Title: Experiences With an RGB-D Object Dataset
Abstract:
In this talk, I will present our effort in developing the first dataset for RGB-D based object recognition. I will also discuss lessons learned from this work and how this might apply to grasping and manipulation datasets.

Title: Assessing grasp stability and object shape modeling based on visual and tactile data
Abstract:
I will talk about probabilistic approaches using real sensory data, e.g., visual and tactile, for learning models to assess grasp success (discriminative and generative) and understanding object shape which is important for grasp planning. I will also introduce a low-cost pipeline and database for reproducible manipulation research. Our approach combines an inexpensive generation of detailed 3D object models via monocular camera images with a state of the art object tracking algorithm.

Title: An open-access repository to share data and tools for the study of human and robotic hands: the HandCorpus initiative
Abstract:
The HandCorpus, is an open-access repository for sharing data, tools and analyses about human and robotic hands. The HandCorpus website represents a cross-platform and user-friendly portal for researchers interested in sharing datasets and/or exchanging ideas, regarding the most versatile end-effector known, the human hand. Over the last years the HandCorpus community has grown and consists now (September 2015) of five European Committee (EC) projects and more than 20 research groups, located across Europe and United States of America. Finally, the HandCorpus website is cross-platform, cross-browser and fully accessible through all kind of mobile-devices.

Title: Leveraging Big Data for Grasp Planning
Abstract:
We publicly released a new large-scale database containing grasps that are applied to a large set of objects from numerous categories. These grasps are generated in simulation and are annotated with the standard epsilon and a new physics-metric. We use a descriptive and efficient representation of the local object shape at which the grasp is applied. Each grasp is annotated with the proposed metrics and representation.
Given this data, we present a two-fold analysis:
(i) We use crowdsourcing to analyze the correlation of the two metrics with grasp success as predicted by humans. The results confirm that the proposed physics metric is a more consistent predictor for grasp success than the epsilon metric. Furthermore it supports the hypothesis that human labels are not required for good ground truth grasp data. Instead the physics metric can be used for simulation data.
(ii) We apply big-data learning techniques (Convolutional Neural Networks and Random Forests) to show how they can leverage the large-scale database for improved prediction of grasp success.

Title: The KIT Whole-Body Human Motion Database
Abstract:
We present a publically released large-scale whole-body human motion database consisting of motion data of the observed human subject as well as the objects with which the subject is interacting. We describe the procedures for a systematic recording of human motion data with associated complementary data like video recordings and additional sensor measurements (force, IMU, …), as well as environmental elements and objects. The availability of accurate object trajectories together with the associated object mesh models makes the data especially useful for the analysis of manipulation, locomotion and loco-manipulation tasks. We present procedures and techniques for motion capturing, annotating and organization in large-scale databases as well as for the normalization of human motion to a unified representation based on a reference model of the human body. In addition, we provide methods and software tools for efficient search in the database as well as the transfer of subject-specific motions to robots with different embodiments and discuss several current applications of the database in our current research on whole-body grasping and loco-manipulation

Title: Datasets (and tools) from disconnected markers to organized behaviors: a path towards autonomous manipulation
Abstract:
In this talk, I will discuss the pros and cons in generating large datasets for grasping in experimental settings or in simulated environments, possibly including the use of optimal control methods to substitute the human in the loop.

Title: Dexterity Network (Dex-Net): A Cloud-Based Network of 3D Objects for
Robust Grasp Planning
Abstract:
Dexterity Network 1.0 (Dex-Net) is a data-driven approach to robust
robot grasping and manipulation based on a new dataset of 3D object
models that currently includes over 10,000 unique 3D object models and
2.5 million parallel-jaw grasps. Dex-Net includes a Multi-Armed
Bandit algorithm with correlated rewards from prior grasps to estimate
the probability of force closure under sampled uncertainty in object
and gripper pose and friction. Dex-Net 1.0 uses Multi-View
Convolutional Neural Networks (MV-CNNs), a new deep learning method
for 3D object classification, as a similarity metric between objects.
Dex-Net 1.0 runs on the Google Cloud Platform to simultaneously run up
to 1,500 virtual cores, reducing runtime by three orders of magnitude.
Experiments suggest that using prior data can significantly benefit
the quality and complexity of robust grasp planning.
