Exoskeleton Shoulder Assist Kit with ESP32 + MPU6050
Exoskeleton Shoulder Assist Kit with ESP32 + MPU6050 – Cut Overhead Fatigue with Motion‑Activated Servo Lift
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 reaching up to change a lightbulb, paint a ceiling, or stock a high shelf and feeling a gentle mechanical assist that takes the strain off your shoulder. This kit delivers that reality. You build a wearable exoskeleton that pairs two MPU6050 inertial sensors with a pair of high‑torque MG996R servos; the moment your arm rises toward an overhead position, the servos pull calibrated cables to support your humerus, cutting the perceived load dramatically. Force‑sensitive resistors in the grip zone ensure the assist only engages when you are actually holding a tool, and an OLED screen gives real‑time angle and battery feedback.
What You'll Build
By the end of the build you will have a fully wearable, self‑contained shoulder assist unit. The 3D‑printed frame houses everything: two MG996R servos drive bowden‑style cables that run along your shoulder and bicep, while the PCA9685 servo driver and ESP32 run a fusion algorithm that interprets IMU data to decide when and how much torque to apply. The FSR 402 sensors under your fingers turn the assist on only during active tool use, preventing unintended movement. The OLED display cycles between angle readouts, assist level, and battery status. Velcro straps let you don and doff the device in seconds.
What You'll Learn
- Sensor fusion with complementary filters to compute arm pitch angles from two MPU6050 IMU streams
- High‑torque servo programming via PCA9685 over I2C, including stall detection and load‑adaptive PWM mapping
- Graphical OLED dashboards using U8g2 to visualize real‑time IMU data, battery voltage, and assist triggers
- Power budget management: stepping down a 7.4 V LiPo to 6 V for servos and 3.3 V for the ESP32 without brownouts

Who This Kit Is For
This advanced kit matches B.Tech ECE/EEE capstone projects at institutions like IIT Madras, NIT Trichy, and VIT, where students need a working wearable prototype for rehabilitation or industrial assist. Smart India Hackathon hardware track teams will find the IMU-servo loop ready to hack on day one, while professionals building ergonomic interventions for manufacturing lines can skip sourcing and go straight to testing on their shop floor.
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 on the box to launch the AI companion or message us on WhatsApp. It knows every wire and line of code in this specific exoskeleton project.
Can I modify the trigger threshold for the servos?
Yes, the firmware is open and well-commented. You can change the pitch angle trip point and the assist force curve in the code.
Is the 3D printed frame one-size-fits-all?
The frame is designed to fit most adult male arm circumferences; the adjustable Velcro straps and flexible PLA sections allow fine-tuning for a snug, comfortable fit.
How long does the battery last on a full charge?
With a 2000 mAh LiPo, expect about 4-5 hours of typical intermittent overhead assist use, depending on servo loading and OLED brightness.
Two MG996R servos and IMU feedback assist shoulder elevation for fatigue reduction during repetitive overhead work.
