A team from Portugal have created a catamaran like boat that is used for monitoring rivers. Using ROS as the operating system. The boat also uses 3D mapping, sonar and tilting laser scanner amongst other technologies.
Waypoints can be set and the robot will navigate autonomously to the waypoint, while avoiding obstacles above and below the surface of the water.
The boat also has a landing pad for a 6 rotor UAV that provides and aerial point of view.
See the video below for a more detailed explanation.
Nice job everyone!
