What are the important design features of underwater robots?

The important design features of underwater robots are as follows:

• Pressure resistant mechanism: Underwater robots should have a pressure resistant mechanism to handle extreme water pressure while working in the depths of oceans.
• Buoyancy control: The robot should be able to control its buoyancy by using different buoyancy control mechanisms.
• Propulsion system: Underwater robots should have a propulsion system to help them move in water. It can be achieved by using thrusters, propellers, or other propulsion systems.
• Cameras and sensors: Underwater robots consist of cameras and sensors which help them to navigate in underwater environment. The sensors used may be sonar, depth sensors, or other imaging devices.
• Manipulator arms: Manipulator arms are used to perform various tasks, like collecting objects, manipulating objects, mining, or repairing.
• Communication system: A communication system is required to communicate with the operators. It may be achieved by using wireless or tethered cable communication systems.
• Power source: Waterproof batteries and cells are used as a power source to operate underwater robots.
• Control system: A robust control system is required to control the operations of underwater robots.
• Materials: Underwater robots are made up of materials like titanium, stainless steel, and polymers which can handle environmental factors in the ocean.
