A project log for Advanced Fire Search and Rescue Drone

A drone that will be able to navigate its way around inside of a building automatically, such as room mapping, but for the entire building.

Drone: Our Drone will be based off of DJI’s Zenmuse XT 2 drone. Some of the differences however, will be the fact that the drone will enter the house and won’t be as expensive and heavy.

Camera: We considered the following different cameras for our Drone:

All of these cameras look great, except that they need to be able to handle being in a fire. We will need to either make the cameras more rugged or get a camera that can handle the extreme conditions that it will be in.

Vision: We had two different options for how the camera will generate a 3d map for us. The first option is Stereoscopic vision. Stereoscopic vision is basically human binocular vision. The second method is Lidar. How Lidar works is that is uses light from a pulsed laser that can measure ranges. It does this will thousands of points that form a 3d map.

We ended up going with Lidar since it doesn’t need visual analysis.

What we will be doing next is looking more at Lidar and rugged Cameras.
