History

GO Science Ltd was founded in 2002 [1] in Bristol, UK by a former BAe director of Underwater Systems, [2] and a founder of the Las Iguanas restaurant chain, [3] to develop a ‘ring wing’ Autonomous Underwater Vehicle (AUV). Initial funding was from the South West Regional Development Agency (SWRDA) in 2006. [4] In November 2008 ICON Corporate Finance [5] raised significant investment (19.4% [6] ) for GO Science from Kenda Capital, the manager of the Shell Technology Ventures Fund 1 (STVF) [7] with Kenda directors joining the board. The prototype vehicle was developed in the University of Bristol labs, then at Redhill Farm Business Park and later at Aztec West, outside Bristol. An office was opened at the SETsquared Business Acceleration Centre at the University of Bristol.

In September 2009 the company announced that it had won a £6m contract with an unnamed oil company. [8] This was later confirmed as Shell E&P, adding the challenge of a deepwater specification. Shell’s Chief Scientist Geophysics stated that the concept was to be tested "in earnest" for a few months whilst recognising the cost and acknowledging that "we’re happy to partner with others". [9] Shell provided the company with over £4 million of investment. [10] Subsequently GO Science announced it was under contract to "two very large companies". [11] In May 2012 the planned trials for Shell E&P consisted of a five vehicle trial in the Gulf of Mexico, USA, for the summer of 2012, with a larger trial of fifty vehicles in 2013. [12] Neither of these trials were undertaken.

Pressures on the company increased through 2012–13. STVF were looking critically at their investments, following a review of the portfolio companies by a senior Schlumberger executive in 2011. The GO Science accounts to the end of 2012 showed a loss of £0.3m. [13] In June 2013 the company applied for funding from the West of England Going for Growth campaign. [14] At the same time the company’s commitments to Shell E&P, with regard to the planned trials, were slipping.

On 31 July 2013 GO Science Ltd was placed into administration at the request of STVF, due £2.5m with other creditors owed over £0.5m. Six of the thirteen staff were made redundant. However, ten potential buyers approached the administrators, BDO, and in September 2013 Thalassa Holdings Ltd agreed to pay £3.6m for the company. [15] At the close of 2013 the GO Science shareholders expected to receive Thalassa shares if "Go Science’s principal customer contracts are re-activated." [16] Thalassa, which possesses expertise in OBS, has made the acquisition "on what appear to be extremely favourable terms" according to AimZine. [17] In 2014 it was revealed that Thalassa had paid rather less for GO Science, $2.9m, and registered the group in the British Virgin Islands. [18] Thalassa appointed a previous Managing Director of Saab Seaeye Ltd as CEO, the company was renamed Autonomous Robotics Ltd and relocated to Warminster, UK. [19]

In 2019, the company had seven employees. [20]

Ocean Bottom Seismic

The initial markets investigated included military, environmental and exploration applications. In June 2008 the company committed to developing an application for seabed seismic sensors (Ocean Bottom Seismic, OBS) for oil and gas exploration. [21] A "swarm" of autonomous vehicles, as a self-deploying and -recovering sensor grid, offers potential efficiency savings over cables or populating a grid with sensors one-at-a-time by a remotely operated underwater vehicle (ROV). The ambition at this time was for the first production vehicles to be operational by 2010. [22] Thalassa have described this technology as having the "potential to have a massive impact on the way marine seismic data is collected". [23]

Autonomous Underwater Vehicle

GO Science's RHyVAU (Ring Hydro Vessel Agent Under-liquid) was an autonomous underwater vehicle (AUV), a type of unmanned underwater vehicle (UUV).

The design was that of a ‘ring wing’, a hydrofoil section rotated about the axis to form a toroid. Of fixed chord, the leading edge was also swept aft toward the top and bottom of the toroid. This form can generate lift in descending or ascending glide paths. With twin thrusters mounted inside the duct, the vehicle was very manoeuvrable in comparison to a torpedo type design, for a slight drag penalty. The first of a number of international patents was filed in October 2006. [24]

The prototype vehicle had an outside diameter of 533mm, 21" being a common torpedo size, 25 kg mass and a 1.1 kWh lithium polymer battery supplying two 2 kW thrusters and was capable of 8 knots. [25] Trials were conducted in enclosed waters around the UK and in the Netherlands. The production version was proposed to cost US$30–60,000 each, was designed to operate in depths in excess of 2,000 m [26] and "can organize itself into a "swarm" with up to 2,500 units in a coordinated autonomous group" [27] up to 100 km from the launch point. [28] As well as the powered version (called Contueor), the company considered glider versions (Indago), towed versions (Aspicere), and aerial versions (µRaptor). [29]

Autonomous Robotics have been working on a more conventionally shaped AUV for the OBS application, and presented a full scale model of the new vehicle in 2015. ARL predicts a tenfold improvement in the deployment and recovery rates over ROV placement, with the intention to use 3,500 nodes in a system, deploying for up to 60 days in up to 3,000m of water.

Micro air vehicle

A micro air vehicle (MAV), or micro aerial vehicle, is a class of miniature UAVs that has a size restriction and may be autonomous. Modern craft can be as small as 5 centimeters. Development is driven by commercial, research, government, and military purposes; with insect-sized aircraft reportedly expected in the future. The small craft allows remote observation of hazardous environments inaccessible to ground vehicles. MAVs have been built for hobby purposes, such as aerial robotics contests and aerial photography.

Autonomous underwater vehicle Unmanned underwater vehicle with autonomous guidance system

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.

Underwater glider A type of autonomous underwater vehicle that uses small changes in its buoyancy to move up and down and uses wings to convert the vertical motion to horizontal, propelling itself forward with very low power consumption

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 any vehicles that are able to operate underwater without a human occupant. These vehicles may be divided into the two categories of remotely operated underwater vehicles (ROUVs), which are controlled by a remote human operator, and autonomous underwater vehicles (AUVs), which operate independently of direct human input. Sometimes only vehicles in the second category are considered a kind of robot, but those in the first category are also robots similar to surgical robots, which also mostly require an operator.

Robot fish

A robot fish is a type of bionic robot, which has the shape and locomotion of a living fish. Since the Massachusetts Institute of Technology first published research on them in 1989, there have been more than 400 articles published about robot fish. According to these reports, approximately 40 different types of robot fish have been built, with 30 designs having only the capability to flip and drift in water. Most robot fish are designed to emulate living fish which use Body-caudal fin (BCF) propulsion. BCF robot fish can be divided into three categories: Single Joint (SJ), Multi-Joint (MJ), and smart material-based design. The most important parts of researching and developing robot fish are advancing their control and navigation, enabling them to 'communicate' with their environment, making it possible for them to travel along a particular path, and to respond to commands to make their 'fins' flap.
