Download or read book Tactile Sensing Information and Feedback via Wave Propagation written by Yitian Shao and published by Springer Nature. This book was released on 2022-02-24 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: A longstanding goal of haptic engineering is to develop haptic interfaces that can provide realistic sensations of touch. A fundamental step towards this goal is to understand what mechanical tactile signals the hand feels during daily touch interactions. This book reveals the complex patterns of mechanical waves propagating throughout the hand that can be elicited even by simple touch interactions, which helps in expanding existing knowledge of tactile function beyond the region of near skin-object contact and inspires new designs for haptic sensing and feedback technologies. The first part of this book describes new methods for capturing dynamic, spatially distributed tactile signals in the whole hand during natural hand interactions. The second part characterizes these signals and evaluates how well and how efficiently they encode the information of touch, relating to the transmission of mechanical waves in hand tissues. The final part demonstrates how these findings can be utilized to create novel haptic effects and tactile displays. Tactile Sensing, Information, and Feedback via Wave Propagation provides a unique view of tactile sensing and feedback and will appeal to researchers, engineers, and students who are interested in learning cutting-edge haptic science and technology.
Download or read book Cutaneous Haptic Feedback in Robotic Teleoperation written by Claudio Pacchierotti and published by Springer. This book was released on 2015-11-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work addresses the challenge of providing effective cutaneous haptic feedback in robotic teleoperation, with the objective of achieving the highest degree of transparency whilst guaranteeing the stability of the considered systems. On the one hand, it evaluates teleoperation systems that provide only cutaneous cues to the operator, thus guaranteeing the highest degree of safety. This cutaneous-only approach shows intermediate performance between no force feedback and full haptic feedback provided by a grounded haptic interface, and it is best suitable for those scenarios where the safety of the system is paramount, e.g., robotic surgery. On the other hand, in order to achieve a higher level of performance, this work also investigates novel robotic teleoperation systems with force reflection able to provide mixed cutaneous and kinesthetic cues to the operator. Cutaneous cues can compensate for the temporary reduction of kinesthetic feedback necessary to satisfy certain stability conditions. This state-of-the-art volume is oriented toward researchers, educators, and students who are interested in force feedback techniques for robotic teleoperation, cutaneous device design, cutaneous rendering methods and perception studies, as well as readers from different disciplines who are interested in applying cutaneous haptic technologies and methods to their field of interest.

Download or read book Robotic Touch for Contact Perception written by Lin, Xi and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tactile perception subserves the impressive dexterity found in humans but also found in their robotic counterparts. Recently, a new wave of tactile sensors relying on off-the-shelf cameras, provide a dense tactile image of the contact. However, by the way these sensors operate, the link between the mechanics of the skin and the tactile images is not evident. In this thesis, we present a novel camera-based tactile sensor, named ChromaTouch, which captures physically-driven dense images of the three-dimensional interaction that happens at the interface between the artificial skin and the touched object. The sensor measures the strain field induced by the contact, by imaging the pattern and color change of two overlapping markers array, one translucent and yellow and the other opaque and magenta. The motif seen by the camera is a bijective function of the relative motion of the markers allowing a reconstruction of the stress and strain field at the interface. The sensor, boasting up to 441 sensing elements, shows high robustness to external luminosity and camera resolution, and it is able to estimate the local coefficient of friction of the contact surface with one simple press. A hemispherical version extended the results to arbitrary shapes and is able to estimate the local curvature via a simple press using Hertz contact theory. Sensing the dense 3d deformation field at the contact opens the doors to a comprehensive, physically-based measurement of the interaction. Improved artificial perception of the object and of the interaction can inform robotic exploration, dexterous grasping and manipulation.
Download or read book Design and Perception of Wearable Multi contact Haptic Devices for Social Communication written by Cara Mae Nunez and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During social interactions, people use auditory, visual, and haptic (touch) cues to convey their thoughts, emotions, and intentions. Current technology allows humans to convey high-quality visual and auditory information but has limited ability to convey haptic expressions remotely. As people interact more through digital means rather than in person, it becomes important to have a way to be able to effectively communicate emotions remotely through touch as well. Systems that convey haptic signals could allow for improved distant socializing and empathetic remote human-human interaction. Due to hardware constraints and limitations in our knowledge regarding human haptic perception, it is difficult to create haptic devices that completely capture the complexity of human touch. This dissertation presents novel methods for the design and control of wearable multi-contact haptic devices, explores human haptic perception with these devices, and highlights how these devices can be used for various forms of social communication. First, we present the design, modeling, and control of two devices that use actuation of discrete contact points to create the illusion of a continuous and pleasant stroking sensation on the arm similar to what is felt during calming and comforting touch between humans. User studies validated that control parameters creating apparent motion with speeds that stimulate the specific touch receptors embedded in the skin which selectively respond to stroking create the most continuous and pleasant tactile stroking sensations. We also present two user studies: one which confirms the realism of the sensation applied and its similarity to human-human social touch and another that explores the effect of spacing between discrete contact points on the illusion of a continuous, pleasant stroking sensation. Second, we explore human haptic perception of touch cues on the forearm. We present a user study in which we directly compare the continuity and pleasantness of the stroking sensation generated via the devices described in the previous chapter and investigate how many contact points are necessary to create the illusion of tactile stroking. We find that you can create the illusion of a continuous and pleasant stroking sensation with as few as four discrete contact points. We also introduce a data-driven method for generating haptic signals that can communicate emotions. We present a user study in which we collected human-human touch data from couples and close friends communicating emotions through touch to the forearm in order to create a naturalistic social touch dataset. We use the touch data to produce haptic signals and validate that the signals can successfully communicate emotions with a multi-contact wearable haptic device. Last, we present the design and control of novel haptic devices that display normal skin deformation to the human back (dorsum) using arrays of soft pneumatic actuators. We targeted our haptic feedback to the back as it is a contact location during hugging interactions that is socially acceptable to test. We introduce the concept of macro-mini pneumatic actuation and how it can be used in wearable devices to help conform the device to the user's body and provide more salient haptic stimuli. A user study validated that participants have lower detection thresholds and can better localize the provided stimuli from macro-mini pouch actuators compared to a more traditional single pneumatic actuator. We discuss how the soft haptic vest containing the array of macro-mini actuators and the results from the user study can be used to replicate human-human hugging interactions. This dissertation presents new designs and control schemes for wearable multi-contact haptic devices for social communication and key insights regarding human haptic perception. The findings and technologies presented in this thesis could serve a variety of applications including social haptic devices for touch therapy, mediated social touch, and teleoperated social-physical human-robot interaction.

Download or read book Haptic Perception Decision making and Learning for Manipulation with Artificial Hands written by Randall Blake Hellman and published by . This book was released on 2016 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robotic systems are outmatched by the abilities of the human hand to perceive and manipulate the world. Human hands are able to physically interact with the world to perceive, learn, and act to accomplish tasks. Limitations of robotic systems to interact with and manipulate the world diminish their usefulness. In order to advance robot end effectors, specifically artificial hands, rich multimodal tactile sensing is needed. In this work, a multi-articulating, anthropomorphic robot testbed was developed for investigating tactile sensory stimuli during finger-object interactions. The artificial finger is controlled by a tendon-driven remote actuation system that allows for modular control of any tendon-driven end effector and capabilities for both speed and strength. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. Next, attention was focused on real-time artificial perception for decision-making. A robotic system needs to perceive its environment in order to make decisions. Specific actions such as "exploratory procedures" can be employed to classify and characterize object features. Prior work on offline perception was extended to develop an anytime predictive model that returns the probability of having touched a specific feature of an object based on minimally processed sensor data. Developing models for anytime classification of features facilitates real-time action-perception loops. Finally, by combining real-time action-perception with reinforcement learning, a policy was learned to complete a functional contour-following task: closing a deformable ziplock bag. The approach relies only on proprioceptive and localized tactile data. A Contextual Multi-Armed Bandit (C-MAB) reinforcement learning algorithm was implemented to maximize cumulative rewards within a finite time period by balancing exploration versus exploitation of the action space. Performance of the C-MAB learner was compared to a benchmark Q-learner that eventually returns the optimal policy. To assess robustness and generalizability, the learned policy was tested on variations of the original contour-following task. The work presented contributes to the full range of tools necessary to advance the abilities of artificial hands with respect to dexterity, perception, decision-making, and learning.

Available in PDF, EPUB and Kindle. Book excerpt: Future robots are expected to work closely and interact safely with real-world objects and humans alike. Sense of touch is important in this context, as it helps estimate properties such as shape, texture, hardness, material type and many more; provides action related information, such as slip detection; and helps carrying out actions such as rolling an object between fingers without dropping it. This book presents an in-depth description of the solutions available for gathering tactile data, obtaining aforementioned tactile information from the data and effectively using the same in various robotic tasks. The efforts during last four decades or so have yielded a wide spectrum of tactile sensing technologies and engineered solutions for both intrinsic and extrinsic touch sensors. Nowadays, new materials and structures are being explored for obtaining robotic skin with physical features like bendable, conformable, and stretchable. Such features are important for covering various body parts of robots or 3D surfaces. Nonetheless, there exist many more hardware, software and application related issues that must be considered to make tactile sensing an effective component of future robotic platforms. This book presents an in-depth analysis of various system related issues and presents the trade-offs one may face while developing an effective tactile sensing system. For this purpose, human touch sensing has also been explored. The design hints coming out of the investigations into human sense of touch can be useful in improving the effectiveness of tactile sensory modality in robotics and other machines. Better integration of tactile sensors on a robot’s body is prerequisite for the effective utilization of tactile data. The concept of semiconductor devices based sensors is an interesting one, as it allows compact and fast tactile sensing systems with capabilities such as human-like spatio-temporal resolution. This book presents a comprehensive description of semiconductor devices based tactile sensing. In particular, novel Piezo Oxide Semiconductor Field Effect Transistor (POSFET) based approach for high resolution tactile sensing has been discussed in detail. Finally, the extension of semiconductors devices based sensors concept to large and flexile areas has been discussed for obtaining robotic or electronic skin. With its multidisciplinary scope, this book is suitable for graduate students and researchers coming from diverse areas such robotics (bio-robots, humanoids, rehabilitation etc.), applied materials, humans touch sensing, electronics, microsystems, and instrumentation. To better explain the concepts the text is supported by large number of figures.

Download or read book Tactile Perception Haptic Exploration and Map Rendering for Robots that Operate Within Granular Materials written by Jia Shengxin and published by . This book was released on 2022 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robots are expected to operate autonomously in unstructured, real-world environments. For effective physical interaction with the world, robots must build and refine their understanding of the environment through sensory feedback. However, tactile feedback has been used primarily in open-air environments and not within granular materials. When robots operate within opaque granular materials, tactile and proprioceptive feedback can be more informative than visual feedback. Our long-term objective is to leverage tactile sensors to develop efficient algorithms that enable robots to infer environmental conditions and to plan exploratory movements that reduce uncertainty in their models of the world. Motivated by the need to keep humans out of harm's way in search and rescue or other field environments, we address the challenge of using tactile feedback to locate objects buried in granular materials. In study \#1, we designed a tactile perception pipeline for sensorized robot fingertips that directly interact with granular materials in teleoperated systems. We proposed an architecture called the Sparse-Fusion Recurrent Neural Network (SF-RNN) to detect contact with an object buried within granular materials. We leveraged multimodal tactile sensor data in order to classify contact states within five different granular materials. We also constructed a belief map that combines probabilistic contact state estimates and fingertip location. In study \#2, we developed a framework for tactile perception, mapping, and haptic exploration for the autonomous localization of objects buried in granular materials. The haptic exploration task was performed within densely packed sand mixtures using sensor models that account for granular material characteristics and aid in the interpretation of interaction forces between the robot and its environment. The haptic exploration strategy was designed to efficiently locate and refine the outline of a buried object while simultaneously minimizing potentially damaging physical interactions with the object. Continuous occupancy maps were generated that fused local, sparse tactile information into global maps. In summary, we developed tactile-based frameworks for perception, planning, and mapping for the challenging task of localizing objects buried within granular materials. Our work can serve as a foundation for more complex, autonomous robotic behaviors such as the excavation and bimanual retrieval of fragile, buried objects.

Book excerpt: This Open Access book offers an original interdisciplinary overview of the role of haptic feedback in musical interaction. Divided into two parts, part I examines the tactile aspects of music performance and perception, discussing how they affect user experience and performance in terms of usability, functionality and perceived quality of musical instruments. Part II presents engineering, computational, and design approaches and guidelines that have been applied to render and exploit haptic feedback in digital musical interfaces. Musical Haptics introduces an emerging field that brings together engineering, human-computer interaction, applied psychology, musical aesthetics, and music performance. The latter, defined as the complex system of sensory-motor interactions between musicians and their instruments, presents a well-defined framework in which to study basic psychophysical, perceptual, and biomechanical aspects of touch, all of which will inform the design of haptic musical interfaces. Tactile and proprioceptive cues enable embodied interaction and inform sophisticated control strategies that allow skilled musicians to achieve high performance and expressivity. The use of haptic feedback in digital musical interfaces is expected to enhance user experience and performance, improve accessibility for disabled persons, and provide an effective means for musical tuition and guidance.
