A low-cost autonomous rover for polar science
We present the developmental considerations, design, and deployment of an autonomous modular terrestrial rover for ice-sheet exploration that is inexpensive, easy to construct, and allows for instrumentation customization. The total construction cost for this rover is less than USD 3000, approximate...

Operation of the rover in hazardous areas circumvents the substantial expense and risk to personnel associated with conventional, crewed deployments.
