Fido

An AI bartender that uses computer vision to decide whether to serve water or alcohol.

Built with two reservoirs, a pump system, and a camera-linked onboard computer, Fido treats the body as input and hydration as output. To receive a drink, users must complete the One-Leg Stand field sobriety test. The project asks what it means to outsource agency to systems designed to “care” on our behalf.

What’s It For?

One more?

Alcohol can make it easier to say yes
and harder to say no.

In a 2015 study on mice, researchers found that repeated alcohol exposure affected two dopamine-sensitive pathways differently.

D1 · Promoting action

Excitatory signals to D1 neurons grew stronger.

D2 · Suppressing competing actions

The same signals to D2 neurons showed no significant change.

So I built a system that decides for you.

Fido uses YOLO, a real-time object detection algorithm, to assess your balance during a one-legged stand test, a standard field sobriety test. Based on your performance, Fido dispenses water or alcohol.

Human agency sits at the edges: you choose to take the test and whether to accept the drink. The system makes the decision in between.

But should it?

How it works.

A reclaimed stainless-steel drinking fountain, hand-polished to a mirror-like shine. Inside, a Raspberry Pi 5 processes HD camera input and controls two diaphragm pumps.

From a balance test to a drink A button press signals the Raspberry Pi to start the HD camera. YOLO on the Raspberry Pi assesses balance while a fan cools the computer. Electronic switches enable only the selected water or alcohol pump. The 12 V DC power supply remains connected; highlighted paths show the active control and load-power routes. A cup fills at the bottom.

Press the button. The camera watches the stand test.

Novel interfaces
invite interaction.

Inspired by Star Wars droids, I designed Fido to feel like a character. Its form and behavior drew viewers into an encounter with embodied AI.

Viewers were generally uneasy about AI making sensitive decisions for them. For me, Fido showed how a novel interface can invite interaction while making questions of care and agency something people can experience firsthand.
