👉 The fluid in robots, often referred to as soft robotics or compliant actuators, is a flexible and deformable material that enables robots to move and interact with their environment in a more natural and adaptable way. Unlike traditional rigid robots, which rely on hard components like metal frames and gears, fluid-based robots use chambers filled with liquids or gels that can change shape when pressurized or pumped. This allows for smooth, continuous motion and the ability to navigate complex terrains, handle delicate objects without damage, and even mimic biological movements such as crawling or swimming. The fluid's properties also make these robots inherently safer for human interaction, as they can conform to unexpected obstacles and reduce the risk of injury.
