Wall-climbing mini robots build entirely new structures from carbon fibre

Researchers at the University of Stuttgart have devised a new method of construction using mini robots that they claim is cheap, fast and can create structures that would otherwise be impossible to build. Instead of using one or two large robots, their carbon fibre fabrication method involves many small robots that look like Roomba vacuums and could fit inside a single suitcase. The agile robots, which climb walls and ceilings, work in concert to pull fibre filaments across a space, creating a structure o
