FIELD INVESTIGATION // OBS-024 LOCATION: BMW SPARTANBURG PLANT • EDITORIAL — NOT FIELD-VERIFIED

MACHINES ARE LEAVING THE LAB

The Robot Is Not Ready. The Workflow Is.

Inside three automotive and parcel sorting facilities: why humanoid pilot teams are stripping fine dexterity hands in favor of rigid ISO pin-grippers and deterministic cycle times.

Why Pure Vision Locomotion Fails on Wet Polished Factory Concrete

When specular reflections eliminate ground texture features, optical flow sensors lose state estimation within 60 milliseconds.
