This tactile sensor comprises two piezoelectric materials. In addition, the sensitivity of the sensor has been optimized by controlling sputtering parameters including oxygen flow rate and film thickness of the ITO piezoresistive layer. Artiï¬cial tactile sensors in robotic applications are rep-resented by pressure proï¬le sensing arrays, force-torque sensors, and dynamic tactile sensors [9]. The preliminary experimental results show that the developed system can achieve a success rate of about 95% in the wire insertion and connection task. Starting from the observation of soft-fingered grasping and manipulation, the book provides a parallel distributed model that takes into account tangential deformation of the fingertips. Since the sensor adopts a single-layer composite structure, the sensor is durable with respect to external force. Experiments with a new force/tactile sensor equipping the gripper of a mobile manipulator show that the approach allows the robot to successfully perform manipulation tasks unfeasible with a standard fixed grasp. In this paper we present a scalable design model of artificial fingers, which combines mechanical design and embedded electronics with a sophisticated multi-modal sensor system consisting of sensors for sensing normal and shear force, distance, acceleration, temperature, and joint angles. (2000). Proceedings of the IEEE International Conference on Micro Electro Mechanical Systems (MEMS). Results are presented showing the output generated by the sensor array for different object shapes as well as sensitivity and linearity plots.. A proposed gripper design for use with the tactile sensor array is also presented. We wish to unite the two paradigms with a haptic sensor as versatile as the sense of touch and developed for a dual purpose: to improve the robotic capability to interact with the physical world, and to improve the human capability to interact with the virtual world for emerging applications with a heightened sense of presence. A new type of tactile sensor using pressure-conductive rubber with stitched electrical wires is presented. Moreover, the precision requested during the assembly task and the typical crowded space inside the switchgear imply, on one side, the development of specific hardware and software tools and, on the other side, high adaptability and flexibility of the robotic system. Likewise, tactile sensing will become essential for robotic and prosthetic gripping performance as applications move toward unstructured environments. The mechanical structure of the sensor has been optimized in terms of geometry and material physical properties to provide the sensor with different capabilities. The sensor is suitably designed to provide the robotic grasping device with a sensory ⦠v.22, n.2, 2004, p.213-221, Initial experiments characterizing a shunt-mode sensor that The combination can be used in robotics, telecheric applications, biomechanics and virtual reality applications. One end of the sensor incorporates three orthogonal reflective planes. Force/tactile feedback, the only perception source used by the algorithms, is suitably exploited not only for safe grasping of a variety of objects with uncertain weight and inertial properties, but also for in-hand manipulation actions, like object pivoting or gripper pivoting. The sensor with 7Ã7 matrix elements was tested for its sensitivity to different extents of applied force/pressure. The method is capable of assembling various and complex 3D structures from 2D counterparts. this paper reviews the state of tactile sensing in robotics. The article also includes an overview of different types of robot applications and the types of tactile information that they employ. The development of a tactile sensor based on optical fiber specklegram analysis is reported. This covers the context-independent phases of the collision event pipeline for robots interacting with the environment, as in physical humanârobot interaction or manipulation tasks. We present a new robust nonlinear tracking control law that guarantees global exponential convergence of the, This study details the development of a high performance servo-hydraulic actuator for a Selective Compliant Assembly Robotic Arm (SCARA). This paper reports the development of a manipulation system for electric wires, implemented by means of a commercial gripper installed on an industrial manipulator and equipped with cameras and suitably designed tactile sensors. The proposed algorithm is further integrated into a contact force visualization module as well as a closed-loop adaptive grasp force control framework and is shown to be useful in both visualization of contact stability and minimum force grasping task. An external force applied to the deformable layer produced local variations of the bottom surface of the elastic material, and the couples of optical devices measured the vertical deformations in a discrete number of points. The construction and the electronic circuit are also described. For robotic applications, the two main research areas on tactile sensor development are related with object con- trolled lifting and grasping tasks and with the ability to characterize different surface ⦠Combined with functional materials, these 3D structures have shown spatially resolved functions, including omnidirectional tactile sensing and spatial temperature sensing. respectively. ... An ADC (Analog-to-Digital Converter) Module converts the analog signals (sounds), captured by the Hydrophones, is converted into digital signals, which are then transmitted to a station via the RF (Radio Frequency) Antenna on the Float Platform. The sensor characterization indicated a 0.5 Nâ»Â¹ sensitivity, with capability to detect variations of 1 mm in force location, being comparable to the requirements for tactile technologies. Robotica. Such feature requires the capability to control the grasping force, which requires proper measurement of contact forces and moments as well as contact locations. Despite this, the design method here presented allows to adapt the sensor to a large set of robotic applications, thanks to its simplicity in the construction and low cost. An analytic model of the compliant frame deformation is proposed and verified both by finite element analysis and by experimental measures performed on four different sensor specimens manufactured by 3D printing and CNC milling, and the results have been compared. Currently, the design of Hall-effect-based tactile sensors to perform such tasks is based on trial and error. it was mounted on the end of a robotic manipulator which rubbed flat specimens such as brass plates with step-heights of δ=0.05, 0.1, 0.2 mm and a brass plate with no step-height. Distributed proximity sensors were adopted to locally modify the planned trajectory when unexpected or misplaced obstacles intervene in the scene. We use supervised learning to localize probe position and direction with classification accuracies of 96% and 89% respectively. The designed structures are implemented in a commercial CMOS process with a small number of post-micromachining steps. The paper describes the detailed design and the prototype characterization of a novel tactile sensor1 for robotic applications. profile with roughness. Tactile Sensors and their Robotic Applications Mentor : Prof. Himanshu Patel Prepared by : Aasheesh Tandon(12BIC044) Paxaj ⦠New applications for tactile sensing including surgery, rehabilitation and service robotics, and food processing automation show considerable potential and are now receiving significant levels of research attention. Concerning to that, this paper deals with the original solutions adopted for, One of the main control challenges of National Aeronautics and Space Administrationâs proposed Asteroid Redirect Mission (ARM) is to stabilize and control the attitude of the spacecraft-asteroid combination in the presence of large uncertainty in the physical model of a captured asteroid. The force sensor presents a linear response and a resolution of 0.38 N and a sensitivity of 0.05 V/N. The designed MP-M dynamometer model is capable to measure spatial force/moment accurately and simulation experiments are discussed. The first three axis force sensing They have beendesigned and implemented in the fingers of the humanoid robotObrero. He published more than 30 international journal and conference papers and he is co-author of the book “Active Control of Flexible Structures”, published by Springer. An analytic model of the compliant frame deformation is proposed and verified both by finite element analysis and by experimental measures performed on four different sensor specimens manufactured by 3D printing and CNC milling, and the results have been compared. The resulting sensor is cheap, accurate and a simple signal processing sensor. This work deals the design and implementation of an intrinsic tactile sensing system based on a set of 3-axis force MEMs sensors and the detection of slippage with such system. Comparable performance is not feasible with contemporary electrical actuators of similar size. The regrasp control policy improves the success rate of grasp actions by an average relative increase of 70% on a test set of 8 objects. design and construction of an axial-flux permanent magnet machine (AFPM) prototype rated 8000 N-m, 682 rev/min. The second involves contact pressure sensing, i.e., estimating surface normal and shear stress ⦠This type of perception information is of paramount importance not only in dexterous manipulation but even in simple grasping tasks, especially when objects are fragile, such that only a minimum amount of grasping force can be applied to hold the object without damaging it. By measuring a surface traction field, the GelForce tactile sensor can represent the magnitude and direction of force applied to the skin's surface using computer vision. The classification method consists of applying multiscale principal components analysis prior to the classification with a multilayer neural network. The output fiber speckle fields, produced by coherent light transmission through the multimode waveguides, are processed for evaluation of the normalized inner-product coefficients, being further correlated to the external load characteristics according to a specklegram referencing approach. actuator is subsequently designed, manufactured and experimentally evaluated. Packaging-induced performance changes of microelectromechanical systems (MEMS) usually are detrimental in the device development. The design objective is the development of a sensor able to estimate both position and orientation of the grasped wire, with respect to a known reference frame. the normal and shear components of the force vector. Moreover, when a quartz wafer [15] is packaged as a mono-axial piezoelectric sensor or tri-axial load sensor [16]- [12] as shown in Figure 2. We first introduce the observation of the contact deformation patterns of hyperelastic materials under ideal single-axial loads in simulation. The tactile module comprises a nine Degree of Freedom Microelectromechanical Magnetic, Angular Rate, and Gravity system (9-DOF MEMS MARG) and a deep MEMS pressure sensor embedded in a compliant structure that mimics the function and the organization of mechanoreceptors in human skin as well as the hardness of the human skin. A nonlinear Hammerstein-Winer model is proposed to characterize the linear and nonlinear behavior of the sensor. Fiber optic sensors are expensive and difficult to integrate in tactile modules due to the bending losses in the fiber routing. These issues, which are strongly affecting the design flow, are discussed together with measurement results of the fabricated structures. In order to create a tactile system the 3-axis force sensors are protected by a coating, a study about the coating is made. During manipulation, the hand partially occludes the object from sight. The problem is addressed for rigid robots first and then extended to the presence of joint/transmission flexibility. simultaneously measures both normal and shear strains due to an applied A silicon-based flexible tactile sensor for ubiquitous robot companion applications Kunnyun Kim 2, Kang Ryeol Lee1,2, Dae Sung Lee , Nam-Kyu Cho , Won Hyo Kim 2, Kwang-Bum Park , Hyo-Derk ⦠The data are however not limited to individual contacts and can be used to extract a wide range of information about the objects in the environment as well as the actions of the robot during the interactions.

Moreover, the aluminium release etch can be achieved with a simpler etch-opening formation procedure than the oxide release etch.

The optoelectronic components were organized in a matrix structure. His research interests include robust control, control of mechanical systems, industrial and advanced robotics, control of aerospace and aeronautical systems, active noise and vibration control of flexible structures. The design, modeling, and testing of a flexible tactile sensor and its applications are presented. A tactile sensor with MEMS structure has been presented for robotic application by Mei et al. The tactile sensor has been interfaced to computer for the convenience of automatic scanning and making it more user interactive. ⦠To reduce the interference among the sensing points, we also propose a structure where the grooves are inserted between the adjacent electrodes. We propose a new tactile sensor utilizing piezoelectric vibration. Both methods have their strengths, but also limitations. Figures 3 and 4 show a miniature force/tactile sensor design that can measure distributed contacts and estimate contact force and torsional moments. The proposed approach allows to reconstruct the wire end point with a precision sufficient to allow the robot correctly execute the insertion phase with a high success rate. ?sense of touch?? Here, we describe the sensor design, its characterization, and data analysis. The bioelectronic skin devices sensitively detect chemical coldâpain stimuli like cinnamaldehyde at 10 fm, and selectively discriminate cinnamaldehyde among other chemical stimuli. These issues are pointed out by many reviews of tactile sensors [10], [11], [12], and many new tactile sensors focus on these issues as priorities. The sensor's single cell consists of a columnar feeler and 2-by-2 conical feelers. The concept of such a software tool is here presented. Moreover, because the substrate on which the modules are mounted is sufficiently pliable to be folded and stiff enough to be cut, it is possible to freely distribute the individual tactile elements. The main advantages of the proposed sensor consist in the use of a very compact commercial optoelectronic component, called light fork, as sensing element. Euopean patent pending, Application no. Then, the model was imported into Isight, with the maximisation of magnet displacement as the objective function. resistance between a specially treated polyimide film and a resistive The measuring range of six-axis force/torque sensors is very wide [17] and sensors survive high overload is more than 100 percent of full-scale output. Manipulation planning and control are relevant building blocks of a robotic system and their tight integration is a key factor to improve robot autonomy and allows robots to perform manipulation tasks of increasing complexity, such as those needed in the in-store logistics domain. The FEM simulations results are approximately 99-100% of the exerted axial force, vertical force and pitch moment respectively. This paper presents a data glove equipped with a force sensor. Additionally, a computer vision system able to recognize the location of the wires and of the electromechanical components inside the switchgear has been developed. The plate is attached on the thumb.

Tactile sensor based on pressure change measurement is simple and cheap solution when magnitude of force is required. Finally, various system issues that keep tactile sensing away from widespread utility are discussed. To deal with the wire deformability and occlusion problems during the wire insertion, machine learning and sensor fusion techniques have been adopted to enable the wire manipulation by means of tactile sensors and 2D cameras feedback. Finally we end the article with a discussion for future tactile applications which are still beyond the current capabilities of robots. Moreover, the sensor specimens calibration and the experimental validation have been performed both in static and dynamic conditions. It is well known that the anatomy of our fingers, which consists of soft fingertips and hard fingernails, is well designed for grasping and manipulating objects. Driven by the compressive buckling force, the 2Dâformed membrane materials, which are preâdefined and selectively bonded to the substrates, are then assembled to 3D structures. Finally, the magnitude and location of the forces applied over the tactile frame are estimated by means of a data fusion technique, yielding the probabilistic distribution of the mechanical disturbances. Tactile sensing enables measurements to be obtained in areas that are inaccessi⦠The paper described the detailed design and the experimental characterization of a novel tactile sensor for robotic applications based on optoelectronic technology. One of the challenges is the implementation of the wire insertion task, i.e., a wire, grasped by a robot, has to be inserted into the hole of a switchgear component to be then tightened. This experiment aims to automatize the switchgear wiring process by using industrial manipulators and properly designed hardware and software tools. Grasping and manipulation with anthropomorphic robotic and prosthetic hands presents a scientific challenge regarding mechanical design, sensor system, and control. The sensor is based on a two-layer structure, i.e. Therefore, the estimated value inherently has a large numerical error, which is an obstacle for precise on-line estimation of the disturbance. As expected, in the linear setup, the magnitude spectrum of the sensorsâ output shows that the module can detect the applied stimuli with frequencies ranging from3.66 Hz to 11.54 Hz with an overall maximum error of±0.1 Hz. Furthermore, the effect of cold environments is evaluated on the responses of nociceptive ion channels, resulting in the sensitive responses to cinnamaldehyde at lower temperatures than at high temperatures. EP11425148.1. The mathematical model to calculate the force from the measurements is fully detailed.

IEEE/RSJ International Conference on Intelligent Robots and Systems. In the presence of modeling errors and disturbances, this control law is finite-gain L_p stable and input-to-state stable. However, the large variation in their stress properties together with limited available pitch rendered them inferior to membranes from sacrificial aluminium etching. Kasap. The results suggest that the hand can effectively enhance the functionality of a robotic surgical system and overcome the limits on force sensing introduced by the use of robots in laparoscopic surgery. Underactuated finger design enhances the adaptivity in grasping and the compliance in interaction with the environment. This activity comprises results from a series of projects including the European funded ones MESA and MESEMA. The sensor is thin and flexible and can cover three-dimensional objects. This structure is implemented during the molding process, which is adopted to extend the porous tactile sensor to large-scale and facile fabrication. The ultimate aim is to identify device and system parameters and configurations and to match these as far as possible with applications. We found that increased emphasis on understanding tactile sensing and perception issues has opened up potential for new application areas. The model is supported with many experimental verifications and simulation results. However, an integration of reactive grasping control and motion planning can allow robots to perform such tasks even with grippers with limited dexterity. The central components of this sensor are three coils and a dielectric medium. The sensor was based on the use of light-emitting diode (LED) phototransistor couples and a silicone rubber layer positioned above the optoelectronics devices. Further, the bioelectronic skin is used to evaluate the effect of cold environments on the response of the hTRPA1, finding that the nociceptive ion channel responds more sensitively to cinnamaldehyde at lower temperatures than at higher temperatures. Figure 1 is the section view of unstressed state of friction tactile sensor⦠This paper describes the design, manufacture and properties of membrane structures with capacitive detection of deflection. A bioelectronic skin device based on nociceptive ion channels in nanovesicles is developed for the detection of chemical coldâpain stimuli and cold environments just like human somesthetic sensory systems. First, we construct a tactile-based grasp quality metric using a deep convolutional neural network trained on over 2800 grasps. The combination can be used in robotics, telecheric applications, biomechanics and virtual reality applications. Università degli Studi della Campania "Luigi Vanvitelli". In the bioelectronic skin, the nanovesicles containing the hTRPA1 nociceptive ion channel protein reacts to coldâpain stimuli, and it is electrically monitored through carbon nanotube transistor devices based on floating electrodes. On the basis of the unique structure of the sensor and ingenious measuring methods, the authors realized the purpose to test more than one quantity, that is, the perpendicular force component, the magnitude and direction of the horizontal force component, with a single sensor. Moreover, the demonstrated 3D bifunctional sensors based on laser induced graphene show capability of spatially resolved tactile sensing and temperature sensing. Robots are expected to recognize the properties of objects in order to handle them safely and efficiently in a variety of applications, such as health and elder care, manufacturing, or high-risk environments. force, and the minimum dashpot coefficient (B), defined as the ratio of frictional force to rolling velocity, were extracted to be 0.02 and 4 x 10-2 kg/s , respectively, for the linear device. Sensors must be able to detect forces across the fingers of the prosthesis in a repeatable and reliable fashion. This effect is pronounced as the limiting extensibility decreases to less than 5 and eliminates the one-to-one mapping of hardness to modulus. Therefore, the perception of torsional moments is a key requirement of the designed sensor. He was associate professor of Automatic Control at the University of Naples “Federico II”. The tactile sensor of De Maria et al. The resulting design model allows deriving freely scalable and multimodally sensorised fingers for robotic and prosthetic hands. It is a challenging task to obtain contact information and object orientation using tactile sensors during grasping. Upon the application of the force, the distance between the planes and the fiber tips changes, thus, the LTV voltage changes, enabling the simultaneous measurement of forces along three normal axes utilizing only one set of force measurement unit. Moreover, the data fusion approach provided the estimation of the load distribution with 0.86 relative accuracy, allowing the assessment of tactile variables based on the response of only 3 sensing fibers and without utilizing wavelength multiplexing schemes. Academic Press, New York, 1978. Two different intrinsic systems based on an array of 3-axis force sensors are developed, the first one is used a feasibility test of this kind of system. The sensor is based on a two-layer structure, i.e. Concerning this field of research he is responsible of National and European research contracts.
