I. Pre-Programmed (Medical) Robots

Pre-programmed medical robots are ones that have to be told ahead of time what to do, and then they simply execute that program. They cannot change their behavior while they are working, and no human is guiding their actions.

Pre-programmed robots are particularly good for tasks that require a very high level of accuracy at a very fine level. For example, if we want to use radiation to kill tumors in cancer patients, we need to be able to deliver the radiation precisely to the tumor. If we miss, we may end up killing healthy tissue near the tumor instead of the tumor itself. The CyberKnife radiosurgery machine is a pre-programmed robot designed to deliver very precise doses of radiation to very precise locations within the human body.

Another common use of pre-programmed robots is as training simulations, such as the S575 Noelle. These robots are constructed to present medical students with various scenarios that they must diagnose and treat. The robot is pre-programmed with a possible scenario, and its responses to the students' treatment is also pre-programmed. So you could not, for example, try an experimental treatment because the robot would not know how to respond. You must try one of the treatments that the robot is programmed to respond to.
