Terrain-relative navigation helped Perseverance land autonomously on Mars. Now it’s time to test a similar system while exploring another frontier.
Called Orpheus, this new class of submersible robot will showcase a system that will help it find its way and identify interesting scientific features on the seafloor.
Orpheus’ version of vision-based navigation is called visual-inertial odometry, or xVIO, and it works by using a system of advanced cameras and pattern-matching software along with instruments that can precisely measure its orientation and motion.
