Choosing an underwater robot starts with the operating scenario, not only the product name. Buyers should compare depth rating, tether length, camera and lighting, stability, payload interface, control console, spare parts, training and delivery documentation.
Start from the job
Define whether the ROV will inspect aquaculture cages, reservoirs, tanks, bridge piles, dock walls, hulls, pipelines, environmental sites or search areas. The job decides the required depth, access method, camera package and payload path.
Check depth and tether margin
Confirm normal working depth, maximum depth and the distance from the operator to the target. Tether length and handling workflow often matter as much as depth rating.
Review camera, lighting and visibility
Clear water, muddy water, night work and close-range target confirmation need different camera and lighting choices. Low-visibility projects may require stronger lighting, turbid-water camera discussion or sonar-ready planning.
Plan payload and support
Manipulator arm, sonar, binocular camera, cleaning tool, USBL, DVL and payload brackets should be discussed before price comparison. They affect structure, operation and export package.
Compare quotation scope
Ask suppliers to clarify model, camera package, tether, control console, spare parts, warranty, manual language, OEM package, lead time and destination country support.
