Book Description
Scientific and engineering literature extensively discusses untethered miniature devices, also called bots, as those parts of medical robotic systems that can be manipulated remotely within the human body. There is clear evidence that this topic has gained significant traction based on the spike in publication over the past seven years (Koleoso et al., 2020). Robotic systems that employ micro- and millimeter size bots are thought to have numerous potential medical applications including drug delivery (Jang et al., 2019), localized heating or cooling, cessation of bleeding, clearing of occlusions, establishing a diagnosis based on sensing or biopsy, and minimally invasive surgeries. Most studies focuses on the actuation and control of such bots in fluid environment, typically at low Reynolds numbers. Yet, many medical applications would involve soft tissues, rather than fluids. While controlling tethered devices, such as needles, based on appropriate models of interaction with tissue has been the subject of considerable interest. However, no similar work has been published for untethered miniature devices. The goal of the present thesis is to develop trajectory planning and control methods for untethered solid millimeter size bots in soft tissue under the action of magnetic force. This study employs a recently developed model describing the interaction of untethered bots with soft materials during bot motion by implementing a numerical simulation of the model. Given the highly non-linear and past trajectory (history) dependent nature of the interaction with the medium, in addition to significant model parameter variability throughout soft media, the present thesis hypothesizes that a trajectory control based on the so-called Sliding Mode Control (SMC) method will make it possible for a bot to follow a large class of practical trajectories accurately. Numerical simulations of the proposed SMC method were conducted and experimentally validated for a class of trajectories that could be well approximated by circular and straight segments. The robustness of the proposed method was analyzed numerically by simulating trajectories in media with random variations of various model parameters as well as in the presence of significant delays in the feedback signal used to estimate the bot position. All the work carried out in this thesis applies to bots that are spherical making it possible to simplify the model, trajectory control, and their experimental validation. Furthermore, experimental validations are limited in this work to bots that are on the order of millimeters in diameter. While smaller bots may be of interest in medicine, they would be significantly harder to actuate and image during experimental validation experiments. At the same time, millimeter size bots are commensurate with the typical dimensions of needles widely employed in medical applications.

Book Description
The first textbook on micron-scale mobile robotics, introducing the fundamentals of design, analysis, fabrication, and control, and drawing on case studies of existing approaches. Progress in micro- and nano-scale science and technology has created a demand for new microsystems for high-impact applications in healthcare, biotechnology, manufacturing, and mobile sensor networks. The new robotics field of microrobotics has emerged to extend our interactions and explorations to sub-millimeter scales. This is the first textbook on micron-scale mobile robotics, introducing the fundamentals of design, analysis, fabrication, and control, and drawing on case studies of existing approaches. The book covers the scaling laws that can be used to determine the dominant forces and effects at the micron scale; models forces acting on microrobots, including surface forces, friction, and viscous drag; and describes such possible microfabrication techniques as photo-lithography, bulk micromachining, and deep reactive ion etching. It presents on-board and remote sensing methods, noting that remote sensors are currently more feasible; studies possible on-board microactuators; discusses self-propulsion methods that use self-generated local gradients and fields or biological cells in liquid environments; and describes remote microrobot actuation methods for use in limited spaces such as inside the human body. It covers possible on-board powering methods, indispensable in future medical and other applications; locomotion methods for robots on surfaces, in liquids, in air, and on fluid-air interfaces; and the challenges of microrobot localization and control, in particular multi-robot control methods for magnetic microrobots. Finally, the book addresses current and future applications, including noninvasive medical diagnosis and treatment, environmental remediation, and scientific tools.

Book Description
Small robots that can be manufactured rapidly and inexpensively have numerous scientific applications. Current manufacturing processes for robots are made specific to the robot, with little application beyond the shape and size of the target robot. The idea of magnetically-controlled, self-folding origami robots has been proposed to enable universal robot construction on this scale. This thesis continues the investigation into miniature magnetic origami robots by exploring specifically the design and control of such robots. We detail our heat-activated self-folding process and its thermal constraints. We further explore design principles for robots using this self-folding strategy, culminating in the design and performance of an untethered, walking, swimming robot. We develop a control method for the robots utilizing a novel electromagnetic coil system that does not enclose the workspace of the robot. We model the magnetic field of the robot and the generated field from the electromagnetic coil system, and we explore their influences on the frequency and speed response of the robots due to induced motion. We develop a manual and autonomous controller to drive the robot through oscillitory walking motion. We develop a novel method of localization using Hall effect sensors to enable position feedback control as well as vision-based localization and path planning. Finally, we examine magnetically-controlled assembly using special exoskeleton robots as well as medical applications within the gastrointestinal system.
