Robotic arms, like many other digital fabrication tools, are getting increasingly accessible but these ones have more potential than the others (3D printing, laser-cutting, CNC..etc) as it can do all of it and more. It can cut, print in 3D or even fold!
Below are couple examples of Robots being use to fold, print or fabricate components which could be used as building block.
First, lets start with London, ROBOFOLD offers workshops, and rents out their large 6 axis Robotic Arms which are mainly use for Folding Metal sheets.

In Vienna, Robots in Architecture is an association set up by Johannes Braumann and Sigrid Brell-Cokcan which owork with a KUKA KR 5 SIXX R650 Robotic Arm to draw or punch holes. They also use Grasshopper but with the KUKA plugin. Below are couple images shown on their website:
