Gripper with Scissor for ROV Underwater Manipulation

https://www.huayandynamicseal.com/gripper-with-scissor-for-rov-underwater-manipulation.html

ROV underwater operations often require more than simply moving or observing objects. During subsea manipulation and intervention tasks, the robotic arm may need to securely grip an object while also performing cutting operations. Using different tools for each task can make the operation more complicated.

Our Gripper with Scissor is designed as a versatile end-effector solution for ROV robotic arms and subsea robotic systems, combining gripping and scissor functions in one tool. It helps operators handle objects while also providing a scissor function for suitable cutting tasks.

Combined Gripping and Cutting for ROV Operations

A conventional ROV gripper is mainly used to grasp, hold, retrieve, or position underwater objects. However, some subsea manipulation tasks may also require a cutting function.

The Gripper with Scissor integrates these two functions into one ROV robotic arm accessory. The gripper can be used to hold objects, while the integrated scissor provides an additional cutting function when required.

This combination can support underwater tasks involving:

• Object gripping and handling

• Object retrieval and positioning

• Cutting operations

• Underwater manipulation

• Subsea maintenance and intervention tasks

• Handling objects in confined underwater environments

By combining gripping and scissor functions in one end effector, the ROV robotic arm can support a wider range of underwater manipulation tasks.

Designed for Flexible ROV Underwater Manipulation

During subsea operations, the robotic arm needs to interact with objects of different sizes and shapes. A suitable gripper therefore needs to provide both sufficient opening capacity and reliable gripping force.

Our Gripper with Scissor features a maximum gripper opening of 82 mm and a gripping force of ≥250 N, providing practical handling capability for various underwater manipulation tasks.

The scissor section has an opening of 27 mm, providing a dedicated cutting function within its designed working range.

With these capabilities combined, the tool can support ROV operators when a task requires both controlled gripping and cutting.

24V Electric Drive for ROV Robotic Arms

The Gripper with Scissor features a 24V rated voltage and 24W rated power, making it suitable for integration with compatible electrically operated subsea robotic arm systems.

The gripper's full opening time is ≤10 seconds, supporting controlled manipulation during underwater operations.

For ROV system integrators and equipment manufacturers, electrical specifications are important when evaluating compatibility between an end effector and the robotic arm system. The operating voltage, power requirements, mechanical interface, and control system should be considered together during integration.

Supporting Subsea Retrieval and Handling Tasks

ROVs and subsea robotic systems are used when direct human access to underwater environments is difficult or impractical. During underwater manipulation and intervention operations, the robotic arm needs to interact with objects in a controlled manner.

The Gripper with Scissor can be used as an ROV robotic arm accessory for tasks that involve holding and manipulating underwater objects, while the additional scissor function provides greater flexibility when cutting is required.

For example, when an underwater manipulation task involves an object that needs to be held and a separate cutting operation is required, a combined gripper and scissor end effector can provide both functions through the same tool.

A Practical ROV Robotic Arm Accessory for Subsea Applications

Choosing the right end effector depends on the specific ROV, robotic arm, working environment, and task requirements. For applications that involve both object handling and cutting, a combined gripper and scissor configuration can provide a practical solution.

Our Gripper with Scissor is developed as an end effector for subsea robotic systems where gripping and cutting functions are required in the same working tool.

With its 24V electrical design, 82 mm maximum opening, ≥250 N gripping force, and 27 mm scissor opening, it provides a combination of gripping and scissor functions for underwater robotic manipulation.

For ROV manufacturers, system integrators, and underwater equipment providers looking for a multifunctional ROV robotic arm accessory, our Gripper with Scissor offers a practical option for integrating gripping and cutting capabilities into subsea robotic operations.
