the robots in our modern world are quite amazing. they can do about almost anything that people can imagine. although not everything. but that is what scientists and inventors are aiming for, that robots can one day fulfill any need that a human may want. although there is also a down side to this, for if that were to happen, then we would become lazybums and only robots would do everything for us. in our modern world though this hasn't come yet fortunately. at the moment things that humans have been doing themselves for ages are being doen by robots. this brings great convenience, for it also improves productivity, for example in factories. with robots working in factories, we can be assured that that factory will have a lot more progress and improvement in speed and development, especially compared to a factory from before which didn't use robots.
