We got hacked on 3/27/2021 – most likely due to improper ssh configuration and usage. As a result, we had to wipe the Xavier, set up our environment, and reinstall all our dependencies which took a significant amount of time.
Current Risks and Mitigation
Because of the lack of on-campus wifi connectivity, we’ve decided to move the Roscore to run on-board the robot so it can run autonomously even when the ground station gets temporarily disconnected.
Worst case, we can narrow down our delivery area to a selected subset of campus roads that are flat and have consistent wifi connectivity.
