For a long time, robots have been used in the healthcare industry, mostly behind the scenes. In hospitals, the spectrum of robotic applications has significantly increased over the last five years to include helpful applications for doctors, nurses, and patients. In medicine, robots assist by removing routine duties from medical personnel's schedules, allowing them to focus on more important activities, and by making medical treatments safer and less expensive for patients. They can also do precise surgery in small spaces and transport hazardous materials.
