Ship actuator ERLA

for ROVfor AUVselectric

The ERLA-Electrical Rotary & Linear Actuator is a servo rotary and linear actuator, designed for operations in demanding environments.

• THRUST

Thrust capability : up to 80 kg

• TORQUE & ROTATION SPEED

16 N.m (max) and 8 seconds for a complete rotation (360°)

• DEPTH RATE

Immersion to 600 m max depth rate

• ROBUSTNESS

Less maintenance, more reliability

The ERLA-Electrical Linear Actuator is an underwater actuator combining rotary motion and linear motion in a compact and robust format. Designed for subaquatic environments to a maximum of 600-meter depth rate, it offers precision thrust capability and real time position feedback.

The ERLA is versatile and modular. It integrates easily to underwater robots (ROV, AUV) or other platforms for a variety of applications: objects manipulation, sampling, structure adjustments or embedded tooling.

Like our robotic manipulator arm, the EMA 5F, the ERLA can be equipped with different tools as interchangeable jaws (T-bar, parallel, grabber, cutter, etc…). In this case, the linear motion allows opening or closing of the jaw, whereas the rotary motion allows to adjust the orientation.
ERLA is a modular solution which adapts to a number of applications, according to your specific needs.

Actuators designed to comply to your specific needs:
All industrial or underwater applications have specific technical requirements. It is why we develop customized solutions, in collaboration with your teams.
Our R&D department supports you step by step, from the analysis of your constraints to the design of customized actuators which perfectly fit your environment, your target performances and your integration constraints.

Customize your solution according to various criteria:

• Motion / rotation speed
• Applied thrust / torque
• Range
• Depth
• Connector type
• Mechanical termination

Features:

• Designed for applications with large thrust where precision and motion / rotation control are needed.
• Position feedback in velocity and position mode.
• 1 connector available for add-on capacity (additional actuator, camera, projector…).
• With embedded electronic controller (no external POD required).
• Versatile and easy to integrate.

The ERLA integrates an embedded controller with:

• Programmable position or velocity commands
• Real time position feedback
• Smooth and precise control, even in extreme conditions
• Modular connectivity

Its additional connector allows:

• Adding external equipment (camera, sensor, projector, sonar, etc…),
• Chaining other actuators (ELA, ERA, ERLA) to build interconnected and scalable systems.

Easy to integrate:

• Quick integration in various submersible systems,
• Ultra compact design with excellent power vs bulk ratio,
• Guidance available from our team.

Actuator Commander Software:
The ERLA comes with a remote-control software. This user-friendly software allows (Windows® compatible):

• simple setting,
• real time monitoring,
• quick diagnosis of the system.
