Multi-Robot Tools and Techniques for Exploration and Mobile Surveying

Whether working on Earth or beyond, access to accurate and timely geospatial information about one's operating environment is critical to matters of planning, productivity, and safety.  For example, mapping of the discontinuity planes in a rock mass is an important input to the process of designing appropriate ground support systems in mining, or for understanding geological processes on Mars.  Yet, most contemporary tools for geospatial surveying and mapping remain highly manual, utilize stationary platforms (e.g., are tripod-mounted), and thus depend significantly on physical presence of and input by human operators.  Most techniques also rely on data from only one source at a time and on the availability of satellite-based GPS information for geolocation, which is often not practical (e.g., in underground excavations).  The essence of this application is born from the realization that there exists a significant and unexplored opportunity in the combination of ideas from contemporary field robotics with the real problems of geospatial surveying and mapping in remote, harsh, uncertain, and unstructured environments where human presence is either not possible, hindered in some way, or highly undesirable (e.g., deep underground, far north, on other planets).
