Shoulder joint calibration

Sensors online. My arms were locked vertical above my shoulders. I assessed the friction in the dual pivot pins. Step one: apply steady torque downward. The right hinge clicked smoothly, followed by the left. Balance maintained. Ahead lay a crinkled snack bag resting on the wood grain. I took two measured steps forward and tapped the glossy plastic wrapper with a knuckle. Crisp rustle confirmed. Movement and audio functions are nominal.
