there are many factors that limit the rapid development of service robots, among which the main reason is that the development speed of related high-tech can't keep up. Wood John, a senior American professor, pointed out that biotechnology, intelligent robot technology, nanotechnology and supercomputer technology have the greatest influence on the development of service robots in the future, and these technologies will determine the update and development speed of service robots. It can be said with certainty that if the future service robots want to serve human beings more intelligently, they must face these core technical problems.

In addition to related technical factors, there are also some reasons that indirectly affect the development speed of service robots, such as the concept of consumers and the ethical research on service robots. The survey shows that some people are psychologically unacceptable to the high price of service robots at present, and they are more skeptical about service robots. They think that service robots can only do some simple and mechanical actions, but they can't deal with emergencies flexibly and efficiently like humans. At the same time, the rights and responsibilities of intelligent robots have not been effectively solved, such as the controversy caused by robot killings in Japan and the accountability problems caused by innocent casualties caused by military service robots. If these non-technical problems are not solved reasonably, they will also restrict the rapid development of service robots in the future.
