Abstract：Robots and public libraries The Fourth Industrial Revolution now includes the emergence of artificial intelligenceAIand automated roboticsXu et al2018This revolution is disrupting and changing the entire landscape of education and industryShahroom and Hussin2018Humanoid service robots are being used in sectors of industries all over the worldNguyen2020Howeverhow these humanoid robots might be integrated into the library sectoras well as the potential ethicalprivacylegal implicationsis currently under investigationSome academics believe that highly intelligent humanoid robots may face ethical and moral quandariesOther issues to consider include whether humanoid robots can be considered legal persons capable of assuming legal obligations and how robots and humans can co-exist in the same environmentTella2020noted that AI in humanoid robots is already available in libraries in both developed and developing countrieswhich is no longer newsThe robots engage in activities such as scramblingrollingsoaring and climbingThese robots have an impact on libraries and the larger informationand socialenvironment in which we all liveLibraries have recently begun to provide access to robots and robot-related science technologyengineering and mathematicsSTEMeducation programsWestportConnLibraryfor exampleoffers training for its two programmablehumanoid small humanoid robotNAOrobotsand the Chicago Public Library lends smallmobile Finch robotsThe University of Rhode Island LibrariesAI Lab hosts weeklyrobot hoursduring which students learn to control and program robotsSome aspects of library work are more likely than others to benefit from robotsAccording to Kim2017libraries can use humanoid robots to greet visitors and provide directionsLibbya robot at the University of Pretoria Libraries in South Africaalready performs such tasksAs AI in humanoid robots improvedsuch as the ability to identify and re-shelve misfiled booksthey became more useful for library access servicesRobots can also assist with reference requestsparticularly simple onesThese robots can be online chatbotsBlut et al2021To provide basic reference servicesthe University of Oklahoma Libraries is experimenting with AlexaAmazons virtual assistantSimilarlyreadersadvisory robots can be usedand childrens librarians may find reading robots usefulWhen robots interact directly with library patrons and staffsafety may be an issueVillani et al2018Interacting with robotson the other handcan strengthen those bondsMore sophisticatedversatile and autonomous robots are likely to enter our homesworkplaces and libraries as AI technology advancesNobody knows how the widespread use of robots will affect librariesbut it will undoubtedly raise a slew of intriguing questionsQ1Are libraries equipped to house AI-powered humanoid robotsQ2Can the implementation of these robots improve reference services or pose a threatLibrary AutomationThese robots have the ability to identify and re-place wrong bookswhich means that they can be used for library automationConsulting ServiceRobots can answer reference requestsespecially simple requestsFor examplethe library of the University of Oklahoma is experimenting with Amazons virtual assistant Alexa with basic reference servicesRetrieval and IndexingRobots can be used to greet visitors and provide guidelineswhich means they can help visitors find and index informationThis article focuses on the application of human-type robots in the libraryThese robots can perform a variety of taskssuch as greeting visitorsproviding guidelinesidentificationand re-placing wrong booksand answering reference requestsIn additionrobots can be used as an online chat robot to provide basic reference services
