Microrobots are autonomous miniature robots whose size is smaller than one millimeter and which are used in medicine. Such intelligent and autonomous micro-robots can actively travel through the human body, even to areas of the body that are difficult to access or inaccessible.
The use of microrobots is minimally invasive and is done without causing much harm to the patient. As with other minimally invasive procedures such as endoscopy or cardiac catheterization, mini-robots are inserted into veins. Because they are autonomous and have no cable connection, they can navigate independently through the human body and use built-in sensors to collect and transmit measurements. Microrobots must be able to adapt and change constantly.
In order to realize the high complexity of a microrobot, developments are based on the structure of bacteria.
