Object modeling using a ToF camera under an uncertainty reduction approach
(2010)
Text en actes de congrés
Accés obertTime-of-Flight (ToF) cameras deliver 3D images at 25 fps, offering great potential for developing fast object modeling algorithms. Surprisingly, this potential has not been extensively exploited up to now. A reason for ... -
OCRA – An ontology for collaborative robotics and adaptation
(2022)
Article
Accés obertIndustrial collaborative robots will be used in unstructured scenarios and a large variety of tasks in the near future. These robots shall collaborate with humans, who will add uncertainty and safety constraints to the ... -
On inferring intentions in shared tasks for industrial collaborative robots
(2019)
Article
Accés obertInferring human operators' actions in shared collaborative tasks, plays a crucial role in enhancing the cognitive capabilities of industrial robots. In all these incipient collaborative robotic applications, humans and ... -
Plant leaf imaging using time of flight camera under sunlight, shadow and room conditions
(2012)
Text en actes de congrés
Accés obertIn this article, we analyze the effects of ambient light on Time of Flight (ToF) depth imaging for a plant’s leaf in sunlight, shadow and room conditions. ToF imaging is sensitive to ambient light and we try to find the ... -
Reward-weighted GMM and its application to action-selection in robotized shoe dressing
(Springer, 2017)
Text en actes de congrés
Accés obertIn the context of assistive robotics, robots need to make multiple decisions. We explore the problem where a robot has multiple choices to perform a task and must select the action that maximizes success probability among ... -
Robot explanatory narratives of collaborative and adaptive experiences
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertIn the future, robots are expected to autonomously interact and/or collaborate with humans, who will increase the uncertainty during the execution of tasks, provoking online adaptations of robots' plans. Hence, trustworthy ... -
Robotic leaf probing via segmentation of range data into surface patches
(2012)
Text en actes de congrés
Accés obertWe present a novel method for the robotized probing of plant leaves using Time-of-Flight (ToF) sensors. Plant images are segmented into surface patches by combining a segmentation of the infrared intensity image, provided ... -
Robotized plant probing: leaf segmentation utilizing time-of-flight data
(2013)
Article
Accés obertSupervision of long-lasting extensive botanic experiments is a promising robotic application that some recent technological advances have made feasible. Plant modeling for this application has strong demands, particularly ... -
Robots and IoT devices for assistive automation
(2019)
Report de recerca
Accés obertIn recent years, we live every day in an ever more connected world. This phenomenon has developed the technologies of the Internet of Things (IoT). At the same time, advances in robotics now make it possible to have ... -
Segmenting color images into surface patches by exploiting sparse depth data
(2011)
Text en actes de congrés
Accés obertWe present a new method for segmenting color images into their composite surfaces by combining color segmentation with model-based fitting utilizing sparse depth data, acquired using time-of-flight (Swissranger, PMD CamCube) ... -
Task-driven active sensing framework applied to leaf probing
(2018-04-01)
Article
Accés obertThis article presents a new method for actively exploring a 3D workspace with the aim of localizing relevant regions for a given task. Our method encodes the exploration route in a multi-layer occupancy grid map. This map, ... -
Task-oriented viewpoint planning for free-form objects
(Universitat Politècnica de Catalunya, 2016-07-28)
Tesi
Accés obertThis thesis deals with active sensing and its use in real exploration tasks under both scene ambiguities and measurement uncertainties. While object modeling is the implicit objective of most of active sensing algorithms, ... -
Teaching a robot where doors and drawers are and how to handle them
(2023)
Text en actes de congrés
Accés obertWe address the problem of teaching a service robot to detect doors and drawers in indoor environments. We propose a robust and accurate method in which a human demonstrates to the robot how to open doors and drawers that ... -
ToF cameras for active vision in robotics
(2014)
Article
Accés obertToF cameras are now a mature technology that is widely being adopted to provide sensory input to robotic applications. Depending on the nature of the objects to be perceived and the viewing distance, we distinguish two ... -
ToF cameras for eye-in-hand robotics
(2015)
Capítol de llibre
Accés obertA Time-of-Flight (ToF) camera is a relatively new type of sensor that delivers 3-dimensional images at high frame rate, simultaneously providing intensity data and range information for every pixel. It has been used in a ... -
Towards plant monitoring through next best view
(IOS Press, 2011)
Text en actes de congrés
Accés obertMonitoring plants using leaf feature detection is a challenging perception task because different leaves, even from the same plant, may have very different shapes, sizes and deformations. In addition, leaves may be ... -
Using ToF and RGBD cameras for 3D robot perception and manipulation in human environments
(Springer, 2014-10-01)
Article
Accés obertRobots, traditionally confined into factories, are nowadays moving to domestic and assistive environments, where they need to deal with complex object shapes, deformable materials, and pose uncertainties at human pace. To ...
