Sport Form Coach Advanced Kit with ESP32 + MPU6050
Sport Form Coach Advanced Kit: Wearable Shoulder Elevation Assistant with ESP32 and MPU6050 IMU Feedback
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Repetitive overhead movements — in sports like cricket bowling, tennis serves, or volleyball spikes — demand precise shoulder mechanics. This kit lets you build a wearable assistant that senses your arm angle and applies servo-driven resistance or support to improve form and reduce strain. Two MG996R servos, guided by dual MPU6050 inertial measurement units and force-sensitive resistors, create an active shoulder-elevation coach that reacts to your motion in real time.
What You'll Build
You’ll assemble a lightweight, adjustable shoulder brace that uses real-time IMU data from your upper arm and torso to detect elevation angle. When you initiate an overhead motion, the pair of MG996R servos provide gentle, programmable torque to assist or correct your movement, while FSR sensors under the straps track muscle engagement. The result is a personal biomechanics coach that helps maintain proper form during repetitive overhead training.
What You'll Learn
- Calibrating dual MPU6050 IMUs for relative angle measurement between arm and torso.
- Controlling high-torque MG996R servos via PCA9685 PWM driver over I2C from an ESP32.
- Reading force-sensitive resistors for muscle activation feedback and integrating with motion control loops.
- Designing a battery-powered wearable system with voltage regulation using the LM2596 buck converter and LiPo power management.

How do I calibrate the dual MPU6050 sensors to accurately track shoulder angle?
The AI build guide includes a calibration routine that aligns sensor axes and computes relative orientation using a Madgwick filter. We provide starter code to run the calibration process step by step.
Can the servo torque be adjusted for different sports or user strength?
Yes, the PWM limits are configurable in the ESP32 firmware. You can set assist levels and responsiveness through a simple config file, and the AI companion explains how to modify parameters safely without overloading the servos.
Does the 3D printed frame fit all arm sizes?
The frame is parameterized; you receive a 3D printed version sized for an average upper arm circumference (28-34 cm). The build guide shows how to adjust the model in Fusion 360 and reprint if needed, or you can use the included Velcro straps for fine adjustment.
