Mapping environmental threats in GPS-inaccessible locations – such as underground installations, or the passageways of ships – can certainly pose some challenges. While there are robotic systems that can do the job, robots aren’t necessarily the best choice for cramped quarters or uneven terrain. That’s why a team of scientists at Johns Hopkins University have developed the backpack-mounted Enhanced Mapping and Positioning System ... or EMAPS.
