ESP32-Powered Shoulder Assist Exoskeleton Kit
Build a Shoulder-Assist Wearable Exoskeleton - Earthquake Vibration Logger Plus Kit with ESP32 + MPU6050
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
The Earthquake Vibration Logger Plus Kit lets you construct a wearable assistive device that reduces shoulder strain during repetitive overhead tasks. Two MG996R high-torque servos work with dual MPU6050 inertial measurement units to sense arm posture and provide lifting assistance exactly when needed. Originally designed as a seismology data logger, this kit's motion-control core is equally suited for biomechanics and assistive robotics projects.
What You'll Build
You assemble a custom 3D-printed shoulder frame that straps onto the upper arm and torso. As you raise your arm, one IMU detects shoulder flexion while the second tracks upper-arm orientation. The ESP32 processes this data in real time and activates MG996R servos via a PCA9685 driver, delivering motorized lift that offsets muscle effort. Force-sensitive resistors (FSR 402) serve as user-trigger switches, keeping control intuitive.
What You'll Learn
- Dual-MPU6050 sensor fusion for tilt and acceleration angle estimation
- Servo control with PCA9685 I2C driver and torque modulation
- Integrating FSR 402 force sensors as analog input triggers
- Power management: stepping down 7.4V LiPo to stable 5V/3.3V rails
- PCB prototyping, soldering, and wearable electronics packaging

Who This Kit Is For
Ideal for engineering students tackling assistive robotics in Smart India Hackathon or major B.Tech ECE/EEE projects, particularly at IITs, NITs, VIT, or BITS Pilani. ATL Tinkering Lab mentors working with senior students on mechatronics and biomedical applications will find this a comprehensive, ready-to-assemble platform that bridges theory and practice.
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?
Your kit's AI companion provides real-time debugging, wiring checks, and code snippets. WhatsApp support is also available for direct guidance.
Can this kit also log earthquake vibrations?
Yes. The dual MPU6050 accelerometers and ESP32 data-logging capabilities are identical to a basic seismometer. The included firmware can be configured to record seismic activity to an SD card (not included) instead of controlling servos.
Is soldering necessary, and is it difficult for a beginner?
Yes, this is an advanced kit that requires soldering headers, PCB connections, and the buck converter. The AI guide includes soldering tips and pin-by-pin instructions, but prior basic soldering experience is assumed.
What prior knowledge should I have before starting?
Familiarity with Arduino IDE, I2C communication, and basic servo control is recommended. The kit's learning resources walk you through the project step by step, but comfort with C/C++ is a plus.
