First of all, we have to think that everything a robot does is what human programmed it to do. This technology will develop every day, but only man will control everything.
Aristotle once said that only if there were tools working independently then there would be equality between people, an idea we embrace and we like to believe that someday this world could change.(1)
There are many projects that people are working at like fully autonomous heavy robots, agricultural robots, robots that can take care of old people, nanorobots and more.(2)
