A dragline-forming mobile robot inspired by spiders
Elongation of newly extruded material is caused by the tensile stress when the two wheels pull the structure they hold, e.g. the already formed part of dragline , away from the nozzle.

Primary structure elements of spider dragline silks and their contribution to protein solubility.
Repetitive regions representing the largest part of dragline silk proteins determined the solubility of the synthetic proteins, which differed greatly between constructs derived from ADF-3 and ADF-4.
