Buoyancy-driven robots

Definition

Buoyancy-driven robots are autonomous machines designed to navigate underwater environments by utilizing buoyancy changes for locomotion. These robots typically rely on controlled buoyancy adjustments, allowing them to ascend or descend in the water column, which can be crucial for tasks like exploration, environmental monitoring, and underwater inspections. By harnessing the principles of buoyancy, these robots can move efficiently and effectively through water, often requiring less energy compared to traditional propulsion methods.
