Armach Robotics, a Greensea Systems affiliate, has introduced its first post-prototype hull service robot, says an article published in Riviera.
Navigation systems
This 30-kg, 86-cm-long unit was tested underwater on a ship hull in Plymouth, Massachusetts.
It is a smaller, smarter, and more efficient unit than the original prototypes Armach built, which used off-the-shelf navigation systems, a specialised crawler skid, and a separate ROV put together.
Streamlined vehicle
“It worked well in the prototypes but was expensive and clunky,” says Armach vice president of engineering James Truman.
“For the purpose-built Armach HSR, we stripped out a lot of the structural and electrical overhead from the prototypes,” he explains.
“That gave us a smaller, lighter, and more streamlined vehicle that can operate in faster water currents and on lower friction coatings. We have tested extensively to minimise hull-coating impact and will continue accelerated life testing and design iteration to ensure long-term reliability.”
Precision-control
This HSR has Greensea’s OpenSea miniaturised navigation sensors and precision-control processing, as well as an electro-mechanical drive, in-house cleaning components, and remote monitoring and control functions.
