Hexapod 18-Servo Walker Kit with Arduino Mega + Servo
Arduino Mega 18-Servo Hexapod Walker Kit with Tripod Gait & IMU Terrain Adaptation
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 a six-legged robot that walks with a stable tripod gait and adjusts its stride automatically when it steps onto an uneven surface. This hexapod walker uses 18 independent MG90S servos, an Arduino Mega, and real-time IMU feedback to maintain balance on slopes. It is a complete platform for exploring inverse kinematics, multi-servo control, and sensor-driven motion—ideal for an ambitious engineering project or robotics competition.
What You'll Build
You will assemble and program a fully functional hexapod that walks forward, backward, and turns using a dynamic tripod gait. The MPU6050 IMU continuously monitors tilt and feeds orientation data to the PCA9685 servo drivers, enabling the legs to adapt step height and stride length when terrain changes. The transparent acrylic body shows off the wiring and 18 synchronized servos moving in unison, making it a demonstration piece as much as a research tool.
What You'll Learn
- Wiring and controlling 18 servo motors using dual PCA9685 drivers from an Arduino Mega
- Coding a tripod gait algorithm with configurable stride and height parameters
- Fusing MPU6050 accelerometer and gyroscope data for real-time terrain adaptation
- Managing high-current power distribution with a LiPo battery and LM2596 buck converter
- Soldering through-hole and SMD components on three prototype PCBs, and assembling a durable acrylic chassis with 60 M2 bolts

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part — servo torque, driver logic levels, battery voltage drop | Pre-tested as a system, all 18 servos matched and drivers already configured for Mega I2C |
| Build support | Forums and scattered tutorials, often for different hexapod designs or older hardware | AI companion trained on this exact project with step-by-step guidance, plus WhatsApp backup |
| Time to first working build | Days of debugging servo chatter, gait sync, and power resets | Hours, with tested code and clear assembly instructions that prevent common pitfalls |
| Shipping coordination | Multiple sellers, multiple delays, risk of missing or wrong parts | One shipment from Bengaluru in 3-5 days, with every bolt and cap included |
Who This Kit Is For
If you are a B.Tech ECE or mechatronics student preparing for Smart India Hackathon, this kit gives you a ready robotic platform to build upon. CBSE Class 12 students with ATL Tinkering Lab experience can advance to complex motion control for their final projects. Makerspaces at VIT, NIT, or IIT campuses will find it a comprehensive workshop-in-a-box for teaching servo-based walking robots.
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 access the AI companion trained on this exact hexapod project; you can also reach our support team via WhatsApp for human help during Indian business hours.
Do I need prior soldering and Arduino experience?
Yes, this is an advanced kit. You should be comfortable soldering small components like 100nF capacitors and programming Arduino in C++. The schematics and code are provided, but familiarity with servo control, I2C, and power management is assumed.
How does the hexapod achieve terrain adaptation?
The MPU6050 IMU measures pitch and roll. The Arduino Mega’s gait algorithm reads these angles and dynamically adjusts leg lift height and stride length for each of the six legs, maintaining stability on slopes up to approximately 15 degrees without toppling.
Can I use a different microcontroller like ESP32?
The kit is designed for Arduino Mega due to its 5V logic and ample GPIO. The AI companion and example code are optimized for the Mega’s I2C and servo libraries. You could adapt it for ESP32, but you would need to rewrite the driver layer; we recommend starting with the included Mega for a known-working build.
