Mobile robots can readily map static environments for world building and navigation. But what if the environment is constantly changing? For researchers interested in understanding phenomena that change in both space and time, observations are vital. Current measurements techniques may require the deployment of vast arrays of sensors and manual observation campaigns by personnel, which are both slow and costly. If mobile robots can collect and synthesize data from ever-changing environments, such campaigns could be cheaper, faster, and more responsive.


Through the Ingenuity Labs Research Institute at Queen’s University, we have access to a Maritime Robotics Otter USV (uncrewed surface vessel).
