Abstract	For the High-Luminosity Large Hadron Collider, the ATLAS experiment will replace its current Inner Detector with an all-silicon Inner Tracker (ITk), consisting of pixel and strip systems. In the end-cap, silicon sensor modules of the strip system are mounted onto support structures called "petals". To facilitate the assembly of petals, an automated system has been developed which streamlines the production process and ensures uniformity. This paper presents the latest results from the assembly of the first ITk pre-production petals, including characterization of their electrical performance and studies of their robustness at very cold ($\leq -35\,^\circ\textrm{C}$) temperatures.
