One-touch folding

Five seconds. One touch.
Nothing to take apart.

Smart wheelchairs carry sensors and computers, and most of them have to come apart before they fit in a car or a closet. CIHANG folds as one piece. Seat, LiDAR, cameras, display and computers stay exactly where they are. Press once, and it drops from 880 mm to 510 mm.

Designed for the living room

It looks like furniture.
That's the point.

Powered wheelchairs tend to arrive in black and white, with the machinery on show. CIHANG was co-designed with older adults to be something you would keep in the living room: a low, stable stance, rounded surfaces that wrap around the technical parts, warm low-saturation colors, and solid walnut where your hands rest.

Nothing exposed, nothing clinical. Sensors, batteries and actuators sit inside one continuous shell.

  • IP54 enclosureWipe it down without a second thought.

On-device voice AI

Just say where
you want to go.

CIHANG runs a language model on its own onboard computer. Your voice never leaves the chair, and it keeps working when the Wi-Fi doesn't. It understands more than 61 Chinese dialects, heavy accents and slower speech, so you talk to it the way you already talk.

Listening · on-device
Take me to the kitchen.
On my way. I'll go around the coffee table.
A bit slower.
Slowing down.
I'm done. Go charge.
Heading back to the dock.

Works offline

Speech recognition and the language model run locally. No cloud, no account, no waiting for a server.

Private by design

Nothing you say is uploaded. The microphone feeds the chair, not a data center.

61+ dialects

Built for regional dialects, varied accents and slower speech, and for people who change how they talk from day to day.

Still yours to drive

Voice sits alongside the joystick, touchscreen, gesture and app control. Use whichever is easier today.

Autonomous navigation

It maps your home
on the first drive.

Two LiDARs and two depth cameras scan every room, doorway and threshold as CIHANG moves, and build the map on the spot. From then on it plans its own route, steers around people, pets and furniture in real time, and returns to its dock when the battery runs low. Try it below: scroll to watch the first drive build the map, tap a room or tell the app where to go, or take the joystick and drive it yourself.

Perception & drive

Two LiDARs. Two cameras.
Two computers.

Dual RGB-D cameras
Depth and terrain data, fused with LiDAR.
SLAM + ROS 2 Nav2
Proprietary map optimization, localization and path planning. Obstacles handled in under 200 ms.
Dual-system architecture

Who it’s for

Built for people who still
have places to be.

For anyone who finds walking hard for a while, or for good, and for the people who look after them. Four situations we designed around.

A day with CIHANG.

A grandmother in a CIHANG on a park lawn, handing a strawberry to her granddaughter; the family on a picnic blanket beside her
Out with the family. Lawn, path or picnic blanket, the chair comes along — and three generations share the afternoon.
  1. “I’m thirsty.”To the kitchen. No hands on the joystick.

  2. Doorbell.“Someone’s at the door” takes it to the entry.

  3. Out to the park.Folds in five seconds, into the trunk as one piece.
    Recovering
  4. “I’m tired.”Bedroom for a nap. The app shows the family it arrived.
    Caring from a distance
  5. Dinner.Dining table, then the sofa for the evening news.

  6. Back to dock.Charges overnight. Ready by morning.

And where one chair serves many.

Hospitals and rehab. Ward-to-clinic transport, elevators handled by the chair, remote locking from the nurses’ station. Staff walk less; patients wait less.
Two residents having tea in a senior community lounge, one seated in a CIHANG; a second chair charging by the wall
Senior communities. One fleet, many residents. User switching, a saved place for everyone, docks in the lounge. Independence across the whole building, not just the room.

Rental fleets and hospitality. Malls, airports, parks, resorts. Rent from a dock, return anywhere, and fleet management sees every chair, every charge and every trip.

FAQ

Questions.

Does it need an internet connection?

No. Voice, navigation and mapping run on the chair's own computers. A connection adds app features such as remote monitoring, elevator calling and software updates.

How small does it get?

Folded, CIHANG is 510 mm tall, down from 880 mm. It stands in a wardrobe, lies flat in a car trunk and fits in equipment rooms and elevators without disassembly.

Can I still drive it myself?

Yes. Use the joystick, touchscreen, gestures or the app at any time. Release the joystick and the chair stops. Autonomous driving is a mode you switch into, never something forced on you.

Who is it for?

Older adults who want to keep living at home, people recovering from surgery or injury, long-term wheelchair users, and the families who support them. Care homes, hospitals and rental operators use the Shared version. See the four situations we designed around.

Is it certified?

CIHANG is registered as a Class II medical device with the NMPA and tested to GB/T 12996-2024 and GB/T 18029 / ISO 7176 for wheelchair safety, stability, braking, fatigue durability and EMC. Additional certifications include EU CE (MDR and RoHS), U.S. FDA 510(k) and FCC, Korea KC and MFDS, and UN38.3 battery transport testing.

How do I buy one?

The personal version is sold direct to consumers online. The shared version is available to institutions through WDC Robot.
