Miniature robots, ranging in size from millimeters to centimeters, have the capability to traverse the various confined pathways inside the human body, including the digestive, urinary, reproductive, and respiratory tracts. These advanced devices promise to enhance or even replace traditional medical interventions, such as those performed with catheters. They are poised to facilitate a range of medical procedures, including minimally invasive surgeries, targeted drug delivery, and live tissue sampling. The adoption of these robotic technologies aims to minimize patient discomfort and enhance the efficiency of diagnostic and therapeutic practices, garnering considerable interest from researchers in the field.
