## Introduction Research teams from the University of Pennsylvania and the University of Michigan have developed fully programmable, autonomous robots 'smaller than a grain of salt'. Researchers expect these new micron-scale robots to be used in medicine, microscale manufacturing, and other areas. ## Technology The robots were designed to be completely programmable and autonomous. They are intended for use in fields such as medicine, manufacturing, and other applications. ## Implications The use of these robots could revolutionize the way we tackle complex problems. They may be used to perform surgical procedures with incredible precision, monitor patients, and provide remote assistance. ## Future prospects Researchers hope that these robots can be used in many other areas, such as electronic component production and data analysis. The possibility of developing new applications is vast and promising. ## Conclusion The creation of autonomous robots smaller than a grain of salt represents an important step towards the development of more advanced technologies. We hope that this innovative development will have a positive impact on our daily lives.
