Title: Haptic communication between humans and with robots
Abstract: Robotic systems are increasingly used to work in physical contact with humans, but these contact robots have so far made little use of the opportunities of interactive control. We have found recently that mechanically connected humans benefit from the interaction force to exchange task information, identify each other’s control, and improve own performance. This presentation will present these results on human-human behaviour and their computational modelling. It will derive robotic translation of the control principles, enabling sensory augmentation and optimally shared effort between interacting humans or/and robots.

Title: Bioinspired curved image sensor array
Abstract: Although recent efforts in device designs and fabrication strategies have resulted in meaningful progresses to the goal of soft optoelectronics, significant challenges still remain in fabricating a soft form of the image sensor array, particularly in the case of system level integration with inspiration from the human eye. In this presentation, we report our recent achievement in a high-density soft curved image sensor (CurvIS) array by using a heterostructure of inherently soft 2D materials (MoS2 and graphene), by employing an ultrathin device structure, and by applying strain-isolating/-releasing array designs. This high-density soft CurvIS array with the single-lens optics successfully acquires pixelated images without optical aberration and infrared noises. We also present a human-eye-inspired soft implantable optoelectronic device based on the developed CurvIS array. Theoretical analysis in conjunction with supporting experiments corroborates the validity of the proposed soft materials and device designs.

Title: Integration of Tactile and Proximity Perception with Capacitive Sensing Technologe
Abstract: The combination of Tactile Perception and Proximity Perception technologies has the potential to play an essential role for service, industrial robotics, HRC, compliant robotics applications and even bio-inspired robotics in the near future as it allows for novel control strategies for exploration, grasping, manipulation and interaction with humans. However, sensor elements for both perception tasks need to share the space when they are integrated e.g. in a sensor skin. The sensor elements of capacitive sensors are just conductive areas that can be extremely thin, bendable and stretchable and can be used for both, proximity and tactile perception. Beyond that, the sensor elements may also be part of a wireless communication and even of energy harvesting. The presentation will address such integration aspects and benefits of the combination of Tactile and Proximity Perception.

Title: Tactile Sensing and Manipulation in Medical Applications
Abstract:Tactile sensing and bio-inspired design of human-like tools will enhance manipulation skills and humans’ abilities reproduction. Besides humanoid robots and prosthetics applications, other areas such as minimally invasive laparoscopic surgery could benefit from the use of suitably designed and sensorized tools with reconfiguratio capabilities. This talk will present the PRISMA Hand II, an anthropomorphic prosthetic hand endowed with force sensors at the fingertips. Using novel COmpliant Rolling-contact Element (CORE) joints, the hand has a simple structure and exhibits compliance in multiple directions. A surgical tool, the MUSHA Hand II will be presented as well. The tool has three miniature underactuated fingers composed of multiple vertebrae and internal elastic elements; the six degrees of actuation allow the hand to be configured to grasper mode or re-tractor mode for different organ manipulation tasks.Three-dimensional force sensors are integrated into the fingertips to provide the surgeon with the sense of touch and force information.

Title: Vehicle Interiors as Sensate Environments – Tactile Robotics and Artificial Intelligence Transforming the Future in-Car Experience
Abstract: A vehicle’s interior can already now be considered a highly interactive sensate environment. With the advent of highly automated driving, even more emphasis will be on this smart space and the corresponding user experience. New interior layouts become possible, with the attention shifting from the driver to the wellbeing and comfort of rider passengers in highly reconfigurable interior layouts. Smart materials, an array of sensors, robotic mechatronics, and intelligent perception will provide vehicles with more capabilities to sense and interact with their human counterparts. Tactile intelligence in particular will add an exciting new modality and help address challenges of safe human-robot coexistence.
Grasping and Manipulation
Prof. Oliver Brock
Professor of Robotics in the School of Electrical Engineering and Computer Science at the Technische Universität Berlin, Germany
Title: Sensing for Soft Manipulation: If, What, and How — and Can You Hear It?
Abstract: Soft Manipulation is blurring the boundaries between sensing, perception, control, morphology, and planning. For example: soft hands, by complying to the environment in interesting ways, perform sensing and control without physical sensors or explicit computation. This simplifies perception, control, and planning — but it challenges existing system design wisdom. In this presentation, I will explore the opportunities and consequences of blurring the boundaries between sensing, perception, control, morphology, and planning in the context of manipulation. New questions arise: (when) do we need sensing? What should we sense? How should we integrate sensors into new materials and soft-material robots?

Title: A vision for tactile dexterity and reactive manipulation
Abstract: Tactile sensing plays a privileged role in the manipulation chain: it is in direct contact with the world, potentially offering direct observations of shape, motion and force at contact. Robot’s limited tactile reasoning, however, is one of the main limitations of current robotic manipulation systems, and a long-standing challenge in the robotics research community. After decades of advances in sensing instrumentation and processing power, basic questions remains: How should robots make effective use of sensed contact information? How do we plan interactions that render useful tactile information? How de we exploit tactile feedback to simplify planning and control? In this talk I will describe current work on developing a reactive manipulation planning framework to handle objects using tactile feedback.

Title: MAT: Multi-Fingered Adaptive Tactile Grasping via Deep Reinforcement Learning
Abstract: Vision-based grasping systems typically adopt an open-loop execution of a planned grasp. This policy can fail due to many reasons, including ubiquitous calibration error. Recovery from a failed grasp is further complicated by visual occlusion, as the hand is usually occluding the vision sensor as it attempts another open-loop regrasp. This work presents MAT, a tactile closed-loop method capable of realizing grasps provided by a coarse initial positioning of the hand above an object. Our algorithm is a deep reinforcement learning (RL) policy optimized through the clipped surrogate objective within a maximum entropy RL framework to balance exploitation and exploration. The method utilizes tactile and proprioceptive information to act through both fine finger motions and larger regrasp movements to execute stable grasps. A novel curriculum of action motion magnitude makes learning more tractable and helps turn common failure cases into successes. Careful selection of features that exhibit small sim-to-real gaps enables this tactile grasping policy, trained purely in simulation, to transfer well to real world environments without the need for additional learning. Experimentally, this methodology improves over a vision-only grasp success rate substantially on a multi-fingered robot hand. When this methodology is used to realize grasps from coarse initial positions provided by a vision-only planner, the system is made dramatically more robust to calibration errors in the camera-robot transform.

Title: Distributed 3D tactile sensing for robotic grasping and manipulation
Abstract: I will present an overview of the research in our lab on developing tactile sensors for robot hands, grippers and arms, and using those sensors for tasks such as grasp stability analysis and dexterous in-hand manipulation. In particular, we will present a skin sensor system, which is soft, can cover various parts of the robot hand and measure force in 3-axis. Each 3-axis sensor is about 4x4x4mm3 big and has digital output. 272 of such 3-sensors have been used to cover all segments of the Allegro hand fingers, with minimal wiring. We will also present skin sensors for safe robot arms.

Title: Tactile sensing based on soft morphology: from small scale to large scale
Abstract: In our laboratory, we focus on science and technology of morphological computation for recognition of efficient motory and sensory system, especially haptic interaction and tactile sensing. Human’s skin is not only the largest organ, but also a very sophisticated touch system that help humans perceive surroundings’ acute contact, resulting in unique feedback for dexterous manipulation, texture exploration (fingers, hands) and emotional communication (whole body). Human skin is also soft, and has it own unique morphology (finger print, wrinkles), and its mechanism contributing to tactile sensation remained interesting. In this talk, I will present two representative development at small and large scale. First, I will introduce the role of wrinkled morphology toward implementation of small-scale active sensing based on dynamic changing of the skin, which results in variation of underneath mechanoreceptors. Second, a newly-developed whole-arm tactile sensing technology will be introduced. This large-scale robotic skin has high resolution and can sense both deformation and force distribution under contact with the surrounding. These two development shows the potential of softness and morphological computation in development of soft, flexible sensing devices for robotic manipulation and human-robot interaction.
