The main risk at this point is that we have not yet tested and integrated our systems, but we are hoping to have a full system initially working for our live demo in a bit over a week in order to demonstrate a mostly functional initial version of the project. To manage this risk we plan to start testing and integrating our systems as soon as possible (over the weekend and early next week) so that we have time to deal with unexpected issues before our initial project demo.
Since last week, there have been several minor design modifications in terms of the hardware and software that we will be using. We ordered an additional part for interfacing between the Raspberry Pi and the thermal camera, and a few more parts for setting up the physical robot. For software, we changed the SLAM and local path planning software that we will be using since our previously selected software was not compatible with current, maintained versions of ROS. We will now be using SLAM Toolbox instead of Hector SLAM, and Nav2 instead of TEB for local path planning.
