Technological innovations and future trends in underwater robots for marine cable inspections.
| Technology | Description | Benefits | Future implications |
|---|---|---|---|
| Bionic Propulsion [81] | Nature-inspired propulsion systems replicating the movement of marine animals like fish and jellyfish. | Lower noise, increased maneuverability, higher energy efficiency, better agility in confined spaces. | Facilitates quiet, effective, and versatile mobility in intricate underwater environments. |
| AI and Deep Learning [82] | Integration of AI algorithms to process large amounts of data and make autonomous decisions during inspections. | Autonomous decision-making, improved prediction of cable failures, more efficient routing. | AI-driven robots for real-time decision-making, reducing human involvement, and streamlining inspection operations. |
| Sonar Technology (Multi-Beam Sonar) [83] | Enhanced sonar systems that provide high-resolution imaging of cables and seafloor for accurate mapping. | More resolution, greater depth perception, greater cable tracking, and fault detection. | Improved accuracy in deep-sea inspection to facilitate real-time accurate mapping and maintenance. |
| Multisensory Fusion [84,85] | Combining data from different sensors (sonar, cameras, accelerometers) to improve robot navigation. | Improved navigation in poor underwater conditions, higher positioning accuracy. | Hybrid navigation systems which enhance the reliability of the robot, particularly in challenging environments. |
| Hybrid Navigation Systems [86] | Integration of acoustic, visual, and inertial navigation data for precise positioning. | More accurate navigation, dependable operation in the face of environmental noise. | Facilitates effective navigation with fewer inspection errors, increasing the precision of cable monitoring. |
