This reminds me of swarm robotics, which have a similar approach to scale. And an approach that cooperated towards a goal.
Why Spider Robots Could Be The Next Big Thing In 3-D Printing
By Jason Compton
Three-dimensional printing has long had a serious limitation: You can’t make an object larger than the print bed. Consequently, 3-D printers for large-scale objects have taken up a lot of space and required a lot of heavy machinery to move the nozzle around.
Taking a cue from nature, technicians at Siemens may have solved the problem. Instead of building a bigger, better 3-D printer, the company has designed compact “spider robots” that work together to weave large objects seemingly from thin air. .... "
