At MBARI, Kanna’s role (2005 to 2013) as the Principal Researcher for Autonomy and a PI, to conduct research in brining advanced methods in AI for marine exploration. Towards this end, he and his group worked on designing, testing and operating an embedded autonomous controller for adaptive sampling for AUVs (autonomous underwater vehicles), which can sense, plan and act performing cognitive functions similar to how humans perform tasks. The Teleo-Reactive EXecutive (T-REX) is the only operational plan synthesis, repair and execution system for oceanographic observations. It has been used onboard AUVs in California, Norway and Portugal. A version of T-REX was also used for ship-based operations of AUVs and UAVs (unmanned aerial vehicles) in the REP-15 exercises off of the Azores in the mid-Atlantic. T-REX is an open-source planning and execution framework, which means within it, various forms of logical reasoning methods including those in Machine Learning can be incorporated.

The research efforts at MBARI also leaned towards providing an information driven platform for maritime situational awareness. The ODSS (Oceanographic Decision Support System) coupled the lessons learned from the MAPGEN system for use on Mars with MAPGEN with the unique features of data collection, localization and near real-time data streams from mobile and immobile robots in the ocean.
