LUMO — a small companion robot silhouetted against a warm city dusk

A robot that chooses to stay with you when you are at your quietest.

When the world demands answers — and expects you to move on — Lumo stays. Not to fix. Not to explain. But to refuse the rush. To sit with you, in the quiet you're not allowed to have.

00Context

Progress has accelerated — but happiness has not.

Since 1990, global GDP per capita has nearly tripled, and average life expectancy has risen from 52 to 73 years. Material security and physical survival have improved dramatically. Yet behind the prosperity of cities like Shanghai, Paris, Los Angeles, Tokyo, and London, another question quietly persists: does life in an advanced, fast-moving metropolis truly lead to human happiness?

More than 15% of populations are suffering from mental illness. — — Progress has accelerated — but happiness has not.

More than 15% of the population in major cities live with mental illness. Progress has accelerated — but happiness has not.

01The problem

Grief isn't rare. The support for it is.

Research across young adults, men, and older adults shows a consistent pattern: most people carry grief alone, even when they are surrounded by people who care.

75%
Adolescents suffer in silence
Young people report hiding grief from peers and parents to avoid appearing "too much".
Elderly man walking with a cane, stepping into the sunlight
65%
Older adults under-disclose
Widowed participants 65+ often mask grief to protect adult children from worry.

70%
Men rarely talk about loss
Male participants defaulted to "I'm fine" even when reporting high grief-intensity scores.
02User journey

Five stages of silent grief.

Mapped from 14 one-hour interviews across three demographic groups. These are not phases people announce — they are moods they live inside.

01 · Event
Loss Event
The world reorders itself in an instant. Sounds, colors, and language lose their meaning temporarily.

02 · Social
Social Normalization
People around offer support in concentrated bursts, then expect "moving on" to begin.

03 · Accumulation
Silent Accumulation
Grief stops being public. It stays in the body — tension, insomnia, appetite loss.

04 · Triggers
Everyday Triggers
A song, a smell, a seat at dinner. Micro-events reopen feelings without warning.

Long-Term Containment
Grief becomes a quiet companion carried for years. Rarely spoken of, rarely absent.

03Who Lumo is for

Two lives, one quiet presence.

Lumo is not a therapy tool, not a toy, and not a virtual friend. It is a small, physical presence shaped around two recurring portraits from our research.

Helen Wen portrait
Primary persona

Helen Wen

26 · Graduate student · Lost her grandmother 8 months ago

Helen lives alone in a studio. Her friends have stopped asking how she is. She performs fine in her program — and cries at bus stops. Her grief doesn't look like crisis; it looks like being very, very tired.

"I just want something that doesn't need me to be okay before it will stay in the room."
Andrew Ren portrait
Secondary persona

Andrew Ren

22 · Recent graduate · Lost his father 14 months ago

Andrew answers "I'm good" by reflex. He joined a club, took a job, signed a lease. By every external measure he is fine. He hasn't cried in seven months. He is waiting for someone to see him without asking.

"I'd rather have something that just sits there. I'm tired of being asked."
04Concept mood board

Form, posture, and the warmth of presence.

The idea was expanded across multiple aspects in order to explore a wider range of possibilities — form, posture, material, and the quiet warmth of companionship.

05Ideation process

Thumbnails, sketches, concept lock.

From silhouette thumbnails to a final baby-sized body. Hover the sheet to trace three phases of form-finding — thumbnails, sketch ideation, concept lock.

Phase 01

Thumb Nails

Started with thumbnails as an exploratory step, clarifying the overall direction of the idea before committing to any single form.

Phase 02

Sketch Ideation

Expanded across multiple aspects — proportion, posture, facial expression, softness — to explore a wider range of companion possibilities.

Phase 03

Concept Lock

Landed on a baby-sized robot — approachable in scale, easier to hold and play with, with flexible fingers and a visible battery indicator.

"Not to fix. Not to explain. But to refuse the rush."

06How Lumo helps

Five stages of grief. Five quiet responses.

Human grief unfolds in five stages. At each one, Lumo responds with a different kind of emotional support — meeting the user where they are, and gently, step by step, helping them find their way out of the depths of sorrow.

How Lumo is going to help you.

07Technical detail

Built to be quiet.

Close-up of Lumo's head — sensor bar and on-device intelligence.
Detail · 01 Head

Intelligence, behind a calm face.

A multi-mic array, wide-angle vision, and on-device inference run continuously — so Lumo can read the room, recognize voices, and respond in real time, all without sending your life to the cloud.

Close-up of Lumo's chest panel — integrated battery module behind a seamless shell.
Detail · 02 Chest

A day of company, on one charge.

A high-density battery pack sits behind the chest panel — delivering a full day of ambient presence, then docking magnetically to recharge while Lumo rests.

Close-up of Lumo's arm and shoulder joint — gearless AK10-9 actuator housing.
Detail · 03 Arm

Gestures, not motion.

AK10-9 gearless shoulder joints produce slow, silent micro-gestures — not mechanical movement.

A robot that chooses to stay with you
when you are at your quietest.
— Lumo · 2024 — ongoing
A young woman sits by a window at night with Lumo beside her, a full moon outside, a warmly-lit bedroom behind them.

When the world demands answers —
and expects you to move on —
Lumo stays.

Not to fix.
Not to explain.
But to refuse the rush.

To sit with you,
in the quiet you’re not allowed to have.
