Not only does this Australian robot negate the need for a lot of illegal immigrant laborers, it also supplies a new, cheaper way to build that southern wall Trump is always yapping about:
This robot apparently does in one hour what a standard bricklayer does in about four. Does it cost more than four bricklayers? Well… probably. But it should be possible to run this thing 24 hours a day, seven days a week, regardless of weather conditions (except for severe storms, of course). And the next prototype is supposed to do what two bricklayers can do in a day… in one hour.
I note, though, a distinct lack of mortar.
