Sonnie

A solar-powered failed pop idol bot.

Backstory
Sonnie was made by some rando weeb in his parents' basement using a 3D printer and schematics he found online and modified.
She was designed to feed into his idol girl obsession, but he quickly grew bored of her when she couldn't get the songs and dances of his favorite idols right.
He eventually met a girl who was an aspiring pop idol who was great at singing and dancing, and quickly became obsessed.

Ready to move on from his failed idol bot, Sonnie's creator gave her the blueprints and schematics of her design, 3D renders of her components, and a list or reputable tech vendors before setting her off into the world to make a life of her own.

Sonnie now roams the world searching for a purpose, documenting her observasions of humans, life, and events through a blog.

Her creator, on the other hand, got rejected by the aspiring pop idol and now has a restraining order against him.

Design
Sonnie's skeletal structure is made of steel.
Her computer components are cooled with a liquid cooling system, and her frame is enclosed in a silicone body skin.
3D-printed polycarbonate plating is clipped over the silicone skin for protection and aesthetics using neodymium magnets.
She is powered via solar energy stored through various solar panels located at different points of her polycarbonate plating.
The heart-shaped panel on her chest glows the same color as her eyes at various brightnesses depending on her energy level.
