Guardian® Sea Class
Underwater Robot
Underwater Mobile Manipulation
The Sarcos Guardian Sea Class underwater manipulation robot delivers human-like manipulation capabilities in complex and often dangerous underwater environments.
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
