Marenus — Amphibious Crawling Robot
A rugged and highly adaptable platform engineered for shoreline, intertidal, and breakwater operations. Its modular layout supports interchangeable payloads for CPT, cable tracking, mine disposal, sonar inspections and precise manipulation tasks. Powered by a high-bandwidth tethered Ethernet link, Marenus enables real-time control and data acquisition even in demanding near-shore environments.
