The history of medical robotics is recent with the first experiments in the field of neurosurgery dating from the 1980s. Important factors relating to its progress have been the rapid evolution of medical imaging technology, as well as in the medical world a growing interest in robotics, which is today a major and practical form of improving medical practice. The recent developments in medical robotics in the last few years have coincided with the arrival of small robots, which are more economical, concentrating on precise indications, in contact with the patient in a way that frees us from the problem of compensating for physiological movement.
