The realization of automated chemical experiments by robots unveiled the prelude of artificial intelligent laboratory. Several AI-based systems or robots with specific chemical skills have been demonstrated, but conducting all-round scientific research remains challenging. Here, we present an all-round AI-Chemist equipped with scientific mind that is capable of performing all essential steps required for chemical research. Based on a service platform, the AI-Chemist is able to automatically read the literatures from cloud database and propose experimental plans accordingly. It can control a mobile robot in house or online to automatically execute the complete experimental process on 14 workstations, including synthesis, characterization, and performance test. The experimental data can be simultaneously analyzed by the computational brain of the AI-Chemist through machine learning and Bayesian optimization, allowing to propose new hypothesis for next iteration. The competence of the AI-Chemist has been scrutinized by three different chemical tasks. All-round AI-Chemists with scientific mind may dramatically change the landscape of the chemical laboratory in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
