Self-Balancing Inverted Pendulum Robot
Self-Balancing Inverted Pendulum Robot – Arduino PID Capstone Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You will build a two-wheeled self-balancing robot that stands upright using a real-time PID loop — the same challenge faced in Segway-style transporters and modern bipedal robots. This project is designed as a capstone-level control systems hands-on exercise, demonstrating sensor fusion, motor driver control, and feedback loop tuning.
What You'll Build
A self-stabilizing differential drive robot that maintains vertical balance by continuously adjusting motor speeds based on MPU6050 accelerometer-gyroscope data. Once built, you can extend it to remote control or autonomous navigation, making it a showcase-worthy addition to your final-year project portfolio.
What You'll Learn
- Implement a discrete-time PID controller on Arduino
- Fuse accelerometer and gyroscope data to estimate tilt angle with complementary filter
- Configure A4988 stepper drivers for microstepping and current limit
- Tune PID gains (Kp, Ki, Kd) for critical damping of an unstable system

Who This Kit Is For
This kit is ideal for B.Tech ECE/EEE/Mechanical final-year students at institutions like IITs, NITs, VIT, and BITS Pilani, executing a control systems capstone. It's also suited for Smart India Hackathon participants building self-balancing robots, and ATL Tinkering Lab mentors demonstrating advanced embedded control concepts. If you've completed basic Arduino and want to tackle a real engineered system, this is your kit.
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?
Our AI companion, trained on this exact robot, understands every step. If it can't resolve your issue, WhatsApp chat connects you directly to our support team within minutes.
Is the PID tuning process covered?
Yes, the AI companion walks you through initial Kp, Ki, Kd values and iterative tuning to achieve stable vertical balance, using your robot's real-time angle data.
Can I upgrade to higher-torque NEMA17 motors later?
The A4988 drivers and power setup are capable of handling up to 45Ncm NEMA17 motors. The companion will guide you on recalculating PID gains if you switch motors.
Do I need a soldering station or equipment beyond what’s in the kit?
A basic soldering iron and solder wire are included. You'll just need a multimeter and a laptop with Arduino IDE — both common in any engineering workshop.
NEMA17 steppers driven by A4988 with MPU6050 PID loop maintain vertical balance. Capstone control systems build.
