RobotPlusPlus announces Series C funding for industrial robots working at height

Capital for a specialized industrial business

RobotPlusPlus announced a Series C round worth hundreds of millions of renminbi on September 16. It did not disclose an exact amount. Qianggang Capital Fund led the financing, joined by GIG Capital Group, Sealand Innovation and Juntong Capital, while existing investor Fosun RZ Capital increased its investment.

The company builds machines for hazardous maintenance work, including inspection, surface preparation, coating and cleaning. Its announcement identifies international service networks, manufacturing and embodied-AI development as uses for the funds.

The maintenance task comes before the robot form

Ship-hull work helps explain the product strategy. A vessel's steel surface needs preparation before a coating can perform as intended. The commercial objective is a finished surface that meets the customer's requirements, so a robot must be evaluated together with its operating equipment, inspection process and crew.

In the financing release, RobotPlusPlus claims deployments at more than 100 shipyards and work on over 10,000 cargo vessels. It also claims faster work and lower costs than manual methods. Those figures are attributed to the company; the release does not provide an independent comparison with a defined sample of shipyards.

A later product announcement makes the application concrete

A September 23 company release adds detail on the HighMate systems shown at SMM in Hamburg. RobotPlusPlus describes a coating robot that attaches to steel with permanent magnets, follows curved surfaces and uses two spray nozzles. It claims a production rate of 300–500 square meters per hour and says a recovery system collects overspray. These are supplier specifications, with no independent test presented in the release.

The same announcement describes an AP Ex platform with interchangeable cleaning, coating and blasting modules, alongside cargo-hold cleaning and hull surface-preparation machines. It illustrates how the company is building several products around related maintenance jobs, rather than offering a single machine for every industrial task.

This detail helps explain what the financing is intended to scale. Coating and surface preparation are adjacent stages, but they require different tools and acceptance checks. A customer may need a coordinated set of machines and operating procedures. The company's ability to deliver and support that complete process will be more informative than the number of different robot models in a catalog.

Where international demand is coming from

The financing announcement names NOSCO Shipyard in Vietnam, Drydocks World in Dubai and ST Engineering Marine in Singapore among customers or partners. It describes a multimillion-dollar NOSCO order and a presence in more than 18 countries. These are company disclosures, not separate statements obtained from those operators.

The geography matters to the service plan: machines used in a dry dock need parts, consumables and technical support near the job. A supplier can sell the same platform internationally while still needing local installation and training. The release does not break out revenue by customer or region.

What scaling would mean for customers

A robot sold into another country needs installation, operators, maintenance and replacement parts. For industrial buyers, the ability to restore a machine to service can matter as much as its performance during a demonstration. The announced investment in a sales and service network is therefore relevant to the practical delivery of the product.

The funding is evidence that investors are backing this specialized approach to robotics. It is not evidence that all work at height can be automated or that each customer will achieve the same savings. A useful customer assessment would compare completed work, downtime and the full operating cost on a specified surface and job.
