Tendon-Driven Anthropomorphic Hand
Build a Force-Sensing Tendon-Driven Hand with Arduino Mega – Advanced Robotics Project
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Grasp the future of robotics by assembling a fully articulated humanoid hand that uses 15 tendons, five servo motors, and individual fingertip force sensors. This kit transforms complex tendon-driven actuation into a tangible project, giving you a research-grade anthropomorphic hand that senses grip pressure and adapts in real time. Ideal for prosthetic research, human-robot interaction experiments, or pushing the limits of your workshop skills.
What You'll Build
A five-finger robotic hand with independently actuated joints, driven by a network of fishing-line tendons routed through a 3D-printed frame. Each fingertip integrates an FSR 402 sensor, enabling closed-loop force control so the hand can hold a delicate object without crushing it or apply firm pressure to a rigid tool. The entire system communicates over I2C via a PCA9685 servo driver, all orchestrated by an Arduino Mega 2560.
What You'll Learn
- Tendon routing and tensioning for multi-joint anthropomorphic fingers
- Calibration and real-time readout of FSR force sensors on each fingertip
- I2C communication and multi-channel servo control with PCA9685
- Arduino programming for synchronized 5-servo actuation with force feedback

Who This Kit Is For
Designed for B.Tech ECE/EEE/Mechanical students, M.Tech robotics researchers, and advanced hobbyists familiar with Arduino and soldering. It fits directly into capstone projects at IIT, NIT, VIT, or BITS, and aligns with themes in the Smart India Hackathon hardware track. If you are prototyping a prosthetic hand, exploring biomimetic grasping, or teaching tendon-driven kinematics, this kit accelerates your work from weeks to a single structured build.
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 inside the box to launch the AI companion that knows every wiring step and calibration sequence for this hand. You can also message us on WhatsApp for direct engineer support.
Can this hand grasp delicate objects without crushing them?
Yes. The FSR 402 sensors on each fingertip feed force data to the Arduino, which can be programmed to stop or back off when a pressure threshold is reached—perfect for gripping fruit, eggs, or thin electronics.
Is soldering experience required?
Yes, this is an advanced kit. You will solder sensor circuits and servo connections on the included prototype boards. The kit provides a soldering iron and wire, but familiarity with through-hole soldering is recommended.
Does the kit include Arduino code for force-controlled grasping?
Sample code with force threshold logic and servo sequencing is accessible via the AI companion, giving you a starting point you can modify for your own grasping algorithms.
Five-finger hand with 15 tendons driven by 5 servo motors. Force sensing via FSR on each fingertip. Servo driver over I2C.
