not an intuitive control mode. In addition, the feedback from the remote control is easy to make the control deviation, which undoubtedly increases the threshold for the control of the drone, not to mention the fact that the process itself is difficult. Complicated flight routes and angles to achieve desired operational goals

[0006] On the other hand, today's drones transmit images to the screen of the remote control device through radio frequency technology, or use other communication devices that can be connected to the drone, such as mobile phones or tablet computers, for real-time image transmission. This is an attempt to make the operation process more intuitive and humanized, but this control mode is only a replacement for the original remote control device. It is just a transfer of the traditional control interface to a mobile communication device, but it is not a control solution that conforms to human intuition.
