Simone Giertz, the self-described queen of bad robots, has created a selfie booth out of Lego for her dog scraps. It helps that the dog is a very good girl and extremely photogenic.

Giertz used a Lego Mindstorms kit and Lego bricks to build the little booth. Rigged a pedal, distance sensor and circuit board to connect to a dispenser that drops a treat. The video is sponsored by LEGO.

‘she gets a treat, I get a photo, everyone’s happy,’ says Giertz.’it triggers a camera that triggers a treat dispenser,’ Giertz says.

She got the idea for the dog photo booth when she was trying to teach scraps to scroll on a phone with her paw and take photos of herself.

Giertz is known for her quirky, mostly useless robots that rarely do what they’re supposed to but which are completely hilarious. Witness the overzealous lipstick-applying robot, the breakfast machine that gets Cheerios everywhere but into the bowl, the musical instrument made of teeth, and the wake-up machine that features a rubber hand slapping her awake.
