Tendon actuated exploratory finger with polymeric skin-like tactile sensor. workcell has been assembled to investigate touch-mediated grasping and These sensors provide a rich and diverse set of data signals that contain detailed information collected from contacts between the robot and its environment. The result is a first step in a trajectory toward associative visual-haptic categories that bounds the incremental complexity of each stage of development. The article also includes an overview of different types of robot applications and the types of tactile information that they employ. Tactile sensing is a key sensor modality for robots interacting with their surroundings. used to compute the point of contact [18]. Robots will find much wider application when tactile sensors currently being developed are put to use. Minimal access surgery (MAS), also known as keyhole surgery, offers many advantages over the more traditional open surgery. However, unlike the senses of vision and audition which have standardized data format, the format for tactile data is vastly dictated by the sensor manufacturer, which makes it difficult for large-scale learning on data collected from heterogeneous sensors, limiting the usefulness of publicly available tactile datasets. Advantages and disadvantages of the most common sensor, sors widely available today. In: IEEE International Conference on Manipulation and Grasping IMG. However, it possesses one very significant drawback––the loss, by the surgeon, of the “sense of feel” that is used routinely in open surgery to explore tissue and organs within the operative site. This service is more advanced with JavaScript available, The World Yearbook of Robotics Research and Development Tactile Sensor is a device specifying an object’s contact. We discuss different types of information that can be extracted at each level of the hierarchy. GelSight can generate detailed 3-D maps of an object's surface and detect some of its characteristics. profile information for experiments involving object manipulation and primarily the fingertips are used for contact. Information acquired from artificial sensing systems can be used for finding contact locations, reconstructing and recognizing object shape, and measuring contact forces and temperature. Partly because we can use it as benchmark, partly, because the human sensory system and manipulation ca-, pacity is both a grand challenge to mimic and also a great, In the 1970’s, tactile sensing for robotic applications, creasing during the next decade and led to one of the, first overview papers on tactile sensing by Harmon in, vanced robotic grippers such as the DLR RO, force/torque sensors, integrated actuator, and also analog. McCammon, I. Because of this, important properties such as tissue compliance, viscosity and surface texture, which give indications regarding the health of the tissue, cannot easily be assessed. We present a hierarchy consisting of raw, contact, object, and action levels to structure the tactile information, with higher-level information often building upon lower-level information. In. Purbrick, J. Considerable effort in the 1980s was spent investigating transduction techniques and developing new sensors, whilst emphasis in more recent research has focused on experiments using tactile sensors to perform a variety of tasks.This paper reports on progress in tactile sensing in the following areas: cutaneous sensors, sensing fingers, soft materials, industrial robot grippers, multifingered hands, probes and whiskers, analysis of sensing devices, haptic perception, processing sensory data and new application areas.We conclude that the predominant choice of transduction method is piezoelectric, with arrays using resistive or capacitive sensing. Tactile sensors aim to overcome this loss of sensation by detecting tissue characteristics such as stiffness, composition and temperature. An additional downside, is that when using a force/torque sensor inside the finger-, tip, we cannot tell the difference between multi-point and. sensing elements based on optical connection. them and some of their products are presented below as ex-, amples of what performance-wise well known hardware is, crease by the addition of complete integrated tactile sys-. Case Study: Capacitive Tactile Sensors In Robotics The development of RoboTouch sensor technology began in a robotics lab in the early 1990’s with a dream to give robots the “Sense of Touch”. Distributed tactile sensors, or “artificial skin” offer a map of tissue properties in a single instance but are often not suitable for MIS applications due to limited biocompatibility or large collapsed volumes. arrays can be overwhelming, and even if it can be managed. They provide the ability to detect gentle contacts in the range of one to several dozen grams, and can be easily embedded into soft rubber (Tenzer, 2014). briefly discussed and compared to the human tactile sense. weight or center of gravity can be estimated. MEMS barometers have found widespread application in consumer mobile devices such as GPS locators, … Recent progress in tactile sensing and sensors for robotic manipulation: can we turn tactile sensing into vision? 1 Portions of this work were previously presented at the Robotics Symposia 2018, Toyama, Japan.
