Fully Autonomous Indoor Mapping Robot
Build a Fully Autonomous Indoor Mapping Robot with ROS, Lidar & Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your Raspberry Pi into the brain of a robot that scans rooms and builds live occupancy grid maps — while an Arduino Mega handles precision motor control. This kit walks you through creating a differential‑drive robot that sees its environment, localises itself, and navigates autonomously. Every sensor, driver, and power component arrives pre‑checked to work as a system, so you focus on the integration, not debugging mismatched parts.
What You'll Build
You’ll assemble a mobile robot equipped with an RPLidar A1 laser scanner and MPU6050 IMU. Running ROS on your Raspberry Pi, it uses the lidar to generate a real‑time 2D occupancy grid map, fusing odometry from wheel encoders and IMU data for robust localisation. The Arduino Mega runs a closed‑loop PID controller on each drive wheel, ensuring the robot follows precise trajectories even on uneven floors. By the end, the robot can autonomously explore a room, avoid obstacles, and save the map for future navigation.
What You'll Learn
- Set up ROS on Raspberry Pi and integrate RPLidar for real‑time SLAM
- Implement PID speed control on Arduino Mega using LM393 encoder feedback
- Fuse IMU data (MPU6050) with wheel odometry for drift‑resistant localisation
- Design a robust power distribution system with buck converters and a 12V SLA battery

Who This Kit Is For
Designed for engineering students and advanced makers confident with Linux and basic C++/Python. It’s ideal for B.Tech ECE/EEE final‑year projects on SLAM and autonomous navigation, Smart India Hackathon participants needing a reliable hardware platform, and robotics clubs at IITs, NITs, VIT, or BITS Pilani. If you’re ready to move beyond line‑following and build a real mapping robot, this kit matches your ambition.
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 for instant access to the AI build companion trained on this kit, or message us on WhatsApp for engineering support from our Bengaluru team.
Does the kit include a Raspberry Pi?
No — you’ll supply a Raspberry Pi 4 (or 3B+) with an SD card running Ubuntu 20.04 and ROS Noetic. All other hardware, from LIDAR to motor driver, is included and pre‑validated.
Can I modify the robot for outdoor navigation?
While optimised for indoor mapping, the hardware (RPLidar, IMU, encoders) can be extended for outdoor use with additional sensor fusion and path‑planning. The AI companion offers guidance on outdoor adaptations.
Is soldering required?
Yes — you’ll solder power distribution wires, encoder connectors, and prototype board routing. The kit includes a soldering iron, solder wire, and detailed schematics with step‑by‑step assembly images.
RPLidar + ROS on Raspberry Pi builds occupancy grid map. Arduino Mega handles motor PID.
