Builderbots™ are automated construction systems capable of creating raw building materials from the sea floor, primarily glass and metal.
Builderbots™ were invented in 2010 and have since revolutionized construction capabilities at SPL facilities.
The introduction of Builderbots™ led to SPL facilities growing rapidly and amorphously. So far, management has not presented a cohesive expansion plan, so individual researchers have been expanding their living quarters and research spaces at will. Remarkably, nobody seems to have gotten mad about this yet.
Builderbots™ are colloquially referred to as "BBs" by facility personnel.
