Gesture-Controlled Robotic Hand Kit with Flex Sensors & Arduino Nano

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

This kit puts the future of teleoperation on your workbench: a glove fitted with five flex sensors captures every finger movement, then transmits the angles wirelessly to a servo-driven robotic hand that copies you in real time. Whether you are prototyping a sign language interpreter, demonstrating remote manipulation for a hackathon, or investigating haptic feedback loops, you'll walk away with a fully functional, bidirectional hand-mirroring system that can be extended with force feedback, IMU wrist tracking, or computer vision.

What You'll Build

You'll assemble a wearable glove that bends five 2.2-inch flex sensors across the fingers, converting curvature into voltage. An Arduino Nano on the glove reads the analog values, maps them to servo angles, and streams the data over an HC-05 Bluetooth link. A second Nano on the receiver drives five SG90 micro servos attached to a hand replica (cardboard or 3D-printed) via fishing line tendons. When you curl your index finger, the matching servo pulls to exactly the same degree-instantly. The system can also transmit raw sensor data to a PC for Python visualization, making it a robust platform for academic research and innovation challenges.

What You'll Learn

• Calibrate five flex sensors for linear, repeatable angle output over a full finger range
• Establish reliable Bluetooth serial communication between two Arduino Nanos
• Drive multiple SG90 servos in real time using software PWM and angle mapping
• Troubleshoot a wearable mechatronic system-signal noise, power distribution, and mechanical slack

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for final-year B.Tech students in ECE, EEE, or mechatronics, this kit accelerates projects on wireless gesture control, prosthetic hand research, or assistive communication. Smart India Hackathon teams building sign-language translators or remote manipulators will find the hardware ready to integrate. It also serves ATL Tinkering Lab mentors running advanced workshops on embedded motion capture, and hobbyists who already solder and want a shortcut to a working haptic telepresence prototype.
