Deep Sea Robots

The deep sea: a fascinating place!
Extremely harsh environment: cold, dark, immense pressure
Difficult, dangerous, and expensive to send humans down there
Instead, build a machine that can dive into the deep sea and send back pictures and data.
ROV = Remotely Operated Vehicle
ROV pilots and scientists can sit in a warm, safe place while the ROV is deep in the ocean, sending back LIVE video and data.
