Description

Technical Field

[0001] This utility model relates to the field of intelligent unmanned aerial vehicle (UAV) technology, and in particular to a precision operation device for UAVs based on a dexterous hand. Background Technology

[0002] In recent years, with the rapid development of drone technology, its application in fields requiring precise operation, such as power line inspection, emergency rescue, and equipment maintenance, has become increasingly widespread. Drones, with their unique aerial mobility, can reach environments that are difficult for personnel to access or are high-risk to perform tasks, demonstrating significant advantages. However, existing airborne operation devices have exposed many technical bottlenecks and design flaws when dealing with complex and precise operation tasks, which seriously restricts the further expansion of their operational efficiency and application scope.

[0003] Currently, most drone-mounted operational devices are specialized designs for specific scenarios, with limited functionality and poor versatility. For example, authorized patent CN202010755130.1 discloses a drone robotic arm for agricultural harvesting. This device employs a first and second concentrically arranged arc-shaped arm. By driving the relative rotation of these two arms, a linked gripper is formed to create a ball-cage-like grasping structure, integrating a cutting blade to simultaneously complete the grasping and cutting operations of the fruit. While this design has some effectiveness in specific harvesting scenarios, its structure has significant limitations: firstly, its movement relies on the rotation of the arc-shaped arm, essentially providing only a single degree of freedom, leading to… The grasping mechanism suffers from severe lack of flexibility and adaptability, making it difficult to perform delicate operations requiring complex spatial orientation adjustments. Secondly, as a highly specialized harvesting mechanism, it lacks modular design and cannot be quickly replaced with other tools (such as sensors, joysticks, or specialized grippers) to meet task requirements, thus limiting the multi-functional application of the drone. Furthermore, its connection to the drone platform is mostly a fixed design with inconsistent interfaces, making it difficult to easily adapt to different models or brands of drone platforms. When replacing a drone, it is often necessary to redesign, process, and install matching supports, increasing usage costs and maintenance complexity. Therefore, this application is provided to address the above problems. Utility Model Content

The drone power supply battery 13 facilitates the power supply of the drone frame 11, thereby facilitating the power supply of the entire device.
