Autonomous Surface Vehicle-ASVWhat is it?

Vehicle (boat) that can operate with no human interaction

Why do we need them?ASVs can operate in environments that are dangerous to

humans (nuclear, biological, space, etc)

5

ObjectiveImprove current ASV for the Summer 2012

Association for Unmanned Vehicle Systems International annual

RoboBoat Competition

6

RoboBoat CompetitionPrimary Tasks

Speed Test Locate and complete a

straight course as fast as possible

Navigation Test Navigate a course of

buoys with several turns and obstacles

Secondary Tasks

7

Solution ApproachDetermine/purchase sensors that provide

competitive performanceDetermine a navigation logicIntegrate all sensorsTest and evaluate sensors and navigation

logicDebug and modify as required

Install electronics on boatTest and evaluate ASV

Computer VisionPrimarily for buoy

color detectionInputs directly to

onboard computerVision information

only extracted when LiDAR detects object

Sensor Gimbal MountRequired to keep

LIDAR and cameras level

Uses Ardupilot gyro and accelerometer sensors to detect motion

12

Navigation LogicDefined scenarios

based on:Distance to buoysColor of buoysApproach angle

LiDAR as primary sensor

Computer Vision as secondary sensor
