C2-I robotic crawlers operate in the active surf zone, the contaminated estuary, and the mine-threatened shoreline. These are the environments that exceeded the operational envelope of every conventional platform sent before them. Man-in-the-loop or fully autonomous. Designed to keep soldiers out of the most hazardous terrain on the battlefield.
The Sea Otter and Sea Ox are marinized robotic crawlers developed and manufactured by C2-I Engineering in Shrewsbury, Massachusetts. Both platforms operate man-in-the-loop or fully autonomously across the full littoral spectrum, from open water through the surf zone to dry land, in a single mission profile. Both were built for programs where the operational requirement could not be met by any existing platform. Not adapted. Designed from requirement.
A marinized robotic crawler for sustained operations across the full littoral spectrum: shallow coastal water, estuarine terrain, riverine crossings, and dry land in a single mission profile without reconfiguration. Capable of autonomous mapping, environmental monitoring, water sampling, and UXO neutralization. Delivered to and operated by the U.S. Army Corps of Engineers and Scripps Institution of Oceanography.
The high-payload platform in the C2-I lineup. Built for environments that defeat lighter systems: heavy surf, strong river currents, and mine-threatened shorelines. Operated by the U.S. Marine Corps in direct support of subsurface mine warfare operations. Open-deck architecture accepts customer-owned sensors and mission payloads without hull modification. The Marine Corps chose this platform because nothing else could meet the requirement.
There is no commercial product adapted underneath the Sea Otter or Sea Ox. Both platforms were engineered ground-up for the conditions they operate in, built in-house, and delivered to programs where no catalog item could fill the requirement. C2-I has developed these systems through competitive SBIR and STTR funding and delivered them directly to defense and federal customers. Every program begins with the operational requirement. Nothing else determines the design.
C2-I Engineering is fewer than ten people. When a fielded system needs support, the program manager reaches the engineers who designed the hardware directly. No help desk. No support contractor. Our sustainment model covers technical support, operator training, and maintenance planning through the full operational life of the system. The team that built it is accountable for keeping it in the field.
Both platforms carry an open-deck architecture designed to accept third-party sensors and mission payloads without modifying the hull or drive system. C2-I has integrated acoustic sensors, water sampling equipment, RTK positioning systems, and multi-sensor packages for programs spanning UXO investigation, subsurface mine warfare support, and benthic ecosystem monitoring. If the sensor can survive the environment, we can integrate it.
C2-I Engineering starts from the operational requirement, not the product sheet. If the mission calls for hardware that does not yet exist, that is where we start. Reach the engineers directly.
