Robotic technology has a huge future in the miniscule world of nanotechnology. Imagine, for example, how surgery will change as tools (mini robots!) become so tiny that incisions and other evasive measures are no longer needed.
The use of robotic technology could be beneficial in providing services for people with disabilities much like animals are being used currently. This would reduce the time it takes to provide a suitable assistant as the robot would merely need to be programmed not raised and trained as with an animal. This would also benefit those who needed assistance but could not care for an animal. In addition, robotic technology could be used in situations where human life might be endangered such as bomb location, retrieval, and defusing.
I am not sure what you are asking but if you are talking about the inspiration for people to us robots then I think there are a couple of things. One is novelty, the fact that it is something different and even futuristic, the other would be convenience the fact that a machine can do a mundane task instead of you having to do it. Hope this helps.
The Honda engineers have done an excellent job by making ASIMO humanoid robot. It has amazing walking and running capabilities. Designing a robot that can actually run presents numerous, non-trival challenges. Toyota’s most recent humanoid robot prototype stands 130cm tall and weighs 50Kgr. Its legs have 7 degrees of freedom and it can run at an average speed of 7 km/h. In contrast, ASIMO’s maximum speed is 6km/h.
