Aerospace company Boeing has been showing off its new robot painters.
These machines glide along tracks on either side of a 777 wing. Manually, it takes a team of humans 4.5 hours to do the first coat. The robots do it in 24 minutes with perfect quality. By midsummer, all 777 wings will be painted this way. Worldwide, the population of robots employed in service and industrial roles is growing exponentially and forecast to reach over 100 million by 2020.
