TRIDENT Project overview • PHASE I (Survey) -The Autonomous Surface Craft (ASC) is launched to carry the Intervention Autonomous Underwater Vehicle (I-AUV) towards the area to be surveyed. -Then, the I-AUV is deployed (1) and both vehicles start a coordinated survey path (2) to explore the area. -The ASC/I-AUV team gathers navigation data for geo-referencing the measurements (seafloor images and multibeam bathymetry profiles). -Finally, the I-AUV surfaces (3) and contacts to the end user to set-up and acoustic/optical map of the surveyed area. -Using this map, the en user selects a target object (an object of interest) as well as a suitable intervention task (grasping, hooking, etc...). - ISR-UC potential contribution on this topic
TRIDENT Project overview • PHASE II (Intervention) -After selecting the target, the ASC/I-AUV team navigates towards the target position. Then, the ASC performs dynamic position (4) while keeping the I-AUV inside the USBL cone of coverage. -Then, the I-AUV performs a search (5) looking for the Target of Interest (ToI). When the object appears in the robot field of view, it is identified and the I-AUV switches to free floating mode using its robotic arm as well as the dexterous hand to do the smart manipulation (6). -Finally (7), the I-AUV docks to the ASC before recovery. - ISR-UC potential contribution on this topic

TRIDENT2: Example of Application Phase I - TO1 • Motivation • Both vehicles are deployed in the mission environment; • Collaborative exploration strategy to map the unknown environment; • Approach • Adapt the collaborative trained exploration strategies parameters to unknown environment contexts; • Simulation environment – Learning phase • Environment context A –>Demo: AUV1 & AUV2 exploration strategy parameters A • Environment context B–>Demo: AUV1 & AUV2 exploration strategy parameters B • Real world experimental environment– Inference phase • Environment context analysis • -Description of the perceived environment context as a probabilistic combination of previously known/learned environment contexts. • Estimation of the ponderated exploration strategy parameters of the new unknown environmental context. 2/29
TRIDENT2: Example of Application Phase II - T02, T03, T04, T05 • Flow chart that encloses two cases: • the first one is a known context where the object (target) is known a priori • Imitation of previous knowledge (trajectories) taking into consideration the object pose (to generate hypothesis of possible grasps that influences also the trajectories; • the second, the object is not known (during exploration, rocks/stones, tubes, object that was not used in the learning phase) • *in this case a generalization process by similarities is used. The object is segmented in such way that is possible to generate known shapes (primitives) that composes the object, so that the grasp planning can be applied to that shape, including the trajectories. * Example of similarities: Given a unknown object (not learned before), then its shape is decomposed in primitives (superquadrics) to approximate the shape into known geometric shapes to be possible to generate a specific grasp for some of the segmented parts: Known geometrical shapes and its pose can generates known (learned) grasps and trajectories
TRIDENT2: Example of Application Phase III – TO6 • Motivation • Both vehicles working together and under coordination with the two robotic arms to assemble multi-elements objects; • Approach • Cooperative manipulation movements and assembly strategy described at a symbolic kevel • Simulation environment – Learning phase • Multi-elements object configuration A Object assembly demo 1, 2 ... N • Extraction of the finite set of primitives – task dictionary • -Characterization of each primitive using lower level signals (trajectories, control signals, …) • Extraction of a generalized task structure (general primitive sequence) • -Extraction of some of the primitive sequence rules (required precedence, …) - grammar rules of the task primitives dictionary • Real world experimental environment– Inference phase • Multi-element object configuration recognition Primitive sequence generation 2/29
Open Issues for Discussion • What are the signals provided by the other project modules that can be used for learning in T01, T02, T03 ? : • Combined trajectories of the Arm and UAV ? • Combined trajectories/pose of object, the gripper, the Arm and UAV? • Controls signals and trajectories accomplished in the demonstrations ? • What are the object detection features provided by the environment mapping module? • Target object tracking - 2D and 3D cases? • Object Detection (template matching, shape approximation) – Known and unknown objects? • Automatic Segmentation (floor, 3D object map) ? • Intervention for 3D case (already tested?) 2/29
