Amphibious Robot for Soil and Water Testing

CST AR1 Robot


AR1 is an amphibious robotic vehicle that excels where other vehicles can't go. An electric drive powers it over mud, water, sand and firm ground to take samples and measurements from otherwise inaccessible locations.

AR1 is specifically built for the inhospitable environment of tailings ponds, giving operators immediate feedback on the state and composition of deposits to speed up reclamation. With a wide range of payload capabilities, AR1 is well suited to researchers, environmental scientists, hydrologists, geotechnical engineers, and others needing samples and measurements from muddy, swampy, difficult to access areas.
