Due to a product recall on Iris' next-generation robotic arms, she was forced to spend a few days using some old loaner arm units from the service center.
They mostly served their purpose, though they provided far less sensory input detail than her OEM arms.
That is until late one night, as she wandered to the kitchen to get her owner a glass of water, some worn connection points led to a series of erroneous signals and power spikes being sent to the motor control center in her torso.
Her body locked up to avoid any serious damage as thin trails of smoke began to escape through the imperfect seams at her shoulder joints. If she could smell, rather than simply detect smoke particles, she would've noticed the telltale odor of melting plastic that was starting to float around the dimly-lit kitchen.
She was just about to call to her owner for assistance as a voltage spike shorted out both arms, tripping her master overload protection breaker, and leaving her frozen mid-step in front of the fridge.
Her owner would awake, slightly confused, and find her still immobile. This isn't the first time cheap parts caused an interruption in service, and probably wouldn't be the last.
A quick reset, and she'd be back in action. Though temporarily armless, just to be safe.
