Self-Balancing Step Counter Robot Kit Arduino PID Online India
Build a Self-Balancing Fitness Step Counter Robot with Arduino PID Control and NEMA17 Steppers
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Move beyond textbook theory and construct a two-wheeled robot that uses an MPU6050 inertial measurement unit, a finely tuned PID loop, and NEMA17 stepper motors to maintain vertical balance while counting every rotary step as a fitness metric. This kit transforms control systems concepts into a tangible, self-correcting physical platform — ideal for a capstone project or final-year demonstration.
What You'll Build
You'll assemble and program a robot that fuses gyroscope and accelerometer data to estimate its tilt angle in real time. That angle feeds a PID controller running on an Arduino Uno, which sends corrective step pulses to two A4988 drivers, rotating the NEMA17 motors just enough to keep the acrylic frame upright. An onboard step-counting algorithm tracks motor pulses as “steps,” mimicking a pedometer for your robot — a practical blend of motion sensing, feedback loops, and embedded system design.
What You'll Learn
- Design and tune a complete PID control loop for real-time balance stabilization
- Fuse MPU6050 gyroscope and accelerometer readings using complementary filter algorithms
- Interface A4988 stepper drivers with Arduino and control bipolar NEMA17 motors precisely
- Develop a step-counting logic that translates motor rotations into a fitness step metric

Who This Kit Is For
Designed for B.Tech ECE and EEE final-year students tackling capstone control systems assignments, Smart India Hackathon teams needing a motion-sensing hardware demo, or ATL Tinkering Lab mentors guiding advanced robotics projects. If you are at IIT, NIT, VIT, or BITS Pilani and want a soldering-heavy, theory-to-practice journey through PID tuning and sensor fusion, this build delivers exactly that.
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 our WhatsApp support line connects you to an engineer familiar with this kit’s exact configuration.
Do I need prior experience with PID controllers?
Some familiarity with control theory helps, but the companion provides reference code snippets and tuning strategies that make the PID implementation approachable even if you are exploring it for the first time.
Is soldering required?
Yes, the PCB prototype board and sensor connections demand soldering; the included iron and solder wire ensure you have the tools immediately.
Can I use this kit as my major project?
Absolutely. The combination of real-time control, sensor fusion, and embedded programming aligns with typical capstone project requirements and gives you a working hardware demonstration.
Fitness — NEMA17 steppers driven by A4988 with MPU6050 PID loop maintain vertical balance. Capstone control systems build.
