"Robotic micromanipulation is a widely used experimental technique to physically interact with a microscale sample under a microscope, and has found important applications in cell microinjection, mechanical characterization of biomaterials, and assembly of micro-parts. Force sensing and control play important roles in robotic micromanipulation. For instance, monitoring the contact force in cell injection indicates the moment of cell membrane penetration, and controlling the grasping force of a microgripper allows accurate characterization of the mechanical properties of a material being manipulated. Recently, force-controlled robotic micromanipulation has found its new application in studying the neuron-level mechanobiology of Drosophila larvae. Specifically, the capability of accurately applying millinewton-level touch stimuli to a Drosophila larva and simultaneously observing resultant fluorescence signal transmissions in its mechanosensitive neurons will enable novel research on mechanisms of the animal's mechanotransductive neural circuitries. The conventional method is to conduct the experiment manually, which is time consuming and requires extensive training for operators. A robotic micromanipulation system designed for this type of experiments could greatly facilitate the mechanobiology research on Drosophila with much higher accuracy, efficiency, and repeatability.In this thesis, a force-controlled robotic micromanipulation system is developed for simultaneously applying accurate mechanical stimuli and quantifying fluorescence neuron transmission signals in Drosophila larvae. The system employs an elastomeric microdevice for immobilizing individual larvae on a substrate, and a microelectromechanical systems (MEMS) piezoresistive force sensor for applying a closed-loop controlled touch stimulus to a larva. A micromanipulator and a microscope XY stage are coordinately servoed using orchestrated position and force control laws for automatic operations. The system performs force-controlled larva touching and fluorescence imaging at a speed of four larvae per minute, with a success rate of 92.5%. A new force control architecture, including a compensation-prediction scheme and a switched fuzzy to proportional-integral-derivative (fuzzy-PID) controller, is also proposed to effectively improve the dynamics of the force control system. The compensation-prediction scheme is employed to accommodate force measurement noise, system modelling errors, time delays and lack of position feedback from the micromanipulator. The switched fuzzy-PID controller is proposed to ensure the fast convergence and small steady-state oscillation of the system. Compared to conventional PID control scheme, the proposed architecture reduces the force overshoot to

Microelectromenchanical systems (MEMS) is a revolutionary field that adapts for new uses a technology already optimized to accomplish a specific set of objectives. The silicon-based integrated circuits process is so highly refined it can produce millions of electrical elements on a single chip and define their critical dimensions to tolerances of 100-billionths of a meter. The MEMS revolution harnesses the integrated circuitry know-how to build working microsystems from micromechanical and microelectronic elements. MEMS is a multidisciplinary field involving challenges and opportunites for electrical, mechanical, chemical, and biomedical engineering as well as physics, biology, and chemistry. As MEMS begin to permeate more and more industrial procedures, society as a whole will be strongly affected because MEMS provide a new design technology that could rival--perhaps surpass--the societal impact of integrated circuits.

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.

Microbiorobotics is a new engineering discipline that inherently involves a multidisciplinary approach (mechanical engineering, cellular biology, mathematical modeling, control systems, synthetic biology, etc). Building robotics system in the micro scale is an engineering task that has resulted in many important applications, ranging from micromanufacturing techniques to cellular manipulation. However, it is also a very challenging engineering task. One of the reasons is because many engineering ideas and principles that are used in larger scales do not scale well to the micro-scale. For example, locomotion principles in a fluid do not function in the same way, and the use of rotational motors is impractical because of the difficulty of building of the required components. Microrobotics is an area that is acknowledged to have massive potential in applications from medicine to manufacturing. This book introduces an inter-disciplinary readership to the toolkit that micro-organisms offer to micro-engineering The design of robots, sensors and actuators faces a range of techology challenges at the micro-scale. This book shows how biological techniques and materials can be used to meet these challenges World-class multi-disciplanry editors and contributors leverage insights from engineering, mathematical modeling and the life sciences – creating a novel toolkit for microrobotics
