Preface
Building a robotics system in the microscale is an engineering task that has resulted in many important applications, ranging from microscale assembly 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 into the small world. For example, locomotion principles in fluidic environments do not scale because of the difference in (order of) the Reynolds numbers. The use of rotational motors is also impractical, because of the challenges related to building of the components.
Similar challenges exist in the effort to realize sensing mechanisms. Macroscale positioning techniques such as global satellite ...
