Although robots are not being fully used now in many places, even the United States, they can be used generally to help the medical field worldwide. Due to the increase in diseases and other infections, patients being admitted to the hospital have increased as opposed to the decrease of healthcare workers. In this case, the robots will be of great help. For example, the usage of Nano-robots is to treat cancers. Medical robots include nano-bots, using microscopic robots that can be swallowed like capsule or injected in the blood stream (Kaur, 2014). The job of these robots seems very long but in actual sense, may only take a few minutes. Once the Nano Robot enter the person's blood stream, they can pinpoint and treat diseased cells, bring drugs for the disease and destroy the cancerous cells. The work of a Nano Robot wouldn't stop there, these Robots are able to observe, identify, and repair the patient's body while occupying inside the patient's blood stream. Currently, there are also Artificial Intelligence in voice commands which is normally found on keypads and other applications as well. “This AI-chatbot is used to control electrical appliances using voice commands from Facebook Messenger (New Delhi, 2019).
