Unmanned surface vehicle deployment and retrieval system coordinated by unmanned aerial vehicle with parallel extension arms

Abstract

The invention discloses an unmanned surface vehicle deployment and retrieval system coordinated by an unmanned aerial vehicle with parallel extension arms. The system comprises an unmanned aerial vehicle, rhombic extension frames, steering engines and mechanical hooks; two rhombic extension frames are connected to the bottom of the unmanned aerial vehicle, and form parallel extension arm structures; the steering engines and the mechanical hanging hooks are arranged at the bottoms of the rhombic extension frames; the steering engines are used for driving up-down extension and left-right translation of the rhombic extension frames; and the mechanical hanging hooks are used for hooking rectangular frames with guide ropes on an unmanned surface vehicle. The unmanned surface vehicle deploymentand retrieval system coordinated by the unmanned aerial vehicle with the parallel extension arms can precisely control the mechanical extension arms through the unmanned aerial vehicle to realize assistance of the retrieval operation of the unmanned surface vehicle through taking-back of the guide ropes to a mother ship, and has the characteristics of convenient operation, quick movement, capability of recycling and high safety.

Description

technical field [0001] The invention relates to the technical field of robotic arms equipped with drones, in particular to a drone-coordinated deployment and recovery system for unmanned boats with parallel extension arms. Background technique [0002] At present, domestic and foreign deployment and recovery equipment and methods for unmanned boats mainly adopt some relatively traditional deployment and recovery methods. On the mother ship, slide the heavy hammer to the bell mouth along the guide rope to complete the docking with the unmanned boat. However, due to the influence of sea conditions, the high-pressure gas cylinder often leaks air, which makes the guide wire unable to eject to the mother ship, and the high-pressure gas cylinder can only fire two rounds at a time, which is inconvenient to use. [0003] Utilizing the good mobility and operability of the UAV, the parallel extension arm can be mounted under the UAV, and the mechanical hook of the parallel extension ...

Problems solved by technology

However, the range of use of the robotic arm is limited and it cannot perform many different tasks

[0008] 2) The publication number is CN105014687A, and the patent title is "a mechanical arm with a multi-rotor drone". In the patent document, the mechanical arm is connected under the multi-rotor drone. It is composed of a holder, which solves the problem that the robotic arm cannot freely operate at high altitude, but the operability of the robotic arm is not strong, and it cannot realize telescopic movement at any angle

However, the stability of the robotic arm is not good, and the grip is not firm enough
