Electric subsea manipulator arms for ROVs
Remotely Operated Vehicles (ROVs) have revolutionized underwater operations across various industries, including offshore energy, maritime exploration, and underwater construction.
These submersible robots are equipped with advanced tools and sensors to perform a wide range of tasks in challenging underwater environments. Among the crucial components enhancing the versatility and effectiveness of ROVs are manipulator arms.
Expanding ROV capabilities with manipulator arms
With their advanced features, multiple versions, and precise control capabilities, Exail’s manipulator arms empower ROV operators to perform a wide range of tasks with efficiency, safety and precision, even in the most challenging underwater environments such as:
Inspection and maintenance of underwater structures.
Installation and retrieval of equipment and sensors.
Intervention in subsea operations, including repairs and adjustments.
Sample collection and retrieval for scientific research.
By integrating manipulator arms into ROV systems, operators can remotely execute intricate maneuvers and handle objects with dexterity, mimicking human-like movements in the underwater environment.
Exail's ROV arms: 7-Function and 5-Function
Exail offers two main types of electric manipulator arms for ROVs: the 7-function arm and the 5-function arm. Both types of arms come in multiple versions designed to meet specific operational requirements and offer distinct features and capabilities.
ARM 7E range: 7-Function arms
The 7-function arm provides a comprehensive solution for a wide range of subsea tasks. Its seven degrees of freedom enable enhanced maneuverability and flexibility, allowing ROVs to perform intricate operations with precision. This arm is ideal for applications requiring advanced manipulation capabilities, such as complex installations, precise adjustments, and delicate object handling.
Standard Version: The standard configuration provides optimal performance and flexibility for a wide range of subsea operations.
Mini Version: A more compact alternative suitable for ROVs with space limitations or applications where a smaller footprint is preferred.


ARM 5E range: 5-Function arms
The 5-function arm offers a more streamlined solution while still providing essential manipulation functionalities. With five degrees of freedom, this arm is suitable for various underwater tasks, including inspection, basic maintenance, and object retrieval. Its compact design makes it particularly suitable for ROVs operating in confined spaces or environments with limited maneuvering room:
Standard Version : offers a balance of performance and versatility for typical subsea tasks.
Mini Version: A compact variant designed for ROVs operating in tight spaces or performing tasks requiring precise movements with limited clearance.
Micro Version: The smallest variant optimized for micro-ROVs or applications where size and weight constraints are critical.
Which version to choose ?
The choice between the standard, mini, or micro version of each arm depends on factors such as operational requirements, space constraints, and payload limitations. While the standard versions offer standard performance and versatility, the mini and micro versions provide enhanced maneuverability and agility in confined spaces or specialized applications.
Operators can select the most appropriate arm variant based on their specific project needs, optimizing efficiency and performance in underwater operations.
