Cable Car Trolley Variant 2
Arduino Stepper Cable Car Trolley Kit for Zip Line Automation
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 build a trolley that rides a suspended wire and stops with pinpoint accuracy at encoded markers—the core mechanism behind automated zip lines, warehouse delivery rails, and camera sliders. Whether you're prototyping for Smart India Hackathon or building a physics model for a CBSE exhibition, you’ll assemble a real-world motion system that responds to sensors and code.
What You'll Build
A stepper-driven cable car trolley that glides along a wire (not included) and halts at user-defined positions using an LM393 optical encoder. A crisp 0.96-inch OLED shows live position data and target stops, while two tactile buttons let you cycle through stops. The result is a repeatable, programmable transport system you can adapt for light payloads or demonstration robots.
What You'll Learn
- Configuring a NEMA 17 stepper motor with an A4988 driver for smooth, precise motion
- Interfacing an LM393 optical encoder to read encoded strip patterns and trigger stop events
- Programming an Arduino Uno to count steps, map positions, and drive the motor accordingly
- Reading button inputs and updating an OLED display to create a user-controlled navigation interface

Who This Kit Is For
Ideal for CBSE Class 11–12 students building physics or computer science projects, B.Tech first-years from ECE/EEE/Mechanical branches prototyping mechatronics ideas, and Smart India Hackathon participants automating transport or logistics models. ATL Tinkering Labs can use it to demonstrate encoded motion, while hobbyists at IIT/NIT/VIT/BITS will find it a solid base for advanced zip line or camera slider applications.
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 instantly chat with your kit's AI companion for troubleshooting. You can also reach us on WhatsApp—our team typically replies within 24 hours.
Can this trolley carry a small load or camera?
Yes, the NEMA 17 stepper provides enough torque to move light payloads like a GoPro or a small sensor module along a horizontal or gently inclined wire. Make sure the wire tension and trolley grip suit your load.
Does the kit include the wire and pulleys?
No, the wire, mounting hardware, and pulleys are not included so you can customise the length, material, and tension for your specific installation—whether a short classroom demo or a long zip line prototype.
How do I program the target positions?
Use the two tactile buttons to cycle through pre-set stops (up to 5 by default). The Arduino code counts encoder strips and drives the stepper to the selected position; you can easily modify the code to add more stops or change stop logic.
Stepper driven trolley rides a wire and stops at encoded positions. Useful for zip line automation projects.
