We are preparing a workshop on Robotic Manipulation of Deformable Objects (ROMADO) at IROS 2020. Notice that IROS 2020 will not be held in-person due to the COVID-19 pandemic. Instead, the contents of the conference will be provided on the IROS On-Demand platform. This platform will be used to present the contents of this workshop.
This year the access to all the conference contents is free, check details at IROS 2020 web.
More details about the workshop with the list of invited speakers and contributed papers can be found in the workshop web. In the meanwhile, take a look to this introduction video of the workshop ROMADO:
Title: RGB-D tracking and optimal perception of deformable objects Author: Ignacio Cuiral-Zueco, Gonzalo López-Nicolás Journal: IEEE Access, vol. 8, pp. 136884-136897, 2020.
Abstract: Addressing the perception problem of texture-less objects that undergo large deformations and movements, this article presents a novel RGB-D learning-free deformable object tracker in combination with a camera position optimisation system for optimal deformable object perception. The approach is based on the discretisation of the object’s visible area through the generation of a supervoxel graph that allows weighting new supervoxel candidates between object states over time. Once a deformation state of the object is determined, supervoxels of its associated graph serve as input for the camera position optimisation problem. Satisfactory results have been obtained in real time with a variety of objects that present different deformation characteristics. Download paper
Brayan Stiven Zapata Impata (University of Alicante, Linkedin) is going to defend his PhD Thesis on the topics of COMMANDIA under the supervision of Professor Pablo Gil. The dissertation is planned on September, 17th, 2020 in Alicante, Spain.
Author: Brayan Stiven Zapata Impata Supervisor: Pablo Gil Vazquez Dissertation date: September 17th, 2020. Title: Robotic manipulation based on visual and tactile perception. Abstract: In this thesis, we provide solutions for various challenges in robotic manipulation. Applying visual perception, a robotic assistant could find grasps on unknown objects. With the use of tactile perception, the robot could predict whether the grasp is stable and even identify in which direction might be slipping the grasped object. As a result, the robot could trigger strategies for keeping the object stable. Finally, integrating our tactile data generation system with the rest of the modules, the assistive robot could feel the grasps before actually moving itself, so less objects would be dropped due to visually stable grasps that are actually slippery.
Title: Robotic workcell for sole grasping in footwear manufacturing Author: Guillermo Oliver, Pablo Gil, Fernando Torres Conference: 25th Int. Conf. on Emerging Technologies and Factory Automation (ETFA), Vienna (Austria), 8-11 September 2020.
Abstract: The goal of this paper is to present a robotic workcell to automate several tasks of the cementing process in footwear manufacturing. Our cell’s main applications are sole digitization of a wide variety of footwear, glue dispensing and sole grasping from conveyor belts. This cell is made up of a manipulator arm endowed with a gripper, a conveyor belt and a 3D scanner. We have integrated all the elements into a ROS simulation environment facilitating control and communication among them, also providing flexibility to support future extensions. We propose a novel method to grasp soles of different shape, size and material, exploiting the particular characteristics of these objects. Our method relies on object contour extraction using concave hulls. We evaluate it on point clouds of 16 digitized real soles in three different scenarios: concave hull, k-NNs extension and PCA correction. While we have tested this workcell in a simulated environment, the presented system’s performance is scheduled to be tested on a real setup at INESCOP facilities in the upcoming months.
Title: Blind Manipulation of Deformable Objects Based on Force Sensing and Finite Element Modeling Author: Jose Sanchez, Kamal Mohy El Dine, Juan Antonio Corrales, Belhassen-Chedli Bouzgarrou and Youcef Mezouar Journal: Frontiers in Robotics and AI. 09 June 2020. 7:73. doi: 10.3389/frobt.2020.00073 Abstract: In this paper, we present a novel pipeline to simultaneously estimate and manipulate the deformation of an object using only force sensing and an FEM model. The pipeline is composed of a sensor model, a deformation model and a pose controller. The sensor model computes the contact forces that are used as input to the deformation model which updates the volumetric mesh of a manipulated object. The controller then deforms the object such that a given pose on the mesh reaches a desired pose. The proposed approach is thoroughly evaluated in real experiments using a robot manipulator and a force-torque sensor to show its accuracy in estimating and manipulating deformations without the use of vision sensors.
