TAKTO ONE is an open-source, wearable hand exoskeleton that measures twelve finger joints with magnetic encoders and can pull fingers with tendon drives. A Teensy 4.1 runs sensing and control locally, while an SD card can record data. TAKTO Lite uses the same sensing approach without the motors.
That makes TAKTO different from camera tracking and flex-sensor gloves: it measures joint angles at the hand, can operate without a computer for its core loop, and exposes build files for experimentation. It is still an experimental research prototype, with incomplete thumb integration and no published validation of force feedback, latency, transparency, or assistance behavior.

What is TAKTO ONE?
TAKTO ONE is a fully actuated hand exoskeleton created and built by Sebastian Molano as a master’s-thesis project at Hochschule Anhalt. The open-source design places magnetic angle sensors at twelve finger joints. Tendons routed through the mechanism move the fingers, and servos provide the pulling force. A Teensy 4.1 development board handles sensor acquisition and the control loop on the wearable system.
The design has two distinct functions:
- Measurement: magnetic encoders report joint angles, while two IMUs and an EMG sensor add motion and muscle-activity signals.
- Actuation: tendon drives and servos can move the fingers for experiments such as teleoperation or assistance.
TAKTO Lite is the sensing-only version. It keeps the twelve encoders, two IMUs, EMG, display, SD-card logging, and live browser, phone, and augmented-reality twins, but omits the motor hardware. Lite is therefore the more practical starting point for motion capture; ONE is the larger research platform for powered experiments.

How TAKTO differs from camera tracking and flex-sensor gloves
A camera system infers a hand skeleton from images. It can be convenient and contact-free, but fingers can disappear behind one another, lighting and background affect the result, and a capture volume or host computer is often needed. A flex-sensor glove measures bending along the glove material; it is portable, but each sensor generally represents an indirect bend measurement that must be calibrated to a wearer and may not isolate every anatomical joint.
TAKTO’s encoders are mounted at the joints, so the device directly measures the angles its mechanism is built around. The trade-off is physical complexity: the user must wear a rigid exoskeleton, assemble and align the mechanism, and manage cables, tendons, power, and safety. Unlike a passive camera or sensing glove, TAKTO ONE is designed to apply motion through its tendons, although the released project does not establish how much force, latency, transparency, or assistance quality it can deliver.
| Capability | TAKTO | Camera hand tracking | Flex-sensor glove |
|---|---|---|---|
| Primary measurement | Joint-mounted magnetic encoders, plus IMUs and EMG | Image-based pose estimate | Sensor bending, interpreted as joint movement |
| Occlusion resistance | Not dependent on optical visibility while worn | Can lose or misread fingers when occluded | Generally unaffected by visual occlusion |
| Capture volume | Not required for the wearable’s sensing loop | Usually needs a camera view and suitable space | Not required |
| Local processing | Teensy 4.1 runs sensing and control on the device | Often relies on a phone or computer | Depends on the glove electronics |
| Actuation or force feedback | Designed for tendon actuation in ONE; behavior is not yet measured | Tracking only unless paired with separate hardware | Usually sensing only |
| Offline logging | Built-in SD-card recording | Depends on the camera application | Depends on the glove |
| Validation maturity | Experimental prototype; current hardware status is documented below | Varies by software and device | Varies by product and calibration |
What data does TAKTO collect, and is it private?
The published TAKTO website states that it uses no cookies, analytics, or trackers. Its camera modes ask for permission before loading third-party content, and camera video remains in the browser. The site also labels generated demonstrations as SIMULATED DATA; the console shows live values only when a real device is connected.

They do not automatically describe an unrelated phone application, cloud dashboard, browser extension, or third-party service that you might connect to the device. If you export files, upload recordings, or route data through another application, that application’s own privacy policy and network behavior become relevant.

What the privacy labels mean
- Simulated data: a demonstration stream generated by the software, not measurements from your hand.
- Live data: values arriving from a connected TAKTO device.
- Camera permission: an explicit browser permission step for the camera-based modes; the published site says video stays in the browser.
- SD-card files: recordings stored on the device until you remove or copy them.
Can TAKTO work without a computer or internet connection?
Yes, for the core hardware loop. The Teensy 4.1 reads the sensors and runs control on the wearable system, and the device can record to its own SD card. A PC is not required for that sensing-and-control path. You still need suitable power, firmware, and a safe hardware setup.
A browser console, phone app, or AR twin can also run with simulated data and therefore can be explored without building hardware. Connecting a real TAKTO is required for live hardware values. An internet connection may be needed to initially load a web application or any content it imports; “offline use” here means local device operation and local recording, not a guarantee that every interface can be installed and launched with no network at all.
Offline workflow
- Assemble and power the Teensy-based device according to the project’s build files.
- Load the released firmware and verify that the sensors report plausible joint positions before attaching motors or wearing the frame.
- Insert a compatible SD card and enable the project’s recording function.
- Run the sensing and control loop locally; the device continues collecting data without a host computer.
- When the test is complete, disable power, remove the card safely, and transfer recordings for analysis on another computer if needed.
The repository reports a default firmware sensor-frame rate of 50 Hz. That is the normal published data frame setting, not a guarantee that every connected application receives 50 samples per second under all conditions.
Does TAKTO work with VR or AR?
TAKTO includes a live “twin” concept for a browser, phone, and augmented-reality display. The documented LUMEN WebXR prototype targets Meta Quest 3S. Its virtual hand is driven by TAKTO’s encoders and IMUs rather than by the headset’s own optical hand-tracking system. In other words, the headset supplies the display and XR environment; the wearable supplies the joint measurements.

- This board DOES NOT feature the Ethernet option

- NXP iMXRT1062 chip, the fastest microcontroller available today

The AR twin can be opened with simulated data for demonstration. To see your own hand motion, connect a real device and use the project’s live-data path. Because LUMEN is described as a prototype, compatibility with other headsets, browsers, controllers, or future WebXR releases should be treated as unconfirmed unless the project documents it separately.
What performance is documented?
Three different rates are easy to confuse, so they should not be treated as one performance number.
| Measurement | Published value | What it describes |
|---|---|---|
| Firmware sensor-frame rate | 50 Hz default | The default rate at which the released firmware produces sensor frames. |
| Browser console display rate | 60 Hz | How often the browser console refreshes its display, not necessarily the sensor sampling rate. |
| On-device control loop | Up to 2 kHz | The maximum documented execution rate for the local control loop. |
| Maximum encoder sampling rate | Not characterized | It depends on the I²C bus and multiplexer switching. |
The project does not publish measured force-rendering capability, end-to-end latency, mechanical transparency, or assistance behavior. A 2 kHz control-loop ceiling therefore cannot be read as a 2 kHz user-data stream or as proof of low-latency force feedback. Actual results will depend on the bus, firmware settings, mechanical load, servo configuration, and the application receiving the data.

How much does it cost to build?
The project repository’s 2026 parts figures provide a starting point, not a guaranteed finished-device price. They are best read as the priced components listed by the project; labor, tools, shipping, taxes, substitutions, failed prints, and locally unavailable parts can change the total.
| Build or order | Published amount | Qualification |
|---|---|---|
| TAKTO Lite | EUR 164.48 | Priced parts total listed by the project in 2026. |
| TAKTO ONE | EUR 1,222.25 | Priced parts total listed by the project in 2026 for the actuated design. |
| Two-board JLCPCB order | USD 170.73 | Amount documented for that specific two-board order; it is not a universal PCB price. |
The named controller is a Teensy 4.1. Other directly relevant components include AS5600 magnetic angle sensors and a MyoWare 2.0 EMG sensor with disposable Ag/AgCl electrodes. The full ONE design adds eight servos and tendon hardware; Lite omits the motor system. Before ordering, check the current bill of materials, regional stock, board revision, connector choice, and whether a quoted amount includes shipping or assembly.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you try TAKTO without building it?
Yes, but only the software demonstrations and simulated streams. A practical first session is:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Open the published TAKTO web interface in a compatible browser.
- Choose the browser console, phone view, or AR twin described by the project.
- Confirm that the interface identifies the stream as
SIMULATED DATA. - Exercise the visualizations and verify that no claim of live sensing is being inferred from the animation.
- For live data, connect a correctly assembled and powered TAKTO device; the console should then display hardware values rather than simulated values.
This software-first route is useful for checking whether your browser or phone can render the interface and whether the data format fits your project. It does not test encoder accuracy, mechanical comfort, servo torque, or real-time latency.

Is TAKTO a medical device or protective product?
No. The project explicitly states: “TAKTO ONE is an experimental research prototype. It is not a medical device and not a certified protective product. Do not use it for diagnosis, treatment, unsupervised rehabilitation, or safety-critical operation.”
That warning rules out using the exoskeleton as a clinical therapy device, a diagnostic instrument, or protective equipment. A research prototype can be valuable for investigating interfaces and control methods without meeting the testing, risk management, reliability, and regulatory requirements expected of a medical or safety-certified product.
Safety checklist before powering or wearing it
Motorized tendons can pinch skin, overextend joints, or move unexpectedly. Follow the project’s recommended precautions and add a conservative test plan:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Install a separate motor-power cutoff that can remove actuator power immediately.
- Start with torque disabled and verify that startup cannot command motion unexpectedly.
- Test away from the body before placing the mechanism on a hand.
- Check every mechanical limit, tendon path, fastener, and sensor reading at low risk.
- Perform watchdog and fault testing so a disconnected sensor or stalled controller does not create an unsafe command.
- Keep the thumb unactuated if your build matches the reported status in which it is not yet fitted.
- Do not conduct unsupervised rehabilitation, diagnosis, treatment, or safety-critical experiments.
Which TAKTO version should you choose?
Choose TAKTO Lite for sensing and motion capture
Lite avoids the cost and risk of motors while retaining the twelve encoders, IMUs, EMG, display, SD logging, and software twins. It is the sensible entry point if your goal is recording hand movement, developing visualization, or testing an offline data pipeline.
Choose TAKTO ONE for actuation research
ONE is intended for experiments that need tendon-driven motion, teleoperation, or assistance concepts. It requires the larger parts budget, servo integration, careful mechanical-limit testing, and a willingness to work with an incomplete prototype whose force and latency characteristics are not yet measured.
Bottom line
TAKTO is a locally controlled, open-source hand-tracking platform with unusually direct joint sensing and an offline logging path. Its strongest documented use is experimental motion capture and interface research: the Teensy handles the core loop, simulated twins let you explore the software without hardware, and the wearable can record to an SD card. TAKTO ONE adds experimental actuation, but its incomplete thumb integration and unmeasured force, latency, transparency, and assistance behavior mean it should be treated as a research build—not a finished consumer, medical, or safety product.
