Unfolding of a rectangular cloth from unarranged starting shapes by a Dual-Armed robot with a mechanism for managing recognition error and uncertainty
Advanced Robotics, Vol.31, Issue 10, pp. 544 – 556,,31(10):544-556 2017(Feb. 09)
Author:Hiroyuki Yuba, Solvi Arnold, Kimitoshi Yamazaki
Abstract:We propose a method for unfolding a rectangular cloth placed on a table in an arbitrary unarranged shape, using a dual arm robot. There are many situations where the manipulation of fabric products by dual arm robots is slow due to operation complexity. Also, observation of fabric products in unarranged shapes can be fraught with uncertainty, posing further difficulties for robotic manipulation. In this article, we address these problems for our specific task, implementing a ‘pinch and slide motion’ to address the former issue, and an operation selection mechanism implemented as a partially observable Markov decision process to address the latter. We used this approach to let a robot unfold a rectangular cloth, thereby experimentally verifying the effectiveness of our approach.
Keywords:Cloth unfolding, dual-armed manipulation, pinch and slide motion

Real-time scene parsing by means of a convolutional neural network for mobile robots in disaster scenarios
IEEE International Conference on Information and Automation , :201-207 2017(Jul. 18)
Author:Solvi Arnold, Kimitoshi Yamazaki
Abstract:Disaster robotics poses particular challenges for computer vision, both in terms of image characteristics (due to motion blur, difficult light conditions, lack of up/down orientation, etc.), and in terms of learning data (limited availability, difficulty of annotation due to image quality, etc.). We developed a system for real-time scene-parsing, intended for use in a support system for operators of remote-controlled mobile robots employed in disaster areas. Our testbed is video footage gathered by a snake-like mobile robot exploring an (artificial) collapsed building environment. The core of the system is a relatively small-scale convolutional neural network. Our approach combines pixel-level learning with superpixel-level classification, in an effort to learn efficiently from a relatively small number of partially annotated frames. Our classification system is capable of real-time operation, and demonstrates that convolutional neural networks can be applied effectively even under the harsh conditions imposed by disaster robotics
