In our days industrial robots are indispensable for human society. Humans are dependent to robots because the robots are doing all the hard work for almost all the objects that produced in mass.
Industrial robots have an important role in our days industries because they can do work 24 hours a day and 365 days per year. Industrial robots have helped developing technology in many branches like auto industry, science or aviation and many others.
Even if industrial robots are present in almost any factory that has big production the industrial robots prices are very high because of their capabilities to work 24 hours / day and the profit that these robots can make.
Industrial robots are also important in productions because they are capable to do multiple task and they can be reprogrammed. For example if one auto factory is making a new model of a car doesnt have to get a new robot for that, they can setup their actual robot to make the new car model and that can be applied to all industries.
Small or big companies that require robots for their productions often acquire used industrial robots for their factories because of the low costs and because used robots can be used as new robots.
Some of the well known robot brands that can be bought used are:
ABB used Robots
Kuka used Robots
Fanuc used Robots
Motoman used robots
Used robots are very reliable because industrial robots are built to resist many hours of hard work and also buying and reprogramming a used robots its not so expensive as buying a new robots.
