Marine embodied-intelligence firm Shaanxi Weilang Deep Sea Information Technology has announced a new funding round backed by Shenzhen Capital Group, Oriza Holdings and Guocai Capital, with existing investor InnoAngel adding more capital.
The round reached the “angel-plus-plus-plus” stage, meaning Weilang has now completed five consecutive financing rounds in nine months.
Founded in September 2021, Weilang grew out of Xi’an Jiaotong University’s deep-sea equipment team, under the university’s marine technology and equipment innovation institute. It is a technology-transfer company backed by the Qinchuangyuan seed fund.
Founder Zhang Dayu is a XJTU PhD and assistant professor with 12 years in unmanned underwater systems. The chief technology officer comes from China State Shipbuilding and has led more than ten national major projects with total funding above RMB 2 billion.
The core product is the “Super Frogman” marine embodied-intelligence robot, built from a general underwater-robot platform and a “seabed starlink base” module.
The general platform uses acoustic-optical-magnetic cross-scale sensing fusion, with positioning error under one metre and target-recognition accuracy above 95 per cent. It carries twin 6-degree-of-freedom arms, a payload above 10 kg, 48-hour endurance and a top speed of 12 knots.
The “seabed starlink base” solves ultra-low-flow power generation, producing energy steadily at flows as low as 0.1 metres per second, giving underwater robots both power and communications support.
The company runs a “general platform plus modular payload” architecture, training through real-operation data pipelines, and has already delivered fully autonomous subsea energy-facility inspection to marine clients.
The new funds will train underwater embodied-AI models, build an underwater embodied-AI training centre, and deepen robot use in offshore oil and gas. Five rounds in nine months put Weilang at the front of underwater-robot financing, with Shenzhen Capital and peers betting on the certainty of robots replacing humans in offshore energy.
