Botzan Robotics builds autonomous underwater robots that clean and inspect ship hulls at commercial ports.
Botzan Robotics (Chinese: 泊展机器人/泊展科技, legal name Shanghai Bozhan Technology Co., Ltd.) is a Shanghai-based company that builds autonomous underwater robots for cleaning and inspecting ship hulls in commercial ports. Founded in 2017 by a team with engineering backgrounds in aerospace equipment, automotive manufacturing and underwater operations, the company has focused on moving hull-cleaning robots from remote-operated devices toward autonomous, industrial-grade systems.
Its flagship product is the Metis underwater hull-cleaning system, which uses high-precision underwater positioning, AI-based path optimization, cavitation jet cleaning and turbid-water imaging to remove biofouling from ship hulls without divers. The company says Metis can complete a hull cleaning job in hours rather than the days typically required for diver-based cleaning, and the system includes 3D hull reconstruction and digital reporting of cleaning results.
Botzan has conducted real-ship trials in Chinese ports including Ningbo, Guangzhou Nansha, Beibu Gulf and Qingdao, and has a partnership with a Singapore-based marine services operator. It exhibited at the Sea Asia maritime trade show in Shanghai in 2025. In November 2026 the company raised a tens-of-millions-of-yuan institutional funding round led by Daotong Investment (道彤投资), with participation from an investor referred to as Shida Bo (世达舶), to fund product R&D, scaled production and expansion of its global service network.
