Remote control: Not possible. Driven only from the Sarcos tablet/handheld operator control unit.
Overview
A tough, hand-carried snake-like tracked robot for industrial inspection, bomb squads and search and rescue that could climb stairs, slide up steel doors on magnetic tracks and crawl into pipes. It was one of the few snake robots sold commercially. Sarcos pivoted to AI software in 2023 and renamed itself Palladyne AI in 2024, so the Guardian S is no longer offered.
