Press Release: Robotic Submarine Running Debian Wins International Competition

Robotic Submarine Running Debian Wins International Competition This August, a team of 35 undergraduate students from Cornell University sank the competition at the 12th annual Autonomous Underwater Vehicle Competition[0], sponsored by the Association of Unmanned Vehicle Systems International and the Office of Naval Research. The competition takesplace in a large acoustic testing pool operated by the US Navy SPAWAR Systems Center. It calls for entries to pass through a gate, follow a path, ram a submerged buoy, fire through a square target with small torpedoes, drop markers into bins containing simulated targets, recover a PVC target and surface through an octagon shape, all without human intervention. The Cornell Autonomous Underwater Vehicle Team (CUAUV)[1] took first place by completing the entire course at the competition, a feat not seen since MIT won in 2002. This was Cornell's first victory since 2003. Cornell's vehicle, named "Nova," runs a custom software stack on top of a single board computer running Linux and relies heavily on Debian. "Debian works amazingly well for us," said Benjamin Seidenberg, CUAUV's new software team leader. "Not only do we use it on the vehicle, we also run it on the computers in our lab and our servers, and use it to develop our custom electronics." Seidenberg, who also handles IT issues for the team, said that they consolidated on Debian three years ago. "When I joined the team, we had computers running Windows XP, Windows Server, Debian, Ubuntu, FreeBSD and Gentoo. Now we've settled on Debian for the sub and the servers; our lab workstations dual boot Debian and Windows. It's a lot easier to manage, and it's great to be able to develop in the same environment that the submarine runs." The team also uses other open source software on their vehicle such as OpenCV for image processing and libdc1394 for video capture. According to Arseney Romanenko, another member of the software team, these libraries are essential for doing vision processing in an embedded environment; they are fast and lightweight which translates into significant power savings.
