 On November 10, 1994, China's first untethered underwater robot was successfully developed. At that time, experts believed that the robot, named "explorer", had reached the advanced level of similar underwater robots in the 1990s in terms of functions and major technical performance indexes.
 
It is reported that "explorer" by the Chinese Academy of Sciences shenyang automation institute, China shipbuilding industry corporation 702 institute, institute of acoustics of the Chinese Academy of Sciences, Harbin Institute of Technology, Shanghai jiao tong university and other units spent four years to develop the successful.
 
Today marks the 22nd anniversary of China's first untethered underwater robot
 
According to experts, underwater robots can be divided into manned underwater robots (HOV) and unmanned underwater robots. Among them, unmanned underwater vehicles are divided into two categories. One is a tethered underwater vehicle, commonly known as a RemoteOperatedVehicle (ROV). The other is an Autonomous Underwater Vehicle (AUV).
 
"Explorer" untethered underwater robot is the first untethered autonomous underwater robot in China. The robot is the national "863 project" one of the focus of the automation deployment model development tasks, water diving depth of 1000 meters, range can be up to 12 miles, but in normal recovery level 4 sea condition, can in the designated area search target and record data and sonar image, target to crash to observe and take photos and videos, and can automatically avoid obstacles, underwater acoustic communication ability, but will need to transmit the data and images to the water monitor console.
 
 
The untethered explorer underwater vehicle has three computers on the surface, namely the master control computer, the positioning computer and the image recovery computer. The main control computer provides the remote control operation interface of the carrier system, the programming interface of the autonomous route and the monitoring interface of the carrier system status, realizing human-machine interaction, and obtaining the GPS global positioning system data to calculate the position of the mother ship, so that the carrier's track in the geographic coordinate system can be depicted in the chart. The image recovery computer processes and restores the compressed television signal sent by the master computer.
 
In retrospect, the development of underwater robots in China began in the 1970s and 1980s. China's first underwater robot, hairen I, was developed by the shenyang institute of automation of the Chinese Academy of Sciences in 1986.
 
At present, China has established a "dragon family" of ocean exploration, represented by jiaolong manned submersible, hailong unmanned and untethered submersible and qianlong I unmanned and untethered submersible.
