## Summary
Sebastian Molano developed TAKTO ONE as his master's thesis at Anhalt University of Applied Sciences. The wearable device uses cable-driven motors to actuate finger joints, with control via a Teensy 4.1 board and feedback from magnetic encoders, IMUs, and a MyoWare 2.0 EMG sensor. The accompanying software includes a VR-ready digital twin and movement recording for playback, with applications in assistive movement and motor learning. Build files are available on GitHub.

## Hardware and software architecture
- **Actuation**: 10 Dynamixel XC330 servos drive cable "tendons" for four fingers and thumb, with two actuated joints per digit (final version; prototype is more limited)
- **Control**: Teensy 4.1 development board manages motors through a servo bus
- **Sensing**: Magnetic encoders for position feedback, IMUs, and MyoWare 2.0 EMG system for muscle activity detection
- **Interface**: Integrated round LCD for status and metrics display
- **Software suite**: Includes VR-capable digital twin simulation and multiple control schemes
- **Movement modes**: Passive finger movement, movement assistance based on detected user intent, and record/playback of motion sequences

## Why it matters
The fully open source release of hardware files and software lowers the barrier for researchers and makers to experiment with assistive robotics and motor learning interfaces, a field typically dominated by proprietary lab equipment.
