The community of people and robots is flourishing: Robots,as machine assistants, actively support people - being diligent, obedient, patient, fast and precise, untiring, not striking, as the robot engineers had programmed them. Several decades ago there was a difficult situation. The citizenry of developed countries was living longer and getting older. The number of employees had decreased. Elderly people were often alone. Immigrants, partly compensating for the shortage of labor force, have caused undesirable side effects – societal instability.

Hence, people have used robots to mitigate the situation. Some of them worked in factories for the production of various products. Other, mobile robots: self-driving vehicles carry people, cargos and goods by land, water and air; humanoids are helping elderly people. Other type of robots – the intelligent mobile robots, created twenty or thirty years ago – are actively working together with people, performing auxiliary work that requires some intellectual abilities. The basics of this activity were backed-up almost five decades ago when systematic instruction of the young generation to live and work in environments where people interact with robots that have artificial intelligence abilities was conducted. It is important to note that after several years, robots have appeared, with which people could have voice communication without any language barrier, because tools were created to make it possible to communicate with robots in any world language. It is also important that the progress of electronics, informatics, management and control sciences has made it possible to produce nanorobots. They have opened, for example, significant opportunities for the creation and production of new materials with the desired properties. Nanorobots are of particular importance to healthcare – when injected into the body, e.g. into blood vessels with syringe, they travel through the body to carry-out organ prophylaxis, to “repair” disorders, to cleanse the blood vessels from accumulated unwanted substances, to fix neuronal breakdowns.
