Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the creation and control of soft robots made of deformable elastomer materials and powered by fluidics. We embed soft fluidic actuators into self-contained soft robotic systems, such as fish for underwater exploration or soft arms for dynamic manipulation. We present models describing the physical characteristics of these continuously deformable and fully soft robots, and then leverage these models for motion planning and closed-loop feedback control in order to realize quasi-static manipulation, dynamic arm motions, and dynamic interactions with an environment. The design and fabrication techniques for our soft robots include the development of soft actuator morphologies, soft casting techniques, and closed-circuit pneumatic and hydraulic powering methods. With a modular design approach, we combine these soft actuator morphologies into robotic systems. We create a robotic fish for underwater locomotion, as well as multi-finger hands and multi-segment arms for use in object manipulation and interaction with an environment. The robotic fish uses a soft hydraulic actuator as its deformable tail to perform open-loop controlled swimming motions through cyclic undulation. The swimming movement is achieved by a custom-made displacement pump and a custom-made buoyancy control unit, all embedded within the soft robotic fish. The fish robot receives high-level control commands via acoustic signals to move in marine environments. The control of the multi-segment arms is enabled by models describing the geometry, kinematics, impedance, and dynamics. We use the models for quasi-static closed-loop control and dynamic closed-loop control. The quasi-static controllers work in combination with the kinematic models and geometric motion planners to enable the soft arms to move in confined spaces, and to autonomously perform object grasping. Leveraging the models for impedance and dynamics, we also demonstrate dynamic arm motions and end-effector interactions of the arm with an environment. Our dynamic model allows the application of control techniques developed for rigid robots to the dynamic control of soft robots. The resulting model-based closed-loop controllers enable dynamic curvature tracking as well as surface tracing in Cartesian space.

This book was released on 2015 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this thesis is to explore how autonomous robotic systems can be created with soft elastomer bodies powered by fluids. In this thesis we innovate in the design, fabrication, control, and experimental validation of both single and multi-segment soft fluidic elastomer robots. First, this thesis describes an autonomous fluidic elastomer robot that is both self-contained and capable of rapid, continuum body motion. Specifically, the design, modeling, fabrication, and control of a soft fish is detailed, focusing on enabling the robot to perform rapid escape responses. The robot employs a compliant body with embedded actuators emulating the slender anatomical form of a fish. In addition, the robot has a novel fluidic actuation system that drives body motion and has all the subsystems of a traditional robot on-board: power, actuation, processing, and control. At the core of the fish's soft body is an array of Fluidic Elastomer Actuators (FEAs). The fish is designed to emulate escape responses in addition to forward swimming because such maneuvers require rapid body accelerations and continuum body motion. These maneuvers showcase the performance capabilities of this self-contained robot. The kinematics and controllability of the robot during simulated escape response maneuvers are analyzed and compared to studies on biological fish. During escape responses, the soft-bodied robot is shown to have similar input-output relationships to those observed in biological fish. The major implication of this portion of the thesis is that a soft fluidic elastomer robot is shown to be both self-contained and capable of rapid body motion. Next, this thesis provides an approach to planar manipulation using soft fluidic elastomer robots. That is, novel approaches to design, fabrication, kinematic modeling, power, control, and planning as well as extensive experimental evaluations with multiple manipulator prototypes are presented. More specifically, three viable manipulator morphologies composed entirely from soft silicone rubber are explored, and these morphologies are differentiated by their actuator structures, namely: ribbed, cylindrical, and pleated. Additionally, three distinct casting-based fabrication processes are explored: lamination-based casting, retractable-pin-based casting, and lost-wax- based casting. Furthermore, two ways of fabricating a multiple DOF manipulator are explored: casting the complete manipulator as a whole, and casting single DOF segments with subsequent concatenation. An approach to closed-loop configuration control is presented using a piecewise constant curvature kinematic model, real-time localization data, and novel fluidic drive cylinders which power actuation. Multi-segment forward and inverse kinematic algorithms are developed and combined with the configuration controller to provide reliable task-space position control. Building on these developments, a suite of task-space planners are presented to demonstrate new autonomous capabilities from these soft robots such as: (i) tracking a path in free-space, (ii) maneuvering in confined environments, and (iii) grasping and placing objects. Extensive evaluations of these capabilities with physical prototypes demonstrate that manipulation with soft fluidic elastomer robots is viable. Lastly, this thesis presents a robotic manipulation system capable of autonomously positioning a multi-segment soft fluidic elastomer robot in three dimensions while subject to the self-loading effects of gravity. Specifically, an extremely soft robotic manipulator morphology that is composed entirely from low durometer elastomer, powered by pressurized air, and designed to be both modular and durable is presented. To understand the deformation of a single arm segment, a static physics-based model is developed and experimentally validated. Then, to kinematically model the multi-segment manipulator, a piece-wise constant curvature assumption consistent with more traditional continuum manipulators is used. Additionally, a complete fabrication process for this new manipulator is defined and used to make multiple functional prototypes. In order to power the robot's spatial actuation, a high capacity fluidic drive cylinder array is implemented, providing continuously variable, closed-circuit gas delivery. Next, using real-time localization data, a processing and control algorithm is developed that generates realizable kinematic curvature trajectories and controls the manipulator's configuration along these trajectories. A dynamic model for this multi-body fluidic elastomer manipulator is also developed along with a strategy for independently identifying all unknown components of the system: the soft manipulator, its distributed fluidic elastomer actuators, as well as its drive cylinders. Next, using this model and trajectory optimization techniques locally-optimal, open-loop control policies are found. Lastly, new capabilities offered by this soft fluidic elastomer manipulation system are validated with extensive physical experiments. These are: (i) entering and advancing through confined three-dimensional environments, (ii) conforming to goal shape-configurations within a sagittal plane under closed-loop control, and (iii) performing dynamic maneuvers we call grabs.

Download or read book Soft Robotic Actuation with Pressure-driven Magnetorheological (MR) Fluid Flow written by Anna Maria Moran and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft robots can complete tasks that rigid robots cannot. These compliant, dexterous machines are well suited to delicate tasks in difficult environments such as within the human body and the deep sea. Fluidically actuated robots are popular due to their simple design, high force output, and safety. However, complex robots often consist of many actuators working together. These actuators can be difficult to control independently, and require many bulky tubes limiting the robots’ autonomy. Many techniques have been employed to integrate pressure control directly onboard the robots themselves, including using smart fluids like magnetorheological fluid (MRF). This project explores the use of MRF to actuate soft robots. The device flows MRF through the actuator using a peristaltic pump, and an applied magnetic field initiates actuation by locally solidifying the fluid. This creates a pressure buildup in the actuator, which bends due to a differential stiffness. We investigate how different properties of the MRF (particle size, non-Newtonian rheology, etc.) affect actuation efficacy. The actuation efficacy is quantified by the speed of actuation and the force produced by the actuator. The results are compared to determine the best combination of MRF parameters and device architecture for robust actuation.

Book excerpt: The research areas as well as the knowledge gained for the practical use of robots are growing and expanding beyond manufacturing and industrial automation, making inroads in sectors such as health care and terrain sensing, as well as general assistive systems working in close interaction with humans. In a situation like this, it is necessary for future robot systems to become less stiff and more specialized by taking inspiration from the mechanical compliance and versatility found in natural materials and organisms. At present, a new discipline is emerging in this area, called »Soft Robotics«. It particularly challenges the traditional thinking of engineers, as the confluence of technologies, ranging from new materials, sensors, actuators and production techniques to new design tools, will make it possible to create new systems whose structures are almost completely made of soft materials, which bring about entirely new functions and behaviors, similar in many ways to natural systems. These Proceedings focus on four main topics: • Soft Actuators and Control • Soft Interactions • Soft Robot Assistants: Potential and Challenges • Human-centered »Soft Robotics«.

Book Synopsis Enabling Soft Robotic Systems by : Mohammed Al-Rubaiai
Download or read book Enabling Soft Robotic Systems written by Mohammed Al-Rubaiai and published by . This book was released on 2021 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft robots have appealing advantages of being highly flexible and adaptable to complex environments. This dissertation is focused on advancing key enabling elements for soft robots, including providing new solutions to stiffness-tuning, integrated sensing, and modeling and control of soft actuation materials.First, a compact and cost-effective mechanism for stiffness-tuning is proposed based on a 3D-printed conductive polylactic acid (CPLA) material. The conductive nature of the CPLA allows convenient control of temperature and stiffness via Joule heating in a reversible manner. A gripper composed of two soft actuators as fingers is fabricated to demonstrate localized gripping posture, passive shape holding, and the ability to carry load in a desired locked configuration.Second, two types of integrated sensors are proposed. The first type is 3D-printed strain sensors that can be co-fabricated with soft robot bodies. Three commercially available conductive filaments are explored, among which the conductive thermoplastic polyurethane (ETPU) filament shows the highest sensitivity (gauge factor of 20) and working strain range of 0%-12.5%. The ETPU strain sensor exhibits an interesting behavior where the conductivity increases with the strain. In addition, the resistance change of the ETPU sensor in a doubly-clamped configuration in response to a wind stimulus is characterized, and the sensor shows sensitivity to wind velocity beyond 3.5 m/s.We then present a soft pressure-mapping sensing system that is lightweight and low-cost, and can be integrated with inflatable or textile structures with minimal impact on the original substrate characteristics. The sensing system involves two layers of piezoresistive foil and three layers of conductive copper sheets, stacked on top of each other in an orderly manner, to detect the magnitude and the location of applied load, respectively. Extensive experiments on a sensor prototype with dimensions of 35x500 mm mounted on an inflatable tube are conducted to demonstrate the capability of the proposed scheme in simultaneous measurement of deformation location and magnitude. In particular, it is shown that the specific design approach minimizes the coupling of location and magnitude measurements, resulting in minimal complexity for data processing.Finally, we investigate the modeling and control of soft actuation materials, specifically accommodating their nonlinear dynamics. Polyvinyl chloride (PVC) gel actuators are considered in this work. A nonlinear, control-oriented Hammerstein model, with a polynomial nonlinearity preceding a transfer function, is proposed to capture the amplitude and bias-dependent frequency response of PVC gel actuators. A trajectory-tracking controller is developed, where an inverse is used to cancel the effect of the nonlinearity and a disturbance estimator/compensator is adopted to mitigate the influence of model uncertainties and disturbances. The efficacy of the proposed modeling and control approach is demonstrated experimentally in comparison with alternative methods, where the PVC actuator is commanded to track references of varying frequencies and waveforms.

Download or read book Intelligent Control of Legged Soft Robot written by Carina Elena Kaainoa and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft robots made of soft and extensible materials accomplish tasks via shape-changing by use of pneumatic or fluidic actuation. Dynamic modeling of soft robots has been challenging due to the nonlinearity and heterogeneity inherent from their soft material bodies, therefore, the model-based control methods cannot be directly applied. In this thesis, motion control of a pneumatically actuated quadrupedal soft robot via a combination of reinforcement learning and a dead-band proportional integral derivative controller is proposed. The coordinated rhythmic motion of a soft quadruped robot is governed by the Kuramoto central pattern generator which represents a continuous, smooth control policy with small number of parameters. A reinforcement learning methodology called parameter-exploring policy gradient, a gradient estimation algorithm, is utilized to find the forward motion optimal control policy. Finally, a dead-band proportional integral derivative controller is designed for trajectory control. The effectiveness of the proposed tracking control method is demonstrated via simulation.
Book Synopsis Towards Morphology-agnostic Control for Soft Robots by : Suraj Srinivasan
Download or read book Towards Morphology-agnostic Control for Soft Robots written by Suraj Srinivasan and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of soft robots promises to fundamentally shift the landscape of robotic systems as they offer several advantages over the current paradigm of rigid bodies. Most notably, they provide adaptability to uncertain environments and look to bridge the gap between humans and machines. However, determining the optimal structure of a soft robot for a given task is difficult and complicated by the fact that soft robots have a design-dependent control profile. Thus, existing approaches have relied on human intuition or biomimicry. Co-design has been introduced as an approach to developing soft robots and involves jointly optimizing over the design and control of compliant bodies. An iterative design optimization routine suggests new morphologies while a control optimization subprocess determines a controller for each unique body. However, in its current form, co-design is a lengthy process due to the control optimization step being computationally expensive. Moreover, this step must be carried out separately for every unique morphology. This thesis discusses the development of MANTIS: a Morphology-Agnostic Controller for Soft Robots. We evaluate MANTIS against expert controllers using a soft robotic benchmarking suite (EvoGym) and demonstrate proficiency in zero-shot generalization to unseen morphologies. Importantly, this work makes strides towards universal control for soft robots, an objective which will greatly accelerate the rate of research in soft robotics.

Book Synopsis Soft Materials for Soft Robots by : Yang Wang

Book excerpt: Comparing with traditional robotic design based rigid materials, soft material based robotic design shows unique advantages such as large deformation and great compatibility for many applications such as human-machine-interfaces. The field of soft robotics has witnessed numerous growths of new designs of soft actuators and soft sensors. Even though they show the great uniqueness of using soft materials but many of them do not have a comprehensive performance to adapt to different complex scenarios. Therefore, we came with material-level designs using soft smart materials, such as liquid crystal elastomers and hydrogels, to address this challenge. In this dissertation, we first designed and fabricated an electrically controlled soft actuator with multiple and reprogrammable actuation modes, and then demonstrated a reusable and general-purpose soft actuator which can meet various requirements in constructing new soft active devices. Secondly, we developed an integrated artificial motor unit based on gold-coated ultrathin liquid crystal elastomer (LCE) film. Due to the small thermal inertial of the ultrathin LCE structure, its cyclic actuation speed is fast and easily controllable. We showed that under electrical stimulation, the actuation strain of the LCE-based motor unit reaches 45%, strain rate is as high as 750 %/s, and the output power density is as high as 1360 W/kg. Lastly, we developed a transparent and stretchable hydrogel-based ionic diode based on doped polyacrylamide hydrogels. Using the ionic diode, we further successfully constructed two types of ionic logic gates, which can potentially be used as soft sensors. We hope the material-based designs of soft actuators and soft sensors we developed in this dissertation can be used as the basic functional elements for advanced and integrated soft robotic systems.

Download or read book Physical Intelligence Enabled by Soft Robotic Systems written by Jose Antonio Barreiros Flores and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft robotics is of special interest in the study of physical intelligence, aka. the intelligence that predominantly comes from the physical body and its morphology, due to the compliance of the materials and mechanisms. Soft systems have been demonstrated for complex motion, human-like sensing capabilities, morphing, self-healing, adaptation, and growth; which are abilities highly desirable in intelligent agents to endure the demanding working conditions of the real world. This dissertation explores the use of soft robotic systems as platforms to encode intelligent behavior in the body of the robot, and it presents examples of soft robotic system modules that could facilitate perception, controls and actuation in embodied AI agents, thus composing a better embodiment for them. In an advance for robotic haptic perception systems that could allow an agent to understand its embodiment and its interactions with the environment, I present 1) a self sensing membrane that estimate its deformation state based on capacitive readings and supervised learning models; 2) a stretchable optical fiber that maps bending, stretching and location of pressing into intensity and color of light; and 3) an optoelectronic robotic flesh that is scalable to cover the whole body of a robot and encodes deformation, temperature and damage stimuli into light. In an effort to facilitate controls and complex actuation in robots through means of physical intelligence, I present 1) a tendon driven actuator in which the actuation trajectory is programmed by the placement and number of tendons inside its body; and 2) a fluidic hyperelastic textile actuator that can inflate in complex 3D shapes by locally programming the mechanical properties of its membrane using digital embroidery. The challenges of artificial physical intelligence in soft robots, including fabrication, design, and simulation; and demonstrations of the system modules in real world applications are discussed in each chapter.
