iRobot Corporation is an American technology company that designs and builds consumer robots. It was founded in 1990 by three members of MIT's Artificial Intelligence Lab, who designed robots for space exploration and military defense. The company's products include a range of autonomous home vacuum cleaners (Roomba), floor moppers (Braava), and other autonomous cleaning devices.
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs.
An underwater glider is a type of autonomous underwater vehicle (AUV) that employs variable-buoyancy propulsion instead of traditional propellers or thrusters. It employs variable buoyancy in a similar way to a profiling float, but unlike a float, which can move only up and down, an underwater glider is fitted with hydrofoils that allow it to glide forward while descending through the water. At a certain depth, the glider switches to positive buoyancy to climb back up and forward, and the cycle is then repeated.
Unmanned underwater vehicles (UUV), sometimes known as underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input.
The Seaglider is a deep-diving Autonomous Underwater Vehicle (AUV) designed for missions lasting many months and covering thousands of miles. In military applications the Seaglider is more commonly referred to as an Unmanned Underwater Vehicle (UUV).
The iRobot Transphibian is a man-portable, fin-powered AUV and bottom-crawler that can autonomously insert itself into the water and operate in a very shallow area. The fins enable the robot to navigate with 6 degrees of freedom, even in surge, to avoid obstacles and maneuver in tight spaces. In military operations the robot is more usually referred to as a UUV.
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own.
The Chinese 8A4 class ROUV is a remotely operated underwater vehicle (ROUV) used to perform various underwater tasks, ranging from oil platform service to salvage and rescue missions. The 8A4 is a member of a series of related ROUVs developed by the Shenyang Institute of Automation (SIA) in the People's Republic of China (PRC). The predecessor to the 8A4 was the RECON-IV, an improved version of the American RECON-III. The 8A4 itself is an upgraded version of the American AMETEK 2006, and the 7B8 is an improved version of the 8A4.
The Seafox is an anti-mine remotely operated vehicle (ROV) manufactured by German company Atlas Elektronik to locate and destroy ground and moored mines. There are two versions and a training version. The orange Seafox-I "inspection" variant has sonar and an Inertial navigation system, and the black Seafox-C "combat" round has a 1.4 kg shaped charge warhead. The system is in service with eleven navies across seventy platforms.The SeaFox is an advanced design of an Expendable Mine Disposal Vehicle or EMDV. The SeaFox comes with a control panel to help the user locate and destroy the mines. The SeaFox has a low life cycle cost meaning it has very low maintenance costs and does not cost much to rebuild if destroyed. The main target for the SeaFox is unexploded mines that pose a danger to ships and other vessels that might travel along the route. The SeaFox communicates with the ship via a fiber-optic that connects into a TV for the captain to view the mine. The Seafox also has a special launcher and retrieval system that it uses. Together the console and launcher help navy's around the world conduct damage estimation, route surveys, maritime boundary control, intelligence and harbor surveillance missions. The SeaFox primarily uses a transponder called dead reckoning. Dead reckoning is a pressure sensor on the SeaFox. The Seafox Drone has also been used on the MH-53 helicopter.
The Knifefish is an autonomous unmanned underwater vehicle (UUV) under development by General Dynamics Mission Systems and Bluefin Robotics for the United States Navy. It is a propeller-driven minesweeping robot designed to replace the Navy's trained dolphins and sea lions after the retirement of the 50-year-old Marine Mammal Program in 2017. The Knifefish was first unveiled at a Navy exposition in April 2012, and is intended to operate in concert with the Navy's littoral combat ships (LCS) as part of a specialised counter-mine system. The Navy plans to begin sea trials of the Knifefish in 2015, and to enter it into active service in 2017.
Bluefin Robotics is an American robotics company, headquartered in Quincy, Massachusetts, which specialises in the design and manufacture of military and civilian autonomous underwater vehicles (AUVs) and related technology. The company was founded in 1997, and became a wholly owned subsidiary of Battelle Memorial Institute in 2005. Its products include the Bluefin-21 underwater search robot and its military derivative, the Knifefish minesweeping AUV, which entered service with the United States Navy in 2017. Bluefin was involved in the development of several advanced Navy projects, including the Black Pearl AUV and the Proteus optionally-manned submersible.
The Rainbowfish class bathyscaphe is a Chinese deep submergence vehicle under development in 2015 and originally scheduled to enter service in 2019, but has since been postponed after 2020.

CSSC unmanned vehicles (UUV)s are uncrewed vehicles developed in the People's Republic of China (PRC) by China State Shipbuilding Corporation (CSSC), most of which are in service with various Chinese governmental agencies/departments, and government-owned enterprises.
Hadal ARV is a type of very little known unmanned underwater vehicle (UUV) built in the People's Republic of China (PRC). ARV stands for Autonomous Remotely-controlled Vehicle, an idea pioneered in China by Shenyang Institute of Automation (SIA) of Chinese Academy of Sciences (CAS), and SIA is also the developer of Hadal ARV and its predecessor Arctic ARV, as well as Hadal 1 ARV, the successor of Hadal ARV. Hadal and its predecessor Arctic series ARVs are the Chinese counterparts of Nereus hybrid unmanned underwater vehicle, because just like Nereus hybrid UUV, these ARVs can operate both as an AUV or a ROUV.
