Blind Stick Obstacle Detector Kit v6
Blind Stick Obstacle Detector Kit v6 – Faster Room Mapping Through Parallel Robotics
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Most assistive navigation aids rely on a single sensor, scanning one direction at a time. This kit flips that idea: three compact robots, each a Raspberry Pi Zero 2W on a motorised chassis, simultaneously map different sections of a room using ultrasonic sensors and a shared RPLidar. Their partial maps are then fused on a central Raspberry Pi 5 to create a unified obstacle layout—delivering complete spatial awareness far faster than a single robot ever could.
What You'll Build
You’ll assemble and program three independent mapping robots and a central coordinator. The Pi Zero 2W nodes navigate distinct areas, transmitting time-stamped sensor data via WiFi. The Pi 5 aggregator runs a custom sensor-fusion stack to merge the maps in near real time. The final output is a live, annotated floor plan that can be relayed to a haptic or audio feedback system—the foundation of a real-world blind stick obstacle detector.
What You'll Learn
- Multi-robot SLAM principles: distributing scan tasks, time synchronization, and map merging
- Sensor integration on resource-constrained hardware: HC-SR04 ultrasonic arrays and RPLidar over UART
- Motor control and odometry using Cytron drivers and DC motors on Pi Zero 2W
- Centralized data aggregation and fusion on a Raspberry Pi 5 with optional NVMe storage for logged runs

Who This Kit Is For
This intermediate kit is ideal for B.Tech ECE/EEE students developing assistive tech prototypes for Smart India Hackathon or final-year projects. It also suits CBSE Class 11–12 innovators at ATL Tinkering Labs who have moved beyond Arduino and want to tackle distributed embedded systems. Engineering researchers at IITs, NITs, or VIT exploring multi-agent mapping will find the hardware stack ready to deploy.
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?
Your AI companion walks you through every wiring diagram and configuration file; if you still need human help, our WhatsApp support responds within hours.
Does the kit include a pre-written mapping algorithm?
Yes, sample Python scripts for ROS2-based multi-robot SLAM are included on the microSD cards, with clear comments so you can modify them for your own sensor layout.
How do the three Pi Zero 2W robots communicate with the Pi 5?
They create a local WiFi network with a router you supply; the companion guide offers two topologies (ad-hoc or access-point mode) depending on your test area size.
Can this setup be converted into a portable blind stick?
Absolutely. Once you validate the aggregated maps, you can strip down one robot’s chassis and integrate the sensors with a haptic feedback module—the learning covers that transition.
Accessibility — 3 Pi Zero 2W robots each build partial maps that are merged on Pi 5 aggregator — faster coverage than single robot SLAM.
