2G Robotics has developed a set of libraries and a user interface for the Linux operating system. Now when performing high detailed underwater inspections of bridges, dams and other underwater infrastructure users have a choice of operating platform.
The high precision measurement capability of the laser scanner makes it an ideal sensor for use with autonomous underwater vehicles (AUVs). As the use of AUVs for close range and high detail inspection increases, the benefits of using sonar for navigation and mapping diminish. Sonar is excellent for measuring over long distances particularity in high turbidity (murky) water. However, since the acoustic pulse diverges as it travels through the water, it is not capable of the resolution that laser scanning can achieve. In addition, the speed of sound in water is far slower than that of light. The ULS-100 captures over a thousand measurements per second. This high update rate increases the localization confidence level meaning that the position of the vehicle can be determined with less error.
