Stair Climber Robot Kit: 6-Wheel Rocker-Bogie + Arduino Uno + Ultrasonic
Stair Climber Robot Kit: Build a 6-Wheel Rocker-Bogie Robot with Arduino Uno & Ultrasonic Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This robot uses a 6-wheel rocker-bogie suspension system-the same principle behind Mars rovers-to climb steps up to 5 cm high. Each wheel is independently driven by a TT gear motor, giving you precise control over torque distribution and traction. Program its obstacle avoidance with the ultrasonic sensor and watch it navigate uneven terrain autonomously.
What You'll Build
You'll assemble a 6-wheeled platform that autonomously climbs small stairs and navigates obstacles using an HC-SR04 ultrasonic sensor. The rocker-bogie linkage allows every wheel to maintain ground contact, maximizing stability and pushing your mechanical design skills further. By the end, you'll have a fully functional robot ready for school science exhibitions, engineering competitions, or a Smart India Hackathon prototype.
What You'll Learn
- How rocker-bogie suspension distributes weight and improves step-climbing capability
- Independent motor control with dual L298N drivers and Arduino PWM signals
- Torque calculation and gear motor selection for stable payload handling
- Integrating an ultrasonic sensor for real-time obstacle avoidance and autonomous navigation

Who This Kit Is For
This kit is built for Class 11-12 CBSE students diving into advanced robotics, B.Tech ECE/EEE undergraduates, and teams preparing for Smart India Hackathon or institution-level tech fests at IIT, NIT, VIT, or BITS. If you've already mastered a basic line-follower and want to explore mechanical design and torque, this is your natural next step.
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 that understands every connection and code line in this kit. If you need a human touch, drop a message on our WhatsApp support-we'll reply within hours.
Does this robot really climb stairs?
Yes, the rocker-bogie linkage lets each wheel pivot independently, so the robot walks up steps up to 5 cm high when the motors are driven correctly. The kit includes pre-cut acrylic plates and hardware to assemble the exact linkage you need.
Can I program it for fully autonomous navigation?
Absolutely. The included HC-SR04 ultrasonic sensor feeds distance data to the Arduino Uno, allowing you to write obstacle-avoidance routines and map-free navigation code. Sample sketches are available through the AI companion.
What prior knowledge do I need?
You should be comfortable with basic Arduino programming (if-else, analogWrite) and have assembled a simple circuit before. The build guide walks you through the mechanical linkage step-by-step, so no prior mechanical design experience is required.
6-wheel rocker-bogie mechanism with individual motor control climbs small steps. Teaches mechanical linkage and torque.
