In this tutorial, I’ll walk you through building a four-transmission robot using the BLIX Robotix DIY Educational Kit. This project is perfect for beginners and young tinkerers who want to explore mechanical motion, simple gear mechanisms, and basic engineering using an easy-to-use construction kit.
📦 What Is the BLIX Kit?
The BLIX Robotix Educational Building Kit is a hands-on STEM kit designed to help students and enthusiasts build mechanical bots and structures using interlocking plastic parts, gear systems, and basic motion principles. It comes with a user manual that includes multiple robot models you can build step-by-step.
I followed the guide included in the manual to make a 4-transmission robot that demonstrates how mechanical power can be distributed and controlled across multiple wheels.
🧰 Components Used:
Blix Robotix Kit (used this one — Click here)
Plastic wheels and connectors
Gearbox and mechanical joints
Transmission shafts
Frame and chassis pieces

🛠️ How to Build the 4-Transmission Robot
Here’s a breakdown of how I made it using the manual:
Step 1: Unbox your BLIX kit and go through the instruction manual to identify the 4-transmission bot model.
→
Step 2: Start building the base frame using rectangular connectors and screws provided in the kit.
→
Step 3: Assemble the gearbox by connecting gears to the shaft system for each wheel. This allows for torque transfer.
→
Step 4: Attach the motors (if your version supports motorized builds) or use manual cranks to demonstrate motion.
Step 5: Fix all four wheels to the chassis and connect them to the central frame using transmission rods.
Step 6: Test each wheel by rotating one manually—observe how the other three move due to the connected transmissions.
Step 7: Secure all loose joints using the provided fasteners and do a final test to ensure smooth rotation.

🎯 What You’ll Learn:
Basics of mechanical transmission
Gear and shaft assembly
Structural stability in moving parts
Importance of symmetry in robotic design
This project is great for beginners, school projects, and anyone curious about STEM. It’s 100% non-electronic, so it’s safe and perfect for classroom learning too!
