Robotics involves the design, construction and use of robots, machines that can replicate (and usually outperform) human actions. Since their introduction in 1961, they have developed dramatically and have become a core part of advanced industrial processes especially in more advanced countries. They are often viewed both with hope to bring down the costs of more efficient operations and with trepidation with the loss of traditional (especially unskilled) jobs expected due to the automation that they bring (e.g. in automobile assembly). As their skills increase, every sector is expected to be impacted by these, starting with mechanization of several sectors (e.g. agricultural sowing, weeding, harvesting) – which are currently common in the western world but not in many poorer developing countries - that can become more automated with less human involvement. When augmented with more AI, these can also impact many more skilled jobs in the next few years – e.g. translators. The rapidly-evolving concepts of autonomous drones, swarm robots or nanorobots can have several development applications in the real world in the coming years.
