Features

Power-efficient, electromechanical manipulators
300m working depth for hours at a time
Flexible one¹- or two-armed system can be teleoperated or controlled with optional supervised autonomous and semi-autonomous control
Modular design enables integration with existing inspection-class underwater vehicles

1 Manipulators are designed for neutral buoyancy at each link, enabling them to maintain a state of buoyancy and control regardless of configuration (i.e., one vs. two-armed).

Benefits

Reduces the need to put divers into the water for light-work missions
Minimal training required for easy operation and deployment
Eliminates the added weight, size, expense, and oil leakage risks of hydraulic power unit (HPU) systems
Manipulators have fewer sealed surfaces than comparable hydraulic systems, reducing potential maintenance costs and the risk of system downtime due to failure

Exceptional Capabilities

Demonstrated 1000m+ working depth
Electronically driven, energy-saving system
Lightweight, compact design
Single-arm or dual-arm configurations (6 DoF + gripper per arm)
Integrated gripper with semi-autonomous, tool-grasping capabilities for quick tool changes
Neutral buoyancy improves ROV/manipulator balance and control
Sealed design protects the electrical system from water ingress and contamination
Multi-level corrosion management system
Open architecture supports ROS communication protocols
Designed to integrate with existing ROVs
Teleoperated control
Supervised autonomous and semi-autonomous capable
