Zip Line Trolley Robot with Arduino Uno & Stepper Motor Kit
Build a Zip Line Trolley Robot with Arduino Uno & Stepper Motor
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 kit lets you assemble a motorized trolley that rides along a taught wire or zip line, stopping precisely at encoded positions. Imagine automating a model cable car, a warehouse delivery system, or a science fair exhibit that demonstrates closed-loop motion control. You'll program an Arduino Uno to read an LM393 encoder and drive a NEMA 17 stepper for accurate positioning, turning abstract concepts into a working machine.
What You'll Build
A functional wire-riding trolley with a 0.96-inch OLED display showing current position and target distance. The system uses an LM393 encoder disk attached to the wheel to track movement, while the A4988 driver precisely controls the stepper motor. Tactile buttons let you set target positions on the fly, making it perfect for interactive demonstrations and zip line automation prototypes.
What You'll Learn
- Interface a NEMA 17 stepper motor with an A4988 driver and Arduino Uno
- Read rotary encoder pulses for closed-loop position feedback and error correction
- Display real-time travel data-speed, position, and target-on an OLED screen
- Design interrupt-driven button controls for responsive user input without delay loops

Who This Kit Is For
CBSE Class 11-12 students building a physics or computer science project on motion control, B.Tech ECE/EEE students preparing a mini project on embedded systems, and participants in Smart India Hackathon hardware challenges. ATL Tinkering Labs and robotics clubs will find it an ideal intermediate project that bridges theory and hands-on zip line automation.
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 to chat with the AI companion, which has step-by-step guidance and debug tips for this exact kit. You can also reach us on WhatsApp for direct help.
Can the trolley climb a steep zip line?
The kit is designed for low-angle slopes and level wires. Steep inclines may require a higher torque motor or counterweight; you can extend the design using the same code logic.
Is this suitable for a Smart India Hackathon project?
Yes, it's an excellent base for smart logistics or automation solutions. Add wireless control or multiple encoded stops to create a unique hardware prototype for the competition.
Do I need a soldering iron?
No soldering is required. All connections use the included breadboard and jumper wires, making it safe and reusable for classroom and lab settings.
Stepper driven trolley rides a wire and stops at encoded positions. Useful for zip line automation projects.
