Blind Stick Obstacle Detector Kit with Arduino Nano + NRF24
Advanced Leader-Follower Obstacle Avoidance Robot Kit with Arduino Nano & NRF24
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine two tiny autonomous vehicles working in perfect sync — the leader scans for obstacles and decides the path, while the follower tracks its every move without a single wire connecting them. This kit brings that accessibility-inspired concept to your workbench, giving you hands-on experience with wireless coordination algorithms that could one day guide a visually impaired person through a busy street.
What You'll Build
You'll assemble two 2WD robot chassis, each powered by an Arduino Nano, and link them via NRF24L01 transceivers. The leader robot uses an ultrasonic sensor to detect obstacles and autonomously navigate, while the follower robot constantly receives the leader’s coordinates and replicates its path in real time — a true leader-follower system. The result is a portable demo that showcases distributed robotics and low-latency wireless control.
What You'll Learn
- Implementing PID or simple proportional control for motor synchronization between two independent robots
- Configuring NRF24L01 modules for reliable wireless data transfer and packet handling
- Using ultrasonic sensors for real-time obstacle detection and path correction
- Designing a leader-follower algorithm that maintains spatial coordination without physical tether

Who This Kit Is For
Ideal for B.Tech ECE/EEE students tackling final-year projects, Smart India Hackathon teams prototyping assistive solutions, and ATL Tinkering Lab mentors guiding advanced robotics modules. If you're comfortable with Arduino programming and ready to dive into wireless protocols, this kit delivers a publication-worthy demonstration of distributed intelligence.
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 build companion, which has seen every step and common error in this exact project. You can also send a WhatsApp message to our support team for a human response within hours.
Can this kit be used for a college final year project?
Absolutely. Many students have used similar Compoden kits to demonstrate advanced concepts like multi-agent coordination and wireless sensor networks. The AI companion can help you refine your documentation and algorithm explanation.
Do I need prior experience with NRF24L01 modules?
Not necessarily. The kit’s AI companion includes a step-by-step guide on wiring, library installation, and packet structure. Basic familiarity with Arduino IDE and C++ is helpful, but the wireless setup is fully explained.
What programming skills are required?
You should be comfortable uploading sketches to Arduino Nano and editing variables in code. The AI companion walks you through the entire leader-follower logic, so even if you’ve never written a coordination algorithm before, you’ll complete it successfully.
Accessibility — Two small NRF24 linked robots coordinate using a leader-follower algorithm. Leader avoids obstacles, follower tracks leader.
