Google Japan has unveiled Gboard Kurukuru Version, a DIY physical keyboard concept that moves keys on conveyor belts so a typist can wait for a character to pass beneath a finger. Google designed it with one-handed or single-finger input in mind, but it is not a retail product, and no published tests show that it is faster, more comfortable, or more productive than a conventional keyboard.
What is Google’s conveyor-belt keyboard?
Gboard Kurukuru Version is a physical keyboard concept announced by Google Japan on October 1, 2026. Instead of keeping keys fixed while a user reaches across a layout, it moves keys toward the user on belts. Google’s announcement describes the idea succinctly: “キーボードの方が動けばよいのです。”—“The keyboard should move instead.” Google’s announcement introduces it as a DIY project, not a new Gboard app feature or a finished commercial keyboard.
How does the moving-key design work?
Each belt carries 29 keys. To enter a character, the user waits for that key to travel beneath a fingertip and times a press. Google says the arrangement can enter uppercase and lowercase characters directly. The central change is mechanical: the keys move, so the user does not have to reach across a stationary layout to find each one.
Google presents one-handed or single-finger typing as the design goal and suggests that two units could be used for two-handed operation. Those are intended use cases, not demonstrated performance outcomes: Google has published no comparative typing-speed, comfort, ergonomic, or productivity results for the concept.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Can you buy it, or build one?
Google says it has no plans to sell the keyboard. It has released open-source project plans, however, and its build guide provides instructions for the motorized Moving Keys Edition. The guide lists a separate Bluetooth Connection Edition as “Coming soon”; that status is not the same as a currently documented build. The Google / mozc-devices project guide is the place to consult for the available build details.
Parts in the Moving Keys Edition
The guide’s bill of materials describes a substantial DIY assembly rather than a ready-to-use keyboard. It specifies:

- 157 3D-printed pieces across 18 component types.
- Four loops made from 29 belt links each, for 116 links total.
- 116 Kailh Choc V1 low-profile switches and 116 matching Choc V1 keycaps.
- One DC 6 V N20 metal gear motor rated at 150 RPM, a DRV8833 motor driver, and an ATOMS3 Lite controller.
- Bearings, fasteners, and the remaining mechanical hardware shown in the guide.
Those figures describe the listed build, not a typing-performance specification. Anyone sourcing parts should match the specified Choc V1 switches and compatible keycaps rather than assuming that other switch profiles will fit.

Not on the evidence available. A conventional keyboard keeps its keys fixed and is a widely available finished product; Kurukuru moves keys and is presented through DIY plans. Its design may interest people exploring one-finger input or unusual keyboard mechanisms, but the moving layout also asks the user to time presses as characters arrive. Without published trials, it is not possible to say whether that trade-off makes typing easier or more effective.

Google says it is considering possible variations, including faster, longer, shorter, and differently colored versions. These are ideas under consideration, not announced releases or guaranteed features. For now, the meaningful distinction is between a documented motorized DIY build and a retail keyboard Google says it does not plan to sell.
