Power-efficient underwater robotic rises and falls through fuel-cell balloons
If scuba divers use inflatable BCDs (buoyancy management units), why do not underwater robots? Effectively, an experimental new one does, and the expertise is claimed to be far more energy-efficient than conventional strategies of shifting up and down within the water. Ordinarily, underwater ROVs (remotely operated automobiles) and AUVs (autonomous underwater automobiles) are designed to…
