Scientists at Stanford University in California have created a robot – named ‘OceanOneK’ by them – that can dive deep into the ocean to locate shipwrecks and sunken planes. The robot, which has a predecessor, ‘OceanOne’ (2016), was built out of a desire to study coral reefs within the Red Sea, and beyond the reach of divers, reported CNN.
Here's all you need to know about OceanOneK:
(1.) Shape and structure: Essentially a humanoid, the OceanOneK resembles a human diver from the front; it has arms, hands, and eyes with 3D vision. On the back, it is equipped with computers and eight multidirectional thrusters that help it reach the sites of sunken ships.
The robot has a height of 5 feet (1.5 metres) and is built to handle objects without breaking them.
(2.) How does it work: Though the machine is controlled by an operator, it is also fitted with sensors and algorithms so that it can function automatically and avoid collisions.
Also, as OceanOneK has a touch-based feedback system, the person operating it feels as if he/she is underwater as well.
(3.) Reach and modifications: While OceanOne has a maximum reach of 656 feet (200 metres), its successor was created with a new goal: 1 km or 1,000 metres (0.62 miles), and hence the name ‘OceanOneK’.

(4.) Challenges: In February, during a deep dive, when scientists stopped for a thruster check, they discovered that the robot couldn't ascend. This happened because flotations on the communication and power lines collapsed, resulting in the line piling on top of the robot.
(5.) Missions accomplished: The machine has, so far, explored a sunken Beechcraft Baron F-GDPV plane, Italian steamship Le Francesco Crispi, a second century Roman ship off Corsica (1,095 feet/334 metres), a World War II P-38 Lightning aircraft and a submarine called Le Protée (406 feet/124 metres).
