CrabLine Robotics

Corporate marketmarineinspectionCurated record

Case Western Reserve University Crab Lab spinout building crab-inspired amphibious legged robots for underwater work: construction and decommissioning of subsea structures, biofouling removal, offshore-platform and pipeline maintenance, and UXO retrieval. Inspired by crabs' inward-pulling grasp, the platform stabilizes on a substrate and traces predefined tool paths, addressing tasks divers and conventional ROVs handle poorly in deep, cold, turbid water. Tethered variants can crawl to unexploded ordnance, grasp it, and be craned in. Backed by an NSF SBIR Phase I award; exhibited at CES. Note: overturns a prior prescreen reject that misclassified the company as a non-robotics listing — it is a verified robot vendor.
