Gesture Recognition Wand Kit with ESP32 + Sensor
AI Gesture Recognition Wand Kit: ESP32-S3, TFLite, and 4-DOF Servo Arm
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 pointing, clenching, or swiping your hand to command a robotic arm without a single button. This kit turns that vision into reality. You’ll mount APDS9960 and MPU6050 sensors on a velcro glove, fuse their data, and run a TensorFlow Lite model on an ESP32-S3 to classify six distinct gestures in real time, then actuate four MG90S servo motors via a PCA9685 driver.
What You'll Build
A fully functional gesture-controlled robotic arm that mirrors your hand movements instantly. All computation happens on the edge — no cloud, no latency. The 4-DOF arm demonstrates how sensor fusion and on-device AI can replace traditional controllers in a wearable, responsive system.
What You'll Learn
- Fusing APDS9960 (proximity, colour, gesture) with MPU6050 (accelerometer/gyroscope) data into a robust feature set
- Training a TensorFlow Lite model for 6-class gesture classification and quantising it for ESP32-S3
- Deploying and running inference at 15+ FPS on the ESP32-S3 using the ESP-IDF framework
- Controlling four servos through a PCA9685 I2C driver to achieve smooth 4-DOF arm motion

Who This Kit Is For
B.Tech ECE/EEE students working on final‑year projects in embedded machine learning, participants in Smart India Hackathon building assistive technology or automation prototypes, and ATL Tinkering Lab instructors looking for an advanced AI + robotics capstone. It’s also a natural fit for IIT/NIT/VIT/BITS engineers prototyping real‑time wearable interfaces.
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?
The AI companion walks you through each step, and if you need a human touch, our engineers are available on WhatsApp to unblock you.
Can I modify the kit to recognise more than 6 gestures?
Absolutely. The ESP32‑S3 has headroom for a larger model. The companion includes guidance on collecting additional training data and retraining your TensorFlow Lite model.
Does the kit include a pre‑trained model or do I train it myself?
We ship a working pre‑trained model so you can test the system immediately. But you’ll also work through the full training pipeline in Google Colab, so you truly own the AI logic.
Is coding experience required?
Yes — this is an advanced kit. You should be comfortable with C/C++ (ESP‑IDF) and Python (TensorFlow). Familiarity with embedded systems and basic ML concepts will help you get the most out of it.
Gesture — APDS9960 + MPU6050 glove detects 6 gestures. ESP32-S3 TFLite model classifies gesture and drives 4-DOF servo arm.
