The best of digital technologies are brought together to meet the challenges of modern military operations in the new R7 Compact ROV from Exail.

Multiple services, including military navies, special forces, coast guards, customs agencies, rescue services, and police departments are looking for a versatile, compact, user-friendly system for their missions. 

The R7 has been designed to meet these requirements. Despite its space-efficient size, the R7 can fulfill a wide range of missions, such as: search and rescue, black box recovery, retrieval of objects for investigative purposes, assistance to divers, detection, identification, and depollution of unexploded ordnance (UXOs), harbour surveillance and protection.

Easy to Deploy and Operate Anytime, Anywhere

The next-generation ROV is very compact, measuring only 78cm in length and weighing 32kg. It is easy to transport and deploy by a team of just two people. 

Typically, each system includes an electrical power unit, a 327 m long umbilical cable, an R7 ROV vehicle, and a control unit that includes guidance controls and a mobile console that displays data from the ROV and its sensors.

To achieve such versatility, Exail conceived the R7 as a sturdy and lightweight platform, with a digital architecture that enables  easy integration of high-performance sensors and a wide range of equipment based on the mission at hand for more versatility. 

In order to provide its end users with the  best data while operating in the most challenging conditions, the R7 boasts an unparalleled power-to-weight ratio and agility, thanks to four vectored horizontal thrusters and three vertical thrusters. It can carry significant payloads and remain operational even in the presence of strong currents.

A Comprehensive Set of Equipment for Increased Versatility

One of the main qualities of the R7 is its extensive equipment. It comes equipped from the factory with high-performance full HD cameras and a powerful 4x zoom, providing high quality pictures even in  low-light conditions. 

The optical sensors are capable of real-time image enhancement to compensate for water turbidity, providing operators with incredibly sharp images. These state-of-the-art optronic sensors are complemented by two 5,000-Lumen LED projectors to ensure powerful illumination in all circumstances.

In underwater environments with low visibility, sonar remains the reference sensor. The R7 can be equipped with imaging sonars, navigation sonars, and side-scan sonars. Exail recently qualified the integration of a Doppler Velocity Log (DVL) for greater ROV movement precision. 

The R7 can also be equipped with a multifunctional arm for object manipulation. The choice of a digital architecture will facilitate future developments of the ROV, allowing the R7 to adapt to operators’ evolving needs for decades to come.

An Intuitive Interface for Easy Operations

One of the main advantages of the R7 is its intuitive Human-Machine Interface (HMI). The ROV’s and sensors’ data are displayed on two 15” touchscreens that remains highly readable even in bright light, while a multifunction joystick provides vehicle guidance. 

Operational Even in Strong Currents

Operating Exail’s R7 is straightforward, and can be done from a land-based point or a very small vessel. Once the ROV is in the water, the operator activates the seven thrusters of the R7, as well as the sensors and projectors. 

The vehicle then begins its mission while transmitting data in real time to the operator. It can cover a large search area and operate at depths of over 300m, even in strong current conditions, ensuring the success of its missions.

“Tests have shown that the R7 is naturally agile, fast, enduring, and above all, incredibly stable on all axes,” said Philippe Roumegue, Sales Director at Exail. “It can maneuver through narrow openings in order to enter a wreck or orient itself nose-up to inspect a hull. Very few ROVs can achieve such performance today.” 

This outstanding performance is achieved through the coupling of the motors with a state-of-the art Attitude and  Heading Reference System (AHRS) in order to enhance the ROV stability and the capacity to accurately control its pitch and roll.

“The digital architecture of this next generation ROV explains its outstanding versatility. Thanks to it, we have been able to design a drone that caters to all the needs of our clients. Simply choose from the vast array of equipment and sensors available for installation, make the necessary connections, and start the mission. It’s as simple as that,” assured Roumegue.
