Multipurpose underwater robot

Abstract

The invention discloses a multipurpose underwater robot which comprises an underwater navigation body, a communication relay buoy, a master control terminal and master control data transmission equipment. The underwater navigation body comprises an autonomous control operation mode, an optical fiber remote control operation mode and a relay remote control operation mode and is sequentially provided with a bow section, a bow portion propelling section, an electronic cabin section, a tail portion propelling section and a main propelling section. An optical fiber socket and a wireless data transmission antenna are arranged at the outer portion of the electronic cabin section. The optical fiber socket is connected with a debugging optical fiber or a watertight optical fiber or a bearing optical fiber in a matched manner. A battery pack, an attitude sensor, a network switch, an optical transceiver and an autopilot are assembled in a cabin shell of the electronic cabin section. By the adoption of the multipurpose underwater robot, through the matched connection of the debugging optical fiber or the watertight optical fiber or the bearing optical fiber, the three operation modes are provided, the robot can be used as a non-cable underwater robot and can also be used as a cable underwater robot, and the beneficial effects of the cable underwater robot and the beneficial effects of the non-cable underwater robot are achieved in the relay and buoy remote control operation mode.

Description

technical field [0001] The invention relates to the technical equipment field of an underwater robot, in particular to a multipurpose underwater robot, which is mainly suitable for underwater detection, observation, school teaching, demonstration and research and other fields. Background technique [0002] Unmanned underwater vehicle (UUV) can be divided into untethered underwater vehicle (AUV) and cabled underwater vehicle (ROV) according to the different connection methods with the shore-based control system. [0003] The cableless underwater robot has the advantages of wide range of activities and no need to support the mother ship to follow. However, due to the lack of communication cable connection between it and the main control terminal, the data transmission with the main control terminal is mainly through wireless data transmission equipment and underwater acoustic communication equipment.

Problems solved by technology

[0003] The cableless underwater robot has the advantages of wide range of activities and no need to support the mother ship to follow. However, due to the lack of communication cable connection between it and the main control terminal, the data transmission with the main control terminal is mainly through wireless data transmission equipment and underwater acoustic communication equipment. Or the method of downloading and reading after salvage and recovery has the disadvantages of not being able to transmit data in real time and the amount of data transmission is strictly limited.

[0004] The cabled underwater vehicle (ROV) is connected to the main control terminal through the umbilical cable, supplies power to the underwater robot through the umbilical cable, and realizes information communication, which effectively overcomes the disadvantage that the cableless underwater robot cannot communicate with the main control terminal in real time, Due to the limitation of the umbilical cable, the cabled underwater robot has the disadvantages of limited range of motion and the need to support the mother ship to follow, especially when performing some special tasks to support the mother ship is difficult to follow, which greatly limits the scope of use of the cabled robot

[0005] Both cableless robots and cabled robots have their own advantages in actual use, but are also limited by some unfavorable factors, which limit their range of use to varying degrees.
