"Resiliant Formations of Robots"

10:00 a.m., Room 337, Towne Building

Abstract:

The consensus algorithm has many applications in robotics related to distributed decision making. In a group of robots, the success of the algorithm depends on each robot sharing the appropriate information with its neighbors. When some robots do not follow the proper algorithm, the consensus can be impeded or manipulated. In this talk, I present result that allow formations of robots to achieve consensus despite the presence of malicious robots, making them resilient to robot malfunctions or adversarial behavior.

"Stretching the Boundaries of Medical Robotics"

Abstract:

My lab creates medical robots not only for minimally invasive surgery, but also for targeted drug delivery and for tissue regeneration. This talk will describe three of our technologies. The first consists of tetherless robots that are powered, controlled and imaged using an MRI scanner. These devices vary from patient-mounted needle-driving robots to capsules that can move inside fluid-filled body lumens. The second technology consists of a class of robot implants designed to apply traction forces over a period of weeks inside the body so as to induce the regeneration of soft tissues. Applications include lengthening the esophagus and bowel for the treatment of congenital defects and disease. The third is a type of continuum robot that is based on concentrically combining pre-curved superelastic tubes. We are using this technology to create multi-armed systems for intracranial endoscopic surgery. We are also developing endoscopically-guided catheters that can navigate autonomously inside the blood-filled beating heart.

Douglas J. Jerolmack, Professor of Earth and Environmental Sciences, University of Pennsylvania

"Viewing Earth's Surface as a Soft Matter Landscape"

Abstract:

The Earth's surface is composed of a staggering diversity of particulate-fluid mixtures: dry to wet, dilute to dense, colloidal to granular, attractive to repulsive particles, laminar to turbulent flows, and steady to highly-unsteady forcing. This material variety is matched by the range of relevant stresses and strain rates, from rapid and catastrophic landslides to the slow relaxation of soil over geologic timescales. In this talk I illustrate the commonalities and challenges in understanding geophysical flows by highlighting two problems: gravity-driven downslope soil movement, and fluid-driven particle transport in rivers.

Soil on hillslopes slowly and imperceptibly creeps downhill, but suddenly liquefies to produce landslides. The transition between creeping and flowing is a yield condition, often defined in terms of the shear stress, that depends on the characteristics of the soil and the geologic environment. We show that the nature of this transition, however, is general. Creep is the localized and erratic motion of soil grains below yield; because this kind of fragility is a generic consequence of disorder, soil creep should be similar to amorphous glass. Indeed, we find that the transition from creeping to landsliding is a continuous phase transition that follows predictions from glass transition models. The generality of this transition suggests that the onset of sediment transport in rivers should behave in a similar manner, and we demonstrate that this is the case using laboratory experiments and simulations. Because the sediment transport rate rapidly increases for stresses above yield, many landscapes such as rivers organize to be close to the yield point. In essence, landscapes flicker back and forth across the glass transition. We explore several consequences of these dynamics for the sculpting of landscapes.

January 25 (Friday): MEAM/GRASP Seminar

Howie Choset, Kavcic-Moura Professor of Computer Science, Carnegie Mellon University

"Geometric Biologically Inspired Robots that Span Industries from Medical to Manufacturing"

11:00 a.m., Wu and Chen Auditorium, Levine Hall

Abstract:

The animal kingdom is full of both human and non-human animals worthy of investigation, emulation and re-creation. As such, my research group has created a comprehensive research program focusing on biologically-inspired robots, and has applied them to search and rescue, minimally invasive surgery, and manufacturing. These robots inspire great scientific challenges in mechanism design, control, planning and estimation theory. These research topics are important because once the robot is built (design), it must decide where to go (path planning), determine how to get there (control), and use feedback to close the loop (estimation). A common theme to these research foci is devising ways by which we can reduce multi-dimensional problems to low dimensional ones for planning, analysis, and optimization. In this talk, I will discuss our results in geometric mechanics, Bayesian filtering, and scalable multi-agent planning to support these reductions. This talk will also cover how my students and I commercialized these technologies by founding three companies: Medrobotics, Hebi Robotics, and Bito Robotics. In 2015, the surgical snake robot from Medrobotics cleared the FDA and has begun to democratize the delivery of medical care in the US and Europe If time permits, I will also discuss my educational activities, especially at the undergraduate level, with a course using LEGO robots, and the role of entrepreneurism in University education.

This work has contributed to strategically significant problems in diverse areas such as surgery, manufacturing, infrastructure inspection, and search and rescue. In addition to publications, this work has led to Choset, along with his students, to form several companies including Medrobotics, for surgical systems, Hebi Robotics, for modular robots, and Bito Robotics for autonomous guided vehicles.

"Elastomeric Materials for Autonomic Force Transmission, Optoelectronic Sensing, and 3D Printing Soft Robots"

Abstract:

This talk will present multidisciplinary work from material composites and robotics. We have created new types of actuators, sensors, displays, and additive manufacturing techniques for soft robots and haptic interfaces. For example, we now use stretchable optical waveguides as sensors for high accuracy, repeatability, and material compatibility with soft actuators. For displaying information, we have created stretchable, elastomeric light emitting displays as well as texture morphing skins for soft robots. We have created a new type of soft actuator based on molding of foams, and stereolithography printing of elastomer based soft robots, and implemented deep learning in stretchable membranes for interpreting touch. All of these technologies depend on the iterative and complex feedback between material and mechanical design. I will describe this process, what is the present state of the art, and future opportunities for science in the space of additive manufacturing of elastomeric robots.

"Hairy Hydrodynamics"

Abstract:

Flexible slender structures in flow are everywhere. While a great deal is known about individual flexible fibers interacting with fluids, considerably less work has been done on fiber ensembles — such as fur or hair — in flow. These hairy surfaces are abundant in nature and perform multiple functions from thermal regulation to water harvesting to sensing. Motivated by these biological systems, we consider several examples of hairy surfaces interacting with flow including drinking bats and diving sea otters. In the first example we consider viscous dipping, a feeding method utilized by many nectar drinking animals. This mechanism is reminiscent of Landau-Levich-Derjaguin (LLD) dip coating, and has been analyzed through the LLD framework in previous studies. However, many viscous dippers have hairy structures on their tongues that enhance fluid uptake. In this study, we investigate the impact of mesoscale hairy structures on feeding efficiency. In the second example, we take inspiration from semi-aquatic mammals (such as fur seals, otters, and beavers) which have specially adapted fur that serves as an effective insulator both above and below water. Many of these animals have evolved pelts that naturally entrap air when they dive. Here we investigate diving conditions and fur properties which amplify air entrainment.

"Fluid Mechanics and Turbulence in Extended Wind Farms"

Abstract:

In this presentation we discuss several properties of the flow structure and turbulence in the wind turbine array boundary layer (WTABL). This particular type of shear flow develops when the atmospheric boundary layer interacts with an array of large wind turbines. Based on such understanding, we aim to develop reduced order, analytically tractable models. These are important engineering tools for wind energy, both for design and control purposes. We will focus on two fluid mechanical themes relevant to wind farm design and control. The first topic deals with spectral characteristics of the fluctuations in power generated by an array of wind turbines in a wind farm. We show that modeling of the spatio-temporal structure of canonical turbulent boundary layers coupled with variants of the Kraichnan’s random sweeping hypothesis can be used to develop analytical predictions of the frequency spectrum of power fluctuations of wind farms. In the second part we describe a simple (deterministic) dynamic wake model, its use for wind farm control, and its extension to the case of yawed wind turbines. The work to be presented arose from collaborations with Juliaan Bossuyt, Johan Meyers, Richard Stevens, Tony Martinez, Michael Wilczek, Carl Shapiro and Dennice Gayme. We are grateful for National Science Foundation support.

"Modeling and Control for Robotic Assistants: Single and Multi-Robot Manipulation"

12:00 p.m., East Conference Room 303, Pennovation Center, 3rd Floor (PERCH)

Abstract:

As advances are made in robotic hardware, the capacity of the complexity of tasks they are capable of performing also increases. One goal of modern robotics is to introduce robotic platforms that require very little augmentation of their environments to be effective and robust. Therefore the challenge for the Roboticist is to develop algorithms and control strategies that leverage knowledge of the task while retaining the ability to be adaptive, adjusting to perturbations in the environment and task assumptions. This work considers approaches to these challenges in the context of a wet-lab robotic assistant. The tasks considered are cooperative transport with limited communication, and robot-assisted rapid experiment preparation requiring pouring from open containers useful for research and development scientist. For cooperative transport, robots must be able to plan collision-free trajectories and agree on a final destination to minimize internal forces on the carried load. Robot teammates are considered, where robots must reach consensus to minimize internal forces. Human leader, robot follower is then considered where robots must use non-verbal information to estimate the human leaders intended pose for the carried load. For experiment preparation, the robot must pour precisely from open containers in a single attempt. Two scenarios examined are when both pourer and receiver geometries and behaviors are known, and when the pourer must be approximated. An analytical solution is presented for a given geometry in the first instance. In the second instance, a combination of online system identification and leveraging of model priors are used to achieve the precision-pour in a single attempt with considerations for long-term robot deployment. The main contributions of this work are considerations for making robots capable of performing complex tasks with an emphasis on methods to combine classical and modern approaches for best performance.

"Nanoparticle Heating for Therapeutics, Regenerative Medicine and Diagnostics"

Abstract:

Gold and iron oxide nanoparticles have unique and tunable properties that allow transduction of optical (light), or radiofrequency (RF) electromagnetic fields to affect heating of biomaterials at multiple scales. This talk will explore the underlying physics and relative advantages of each form of nanoparticle heating for therapeutic treatment of cancer or other disease by heating (i.e. magnetic hypothermia or photothermal cancer therapy). In addition, this same heating helps improve regenerative medicine by "nanowarming" vitrified (i.e. cryopreserved) biomaterials back to a transplantable state through rapid and uniform warming that avoids crystallization and cracking. This nanoparticle warming addresses an important technology bottleneck for both large systems (i.e. tissues and organs) and smaller systems (i.e. embryos and oocytes). In summary, this talk demonstrates the growing opportunites for nanoparticle heating in biomedical applications.

"Force, Shape, and Motion in Collective Cell Migration"

Abstract:

Cells migrate collectively to form tissues, to heal wounds, and, in cancer, to metastasize. During these biological processes, the collective migration exhibits a transition from a solid-like state, wherein cell positions remain fixed, to a fluid-like state, wherein cells flow freely and rearrange their positions with their neighbors. Recent mechanics-based models and experiments have demonstrated that this transition can be predicted by average cell shape, with cells having more elongated shapes and greater perimeters more easily sliding past their neighbors. At each cell-cell interface, it has been proposed that active actomyosin contraction generated within the cell cortex acts as an effective surface tension tending to reduce each cell’s perimeter. Cell-cell adhesions have the opposite effect, tending to reduce the surface tension, thereby increasing the perimeter. It is unclear how cells regulate these competing factors in a confluent monolayer. This presentation will describe our investigation of the factors affecting cell surface tension and cell perimeter, and the corresponding effects on collective migration. Our experiments use monolayers of Madin-Darby Canine Kidney cells and quantify cell forces, shapes, and motion. With this experimental data, we test the theoretical predictions relating cell shape and motion.

"Additive Manufacturing and Architected Materials"

Abstract:

Material properties are governed by the chemical composition and spatial arrangement of constituent elements. Over the past decade, the field of architected materials has sought to design, fabricate, and demonstrate materials with performance that is fundamentally controlled by geometry at multiple length-scales rather than chemical composition alone. There have been many advancements ranging from the maturation of additive manufacturing technologies which can be used to realize these materials, to inverse design methods such as topology optimization, and even includes unique new material feedstocks which make up the structures. This presentation will touch on all aspects of the architected materials realization process as well as evaluate performance of some of those materials. Specifically, we have demonstrated designer properties of these architected materials in polymers, metals, ceramics and combinations thereof. In addition to novel properties such as ultra-stiff lightweight materials, negative stiffness, and negative thermal expansion, I will present multifunctional architected materials with energy storage capability and architectures that respond to external fields. Many of these architected materials derived from advanced design and optimization methods which we have been developing and were fabricated with custom additive manufacturing techniques. These include projection microstereolithography (PµSL), direct ink writing (DIW), electrophoretic deposition (EPD), volumetric additive manufacturing (VAM), computed axial lithography (CAL), and diode-based additive manufacturing (DiAM) to name a few. New materials including graphene aerogel, carbon fiber composites, and printed glass will also be touched upon.

"Integrating Manufacturing and Topology Optimization for the Design of Architected Materials and Components"

Abstract:

Topology optimization has long been touted as a powerful tool capable of discovering innovative solutions to engineering design problems. It has been used to design 'structures' characterized at a range of length scales, from tens of microns (material architectures) to decameters (structures), for performance properties governed by a range of physics. Despite its tremendous potential as a design tool, topology optimized solutions are typically suboptimal when considering real-world operating conditions, design objectives, and manufacturing processes, and thus may require significant post-processing and re-design which is both detrimental and time consuming. This talk will review the topology optimization methodology and discuss our efforts at overcoming these shortcomings, with a particular emphasis on providing the design engineer geometric control to enable design for manufacturability. Several design examples will be presented including architected materials, components and devices that are fabricated through additive manufacturing, machining or 3D weaving, and optimized for mechanical, fluidic, and/or thermal properties.
