This book presents research-backed examples of how robots are being employed to assist healthcare procedures. This becomes pertinent with repeated pandemic outbreaks. The COVID-19 pandemic has necessitated "social distancing" with robust sterilization and cleaning procedures: robots have been probed in these aspects. The book starts with examples of robots in healthcare followed by two chapters on surgical robots or case studies and examples of the potential of these machines in surgery. The concepts of nano and micro have been extended to robots with the development of "nanobots". Research is ongoing in this field aimed at employing these robots to target specific cells or deliver appropriate cargo to alter the face of drug delivery.
