Actuated Clothes Hanger

A shape-changing clothes hanger that reacts to how much attention you give your clothes.

⌗ Overview

Clothes that go unworn tend to disappear from our attention entirely. There's no feedback loop to notice what's being neglected.

This project turns an ordinary hanger into a closet companion — an object that waves, gets excited, and even droops based on how often its clothes are worn. Instead of a screen or a notification telling you "you haven't worn this in three weeks," the hanger itself changes its posture and behavior to make that neglect physically visible.

⌗ Concept

Catching Your Eye

As you browse the closet deciding what to wear, the hanger waves to draw your attention — a quiet nudge toward clothes you might otherwise pass over.

Excitement on Pickup

The moment you take it off the rack, the hanger spins with a burst of vibration, creating a small, satisfying reaction that rewards the choice.

Drooping from Neglect

Left untouched for too long, the hanger slowly droops to one side, its posture sagging as if the clothes themselves are giving up — making neglect something you can see, not just forget.

⌗ Assembly

⌗ CAD Model

⌗ Schematics

Microcontroller: Seeed XIAO ESP32C3

Sensing: HLK-LD2420 24GHz mmWave radar (UART) for presence and distance detection

Haptics: DRV2605L driver (I2C) driving an LRA vibration motor

Actuation: 5 servos total

  • 1× MG996R for full hanger rotation

  • 4× SG90 for shoulder joints and scissor-mechanism linkages


⌗ Future work

Add a spring-and-pulley driven "neck" to enable extension / contraction motions like a sudden jump or bounce

Integrate an IMU to detect pick-up and put-down events, enabling longer-term tracking of usage patterns and decision-making
