Hazardous Gas Detection using Nanosaur with VSLAM

A ROS2 robot that maps its environment with VSLAM while detecting hazardous gases.

Advisor: Prof. Siddharth Tallur, IIT Bombay  ·  Jan 2023 – Apr 2023  ·  Best Project Award

An add-on sensing and mapping system for the Nanosaur robot built on an NVIDIA Jetson Nano.

  • Designed an add-on circuit to detect NH₃, CO₂, CO, CH₄, and other gases.
  • Implemented ORB-SLAM2 VSLAM with a stereo camera and integrated it into the robot using ROS2.
  • Enabled remote Wi-Fi control and a server-based dashboard showing gas levels and a 3D map of the environment.
