4DOF Tendon-Driven Anthropomorphic Wrist: Arduino Mega Robotics Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a robotic hand that can flex, extend, rotate, and deviate just like a human wrist — that’s what you’ll build with this kit. The 4DOF tendon network gives you precise control over four degrees of motion, making it ideal for advanced humanoid robotics, prosthetic research, and complex manipulation tasks.

What You'll Build

A fully articulating wrist joint with onboard force and position sensing, all controlled by Arduino Mega. You'll have a test rig that demonstrates biomimetic motion, ready to integrate into a larger robotic arm or hand project.

What You'll Learn

• Design and implement a tendon-driven actuation system with antagonistic pairs.
• Interface multiple sensors—force-sensitive resistors and magnetic encoders—for real-time feedback.
• Program a PCA9685 driver to coordinate four MG90S servos with sub-degree precision.
• Calibrate and map sensor data to achieve smooth, lifelike wrist movements.
