Deadspottr, a robot capable of monitoring wifi signal strength was built using ROS and Python, on the TurtleBot3 Platform. The build process, functionality, and final analyses are documented. Included is a ROS node that constantly publishes the wifi-signal strength as measured by dBm (decibels per milliwatt). Also included is the accompanying TurtleBot3 build documentation.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
