Buoyancy Control

Definition

Buoyancy control refers to the ability of a soft underwater robot to manage its buoyancy and maintain its position in water by adjusting its density relative to the surrounding fluid. This control is crucial for underwater navigation, as it allows the robot to ascend, descend, or hover at specific depths without expending unnecessary energy. By manipulating gas-filled chambers or using flexible materials, soft underwater robots can achieve precise movement and stability in aquatic environments.
