Armach Robotics launches Hull Service Robot – Digital Ship

Armach Robotics, a spin-off from marine software company Greensea Systems, has unveiled its first post-prototype Hull Service Robot (HSR).

The HSR is a proactive, subscription-based robotic hull cleaning system using autonomy, intelligence and data fusion.

The robot weighs less than 66 lbs (30 kg) and is approximately 34 inches (86 cm) long, making it easily portable and significantly reducing deployment costs.

The robot recently launched for its first in-water trials in Plymouth, Massachusetts, marking an important step in proactively transforming water cleaning into a viable solution to save fuel and optimize vessel performance.

“My favorite job in this industry is working on next-gen systems. The team learns so much in developing and testing a product for a new application, but once a vehicle is functional enough, the pace design evolution slows significantly. Designing the next generation, once you have a good understanding of the requirements and have developed proven key components, is an incredible opportunity,” said James Truman, vice president of engineering at Armach.

The original prototypes consisted of off-the-shelf navigation systems, a custom tracked skid and a separate ROV, all bolted together, but as Truman explains, there were more efficient ways to integrate this equipment into the vehicle. finalized.

“It worked well in prototypes, but it was expensive and clumsy,” he said. “For the purpose-built Armach HSR, we removed much of the structural and electrical overhead from the prototypes. This gave us a smaller, lighter and more streamlined vehicle that can operate in faster water currents and on low friction surfaces. We have performed extensive testing to minimize the impact of the hull coating and will continue accelerated life testing and design iteration to ensure long-term reliability.”

For the HSR vehicle, Armach designed and produced the electromechanical drive and cleaning components in-house, as it required not only high power density and unique packaging, but also precision control and feedback.

Greensea has considerable experience in intelligent control systems for underwater robots. The vehicle is specially designed around state-of-the-art miniaturized navigation sensors. Greensea’s Opensea merges a navigation solution from a myriad of sensors and provides rock-solid vehicle control.

For the HSR vehicle, Armach designed and produced the electromechanical drive and cleaning components in-house, as it required not only high power density and unique packaging, but also precision control and feedback. This approach pays off in terms of usability and control in the water, as well as the quality of the hull data returned: “The resulting driving performance on a hull as well as the stability in free flight is incredible. The networked architecture and SAFEC2 functionality means we can monitor or control vehicles from anywhere in the world,” said Truman.

The robot offers shipping companies a proactive and autonomous robotic in-water cleaning solution. The technology is non-coating specific and is based on a state-of-the-art system, powered by Greensea’s autonomy, intelligence and data fusion technologies. Armach’s business model provides cleaning robots to ships, ports, harbors and established service providers on a monthly subscription basis.
