Autonomous robotic deep sea lander

TURTLE is an autonomous robotic deep sea lander, which has been developed by INESC TEC, the Autonomous Systems Laboratory (LSA) of the School of Engineering of the Polytechnic Institute of Porto (ISEP), the Portuguese Navy Research Centre (CINAV), and the companies ply and A. Silva Matos Metalomecânica (the latter was the leader of the consortium). TURTLE is a hybrid lander, being capable of staying at the bottom of the sea for long periods of time, but also of autonomously relocating itself and surfacing for maintenance operations. It is also able to dive and ascend with high-energy efficiency, and its autonomous capabilities allow for reduced operational costs and flexibility. TURTLE is the first deep sea robotic system fully developed at Portugal.
