So far, all probes that went to other planets were robotic devices: Pioneer, Voyager, the devices that landed on Mars, etc.
A robotic device can do whatever it's designed to do. There are robotic devices that are designed to paint vehicles in an automobile manufacturing facility, and those robotic devices simply paint vehicles. There are robotic devices that are used to cut metal shapes and others that are designed to cut wooden shapes. There are robotic devices that are used to laser etch, and others that are designed to carve shapes. So far, there are no true "general purpose" robotic devices.
Robotic devices were not "discovered", instead, automation has slowly evolved from simple devices to the computer controlled devices that we have today.
The automobile manufacturing industry uses robotic painting and welding arms. Other manufacturing uses robotic plasma cutters and other robotic devices to assist in precision assembly tasks. Police and military use robotic bomb detonating devices and robotic cameras. Military aircraft are becoming more robotic, for example search information about UAV's Robotic/automated devices are generally manufactured for specific tasks and are generally quite expensive. The autonomous/sentient robot does not exist, although there are a few mechanical toys that appear to emulate a general purpose robot.
they make more accurate incisions
fuse patients’ nerves to robotic limbs
they make incisions that are more accurate.
Some technological devices and tools used in space include spacecraft, such as satellites and rockets, space probes, telescopes, spacesuits, and robotic rovers for planetary exploration. These tools help scientists and astronauts study and navigate space, gather data, communicate, and explore celestial bodies in our universe.
Most robotic devices in the workplace are implemented to increase safety, provide more consistent products and improve production. Often robotic devices make work safer simply by human exposure to minimizing repetitive, potentially hazardous activities.
In the current state of science and medical technology many great things can be done to help people. Some doctors and scientists have discovered how to merge the human body with mechanical or robotic limbs and devices to help people who are amputees or who have lost limbs in accidents. In the future science and medicine will probably develop new ways to integrate the human body with mechanical and robotic devices to make daily life easier.
Hydrogen Peroxide is not directly use to a robot. It is however used along with a robotic devices. Hydrogen Peroxide is dispersed using the robotic device to detoxify hospital bugs.
Output devices are devices which shows us what the computer is processing. Without an output device the computer would do lots of processing but we can't see the results. So yes a robotic arm is an output device.
The website Librarythinkquest contains an educational site on the technology of robotic surgery. The book "Robotic Surgery" by Farid Gharagozloo and Farzad Najam is one of the most important books on robotic surgery. One doesn't need thorough medical knowledge of the subject for understanding the content of the book.
