Book Description
Untethered robotic micromanipulators are devices that physically interact with components on the microscale (sizes less than a few millimeters), and usually within a remote workspace, that enhance the precision and accuracy of manipulation by an unaided hand. Addressing the low levels of dexterity, precise kinematics and dynamics, and versatility are the current limitations that have been the focus of recent studies. The two novel methods presented in this thesis use magnetic and acoustic fields to achieve dexterous and precise micromanipulation characteristics to tackle the current gaps. A magneto-acoustic system is developed for magnetic actuation, with sub-body-length precision, of magnetic microrobots for dry surface and levitated contactless micromanipulations and the performances of each method are characterized. The capabilities of both methods are shown by real-world microassembly demonstration for assembly of microscale-sized optical components. For the first time, a permanent magnet sphere was levitated open-loop with small magnetic and acoustic field magnitudes.

Book Description
The field of untethered microrobotics has emerged within the last two decades for its applications potential in military surveillance, micro and nano manufacturing, as well as in health care for minimal invasive surgery and drug delivery. Microrobots need to be fast and precise in order to be useful as a tool for manufacturing applications. It is well understood that at this size scale numerous challenges prevail such as stiction between microrobot and environment, providing power, locomotion control, and intelligence to microrobots and motion measurement. In order to accelerate the research in this field, I participated in the Mobile Microrobotics Challenge (MMC). MMC is an annual event organized by the Institute of Electrical and Electronics Engineers Robotics and Automation Society (IEEE RAS) since 2013 and designed to encourage researchers around the world to solve pressing challenges in microrobotics. The challenge is composed of three events: 1) the autonomous mobility and accuracy challenge, 2) the microassembly challenge and 3) the MMC showcase and poster session. These challenges simulate common tasks that are found in medical applications, involving high speed closed-loop positioning, and in microassembly applications involving precision motion control and the later and the showcase and poster challenge tests your communication skills. This thesis investigates and provides methods to mitigate the problems of stiction, locomotion control, and motion measurement for microrobots. In addition, we discuss novel methods for providing cooperative behavior to multiple microrobots and to estimate and mitigate spatial uncertainty estimation for modular serial link robotic platforms. In this dissertation I describe novel methods to enhance the performance of magnetic microrobots, reduce environmental forces via inexpensive anti-friction coatings, and increase their velocities via novel mechanical amplifiers. Such methods generate swarming motions, with a leader and formation following behavior, and cooperative planar motions compatible with micromanipulation tasks such as grasping. Moreover, I provide a possible application scenario using such cooperative behavior to assemble optical elements.The cooperative grasping behavior is produced by the magnetic field gradient controlled by a modular multi-degree of freedom serial link robot used to position the conical permanent magnet with respect to the robots' workspace. In the course of this research it was necessary to precisely characterize and compensate for the spatial uncertainty of the robot. Spatial uncertainty is an inherent feature of multiple-link robots due to misalignment of joints, link length, resolution of the actuator, the type of joint, the path of motion and the atmosphere of operation. Such uncertainties can be detrimental for robots used in assembly tasks where precision is essential. In order to overcome this fundamental challenge with flexible or modular assembly and packaging systems, I presents a novel precision evaluation and control technique to estimate and track the end-effector position errors in a robotic manipulation system resulting from the kinematic configuration as well as the dynamic parameters for each specific task; thereby, allowing the automation application to compensate for these errors in run-time.

Book Description
Microrobotics is an emerging and booming area with many and various applications, including in fields such as industrial/manufacturing robotics, medical robotics, and laboratory instrumentation. Microrobotics for Micromanipulation presents for the first time, in detail, a treatment of the field of robotics dedicated to handling objects of micrometer dimensions. At these dimensions, the behavior of objects is significantly different from the better known, larger scales, which leads to implementation techniques that can be radically different from the more commonly used solutions. This book details the behaviors of objects at the micrometer scale and provides robotics solutions that are suitable, in terms of actuators, grippers, manipulators, environmental perception, and microtechnology. Worked examples are included in the book - enabling engineers, students and researchers to familiarize themselves with this emerging area and to contribute to its development.

Book Description
This book reports on advances in sensing, modeling and control methods for different robotic platforms such as multi-degree of freedom robotic arms, unmanned aerial vehicles and autonomous mobile platforms. Based on 2018 Symposium on Mechatronics, Robotics, and Control (SMTRC’18), held as part of the 2018 CSME International Congress, in York University, Toronto, Canada, the book covers a variety of topics, from filtering and state estimation to adaptive control of reconfigurable robots and more. Next-generation systems with advanced control, planning, perception and interaction capabilities will achieve functionalities far beyond today’s technology. Two key challenges remaining for advanced robot technologies are related to sensing and control in robotic systems. Advanced perception is needed to navigate changing environments. Adaptive and intelligent control systems must be developed to enable operation in unstructured and dynamic environments. The selected chapters in this book focus on both of the aforementioned areas and highlight the main trends and challenges in robot sensing and control. The first part of the book introduces chapters which focus on advanced perception and sensing for robotics applications. They include sensor filtering and state estimation for bipedal robots and motion capture systems analysis. The second part focuses on different modeling and control methods for robotic systems including flight control for UAVs, multi-variable robust control for modular and reconfigurable robotics and control for precision micromanipulation.

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.
