Arduino-Powered Robotic Hand That Mirrors Your Own in Real Time Kit
Build an Arduino-Powered Robotic Hand That Mirrors Your Own in Real Time
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Have you ever wanted to build a robotic hand that mimics every finger movement of your own hand in real time? This kit brings that ambition to life with 5 flex sensors capturing finger bends and 5 servo motors pulling 15 tendons across five fingers. Perfect for research, advanced hobby projects, or exploring next-gen prosthetics, you'll assemble a fully tendon-driven hand that mirrors your gestures with uncanny precision.
What You'll Build
A fully articulated five-finger robotic hand with independent tendon control for each digit. When you wear the sensor glove (built with the included flex sensors) and bend a finger, the corresponding robotic finger bends simultaneously. The hand can grip objects, form gestures, and respond to your hand's natural motions in real time, demonstrating the principles of robotic kinematics and sensor-actuator control.
What You'll Learn
- Real-time interfacing of multiple flex sensors with Arduino Mega
- Precise servo motor control using PCA9685 I2C driver
- Tendon-driven mechanism design using fishing line and 3D printed hand
- System integration: power management, filtering, and soldering for multi-sensor arrays

Who This Kit Is For
This kit is for advanced makers, B.Tech ECE/EEE/Mechanical final-year students, researchers in robotics or prosthetics, and faculty running labs at NIT/IIT/VIT/BITS. If you're working on a Smart India Hackathon project requiring haptic feedback or gesture mirroring, or a research paper on tendon-driven mechanisms, this kit provides a ready-to-assemble platform.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open an AI companion trained on this exact project. It can answer wiring, code, and debugging questions. For anything else, message us on WhatsApp and we'll respond within hours.
Do I need to 3D print the hand myself?
No, the 3D printed hand is included fully assembled and ready to mount servos and tendons. Just focus on electronics and calibration.
Can I program custom gestures or grip patterns?
Absolutely. The open-source Arduino code is fully modifiable. You can add specific hand poses, automate grip sequences, or even integrate additional sensors.
What tools are required for assembly?
All tools are included: soldering iron, solder wire, and three PCB prototype boards. You only need a computer to program the Arduino Mega.
15-tendon five-finger hand driven by 5 servo motors. Flex sensors mirror operator hand in real time.
