چکیده

This paper addresses the problem of bi-manual object handover with a humanoid robot, i.e. the task of passing objects from one hand to the other. Bi-manual coordination is fundamental for improving manipulation capabilities of humanoid robots. We propose a novel and effective pipeline that tackles the problem by using visual and tactile feedback to localize the object and maintain grasp stability during the task. Given the object in one of the robot hand (first hand), the object in-hand pose is estimated by a localization algorithm, which makes use of vision and tactile information. Then, the estimated pose is used to automatically choose a suitable pose for the second hand among a set of candidates, a-priori annotated on the object model. The selected pose is finally used to accomplish the handover task. The performance of our approach is assessed on a real robotic system, the iCub humanoid robot, on a set of objects from the YCB dataset. Experiments demonstrate that the proposed method allows performing proper and reliable handovers with different every-day objects.

Internal models for bi-manual tasks.

Co-ordinated bi-manual actions form the basis for many everyday motor skills. In this review, the internal model approach to the problem of bi-manual co-ordination is presented. Bi-manual coordinative tasks are often regarded as a hallmark of complex action. They are often associated with object manipulation, whether the holding of a single object between the two hands or holding an object in e...

Spatiotemporal Movement Planning and Rapid Adaptation for Manual Interaction

Many everyday tasks require the ability of two or more individuals to coordinate their actions with others to increase efficiency. Such an increase in efficiency can often be observed even after only very few trials. Previous work suggests that such behavioral adaptation can be explained within a probabilistic framework that integrates sensory input and prior experience. Even though higher cogn...

Pipeline upheaval buckling in clayey backfill using numerical analysis

Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...

Learning Complex Manipulation Tasks from Heterogeneous and Unstructured Demonstrations

Motivated by the current state-of-the-art in Robot Learning from Demonstration (LfD), in this paper, we tackle two central issues in the learning pipeline: namely, dealing with (1) heterogeneity and (2) unstructuredness in demonstrations of complex manipulation tasks. We build upon our previous work on transform-invariant segmentation and action discovery [1], to learn the underlying action seq...
