TRANSCRIPT

  • 1. Merging Technologies Creating theDouble Eagle SAROV a hybrid AUV/ROVJan Siesj March 4 2009 UI 2009

2. History It 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+ knotssurvey ROV
  • 2007 Seaeye Acquired
  • 2008 Double Eagle SAROV Hybrid AUV/ROV

3. SAAB UNDERWATER SYSTEMS The vehicles is equipped with an unique 360 degrees control system enabling the vehicle to operate in any direction, nose up or down or anything between, even totally upside down under full control and with very good stability SUBROV 4. 5. Long endurance search and survey operations 60+ Operational systems worldwide Fixed or Mobile installations 6. AUV Development

  • Torpedo shaped long range survey AUV
  • First sea trial December 2000
  • Equipped with profiler and SAS sonar
  • Development of terrain navigation

7. Seaeye Electric ROV SystemTypes & Applications

  • Observation Class (eyeball)
  • Inspection Class
  • (e.g. Diver Support, Search & Salvage, NDT Inspection)
  • Survey Vehicles

  • 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

FollowSearchPattern FollowSeaBed AvoidObstacle Transport Search GotoWaypoint(W 1 ) AvoidObstacle GetGPS-position 1 Transport GotoWaypoint(W 2 ) AvoidObstacle GetGPS-position 4 Docking Docking 2 3 13. BEHAVIOR-BASED CONTROL

  • Each 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.

Reference value Sensor data Behavior Arbitration Sensor data Sensor data Behavior Behavior p1 p2 p3 Priority 14. 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.

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