Creating the Double EagleSAROV a hybrid AUV/ROV

HistoryIt all started 100 years ago

1910 – First Swedish developed torpedo

1976 – Saab built an advanced WROV

1981 – SUTEC is formed

1985 – First 360° maneuverability ROV

1989 – First AUV delivered

1991 – Saab acquires SUTEC

1993 – First survey ROV system with autopilot demonstrated

2003 – Double Eagle MkIII 6+ knots survey ROV

2007 – Seaeye Acquired

2008 – Double EagleSAROV

Hybrid AUV/ROV

SAAB UNDERWATER SYSTEMSThe vehicles is equipped with an unique 360 degrees control system enabling the vehicle to operate in any direction, noseup or down or anything between, even totally upside down under full control and with very good stability

SUBROV

Long endurance search and survey operations

60+ Operational systems worldwide

Fixed or Mobile installations

AUV Development

Torpedo shaped long range survey AUV

First sea trial December 2000

Equipped with profiler and SAS sonar

Development of terrain navigation

Observation Class (eyeball)

Inspection Class

(e.g. Diver Support, Search & Salvage, NDT Inspection)

Survey Vehicles

(e.g. Pipeline Survey)

Work Vehicles

(e.g. Drill Support, IRM, Submarine Rescue)

MISSION - PLANNING AND EXECUTION

Missions consist of Actions:• Sequential discrete events

• Well-known transition models

• For example: Transport, Search, Docking

Actions consist of Behaviors:• Parallel continuous control

functions

• Activated during runtime

• Example: AvoidObstacle, GotoWaypoint(W), GetGPS-position

BEHAVIOR-BASED CONTROLEach behavior can voice its opinion on best course of action

Behavior responses as utility functions

An arbitration mechanism coordinates behaviors to maximize utility

Dynamic activation level and static priority determines behavior influence.

Reference values passed to low-level control system:roll, pitch, heading and speed in x, y, z.

BEHAVIOR-BASED CONTROL: EXAMPLE

1: Track following:Follow track closely for best sonar coverage and platform stability.

2: Waypoint navigation:Ensure that the overall goal of reaching the next waypoint is met

3: Obstacle avoidance:Steer the vehicle clear of obstacles. Activation rises with hazard proximity.

4: Avoid past:Influences the vehicle to favor a new path to avoid getting stuck in circular behaviors

5: Emergency stop:Influences the vehicle cruising speed to decrease with obstacle proximity. Ultimately forces the vehicle to a full stop if to close.

OBSTACLE AVOIDANCE

Responses are weighted together and the maximum is chosen as the response to send to control system
