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)

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

Sensor Gimbal MountRequired to keep
LIDAR and cameras level
Uses Ardupilot gyro and accelerometer sensors to detect motion

Navigation LogicDefined scenarios
based on:Distance to buoysColor of buoysApproach angle
LiDAR as primary sensor
Computer Vision as secondary sensor
