Pi 4 SLAM Navigation Robot
Pi 4 SLAM Navigation Robot Kit — Build a Self-Navigating Robot Using RPLidar & ROS
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Engineer a robot that scans rooms, builds live 2D maps, and navigates autonomously — no GPS needed. The Pi 4 SLAM Navigation Kit pairs an RPLidar A1 laser scanner with a Raspberry Pi 4 running Hector SLAM to generate real-time occupancy grids. An Arduino Nano controls the motors through rosserial, creating a full ROS stack you can extend for warehouse bots, delivery robots, or campus navigation projects.
What You'll Build
You'll assemble a differential-drive robot that uses laser scan data to perform simultaneous localization and mapping. The robot streams a dynamic 2D map to your laptop over Wi-Fi while intelligently avoiding obstacles. By the end, you'll have a fully autonomous platform ready for path planning, multi-robot swarms, or integrating additional sensors like cameras.
What You'll Learn
- Integrate RPLidar A1 with Raspberry Pi 4 via USB and configure the ROS driver
- Implement Hector SLAM to build 2D occupancy grids without wheel odometry
- Use rosserial to bridge Arduino Nano motor commands with ROS topics
- Calibrate encoder feedback for closed-loop velocity control on a differential drive

Who This Kit Is For
B.Tech students in ECE, EEE, or Mechanical Engineering tackling autonomous systems projects will find a ready ROS stack. Smart India Hackathon teams needing rapid SLAM deployment, and robotics enthusiasts preparing for e-Yantra or Techfest competitions, can skip the sourcing chaos. It’s also ideal for ATL mentors introducing advanced robotics to undergraduates.
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?
Our AI companion walks you through every step, and you can message us on WhatsApp for real‑time help from our engineers.
Do I need prior ROS experience?
This kit assumes basic Linux and Python comfort, but the AI companion and provided ROS nodes can be followed even if you’re new to ROS.
Can I use a different motor driver or battery?
The kit is pre-tested with the supplied L298N and 12V 3Ah battery; swapping components may break the rosserial PID loops and SLAM performance.
Will this robot work with ROS 2?
The kit ships with ROS Noetic for Pi 4. ROS 2 support is not pre-configured, but the AI companion can guide you through porting the stack.
RPLidar A1 on Pi 4 builds 2D occupancy grid using Hector SLAM. Motor driver on Arduino via rosserial.
