Stewart Platform Hexapod Variant 7
Master Inverse Kinematics with the Stewart Platform Hexapod Variant 7 Kit for Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a precision 6-degrees-of-freedom motion platform that tilts, rolls, pitches, and heaves on demand. This kit brings the complex mathematics of parallel manipulators to life — you’ll implement inverse kinematics to control six MG90S servos and receive real-time orientation feedback from an MPU6050. Whether simulating flight dynamics or stabilizing a camera payload, you’ll gain hands-on experience with the control theory that drives industrial simulators and robotic arms.
What You'll Build
A fully functional Stewart platform capable of moving in 6DOF under closed-loop control. The platform uses an Arduino Mega and PCA9685 driver to synchronize six servos via ball linkages, responding instantly to tilt or acceleration data from the MPU6050. Once calibrated, you can program it for wave-like motions, pre-defined trajectories, or responsive stabilization — a complete parallel kinematics system.
What You'll Learn
- Derivation and coding of inverse kinematics for a 6-6 parallel manipulator
- PID control implementation using MPU6050 gyroscope feedback to maintain orientation
- Servo calibration, pulse-width modulation, and multi-axis synchronization via PCA9685
- Prototyping on PCB boards, soldering robust connections, and integrating power decoupling

Who This Kit Is For
Ideal for B.Tech ECE/EEE students integrating inverse kinematics into their coursework, Smart India Hackathon teams developing motion simulators, and hobbyists prototyping closed-loop robotics. It challenges learners at IIT, NIT, VIT, and BITS project labs, and can be adapted for ATL Tinkering Labs with mentor support, bridging theory and real-time servo control.
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?
Open the AI companion through the QR code to get step-by-step debugging for inverse kinematics errors, or send us a photo on WhatsApp for direct troubleshooting.
Does this kit require advanced soldering skills?
You'll need to solder header pins and capacitors onto three PCB boards, but the AI guide includes clear close-up shots and a temperature guide to get clean joints; it's a great skill to acquire.
Can I control the platform from a PC or ROS?
Yes, the Arduino Mega communicates via serial over USB. Example code shows how to send target positions from a Python script, and you can extend it to ROS nodes for more complex automation.
Is the platform strong enough to hold a camera or small payload?
The MG90S servos can handle a well-balanced payload up to 200g. For heavier setups, the same inverse kinematics logic scales to larger servos — you can upgrade easily without reworking the code.
Six SG90 servos form a parallel Stewart platform. Inverse kinematics computes joint angles for 6DOF motion.
