For Marine & Research
Underwater Robot (ROV)
A tethered ROV for ocean exploration where it is too deep, dark, or dangerous for divers.
Capability: Robotics & AMR Development

The Challenge
Large parts of the ocean are too deep, dark, or hazardous for divers, yet researchers and operators still need to observe, document, and physically collect samples from the seafloor in real time.
From sketch to product
How we took Underwater Robot (ROV) from concept to a working build.
Define the dive
We scope depth, runtime, and payload (survey, inspection, or sample collection) to size the vehicle, buoyancy, and tether for the mission.
Design the vehicle
A compact ABS-plastic hull is designed to hover like an aerial drone over a seafloor target, carrying thrusters, an HD camera, and a manipulator arm.
Tether & control
A tether carries control signals, sensor data, and imagery between the vehicle and a rugged surface control station for real-time piloting.

Survey & sample
In the water, the pilot streams live HD video, records footage, and operates the arm to carry out targeted surveys, inspections, and sample collection.

Key features
Underwater inspection
Survey wide seafloor areas and inspect structures from a hovering, stable platform.
HD video recording
An onboard HD camera captures high-definition footage of the dive.
Live streaming
Real-time video and sensor data stream up the tether to the surface station.
Manipulator arm
A real-time pick-up arm carries out targeted collection and detailed experiments in the deep.
