Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the vehicle designation?Remotely Operated Vehicle (ROV)
2. How does RuBot II stay safe in the deep ocean?It is built with strong materials like high‑strength alloys and special composites that can handle the huge pressure of the deep sea, and it is connected to a cable that gives it power and lets people control it from the surface.
3. Why do scientists use RuBot II instead of a human diver?The deep ocean is too dark and too pressurized for humans, so RuBot II can go there safely and let scientists take pictures, collect samples, and use instruments that need a human to guide them.

Remotely Operated Vehicle (ROV): An uncrewed, tethered underwater robot controlled by operators on the surface, used for exploration and work in hazardous environments.
Aphotic Zone: The portion of a lake or ocean where there is little or no sunlight, typically below 200 meters (656 feet).
Hydrostatic Pressure: The pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity.
