This study introduces a novel soft buoyancy gripper for underwater robots. This adaptable gripper controls buoyancy and grasps objects using internal fluid modulation, enabling safer marine exploration.
Area of Science:
- Robotics
- Marine Engineering
- Soft Robotics
Background:
- Underwater soft robots are emerging as safer, more adaptable alternatives to rigid robots.
- Their flexible nature allows for easier navigation and interaction in complex aquatic environments.
Purpose of the Study:
- To present a novel soft buoyancy gripper for underwater applications.
- To demonstrate a system capable of managing buoyancy and grasping objects without external mechanisms.
Main Methods:
- A soft gripper design utilizing internal fluid volume modulation.
- Integration of a buoyancy control system within the soft robot.
- Experimental validation of grasping, object manipulation, and locomotion capabilities.
Main Results:
- The soft buoyancy gripper successfully grasped and released various objects.
- Adjusting internal fluid volume allowed for both gripping and buoyancy control.
- Addition of a channel enabled a crawling motion, showcasing versatility.
Conclusions:
- The developed soft buoyancy gripper offers a versatile and adaptable solution for underwater exploration and research.
- Its design minimizes harm to marine environments and organisms, making it suitable for sensitive research applications.

Rigid Body Equilibrium Problems - II
Consider two children sitting on a seesaw, which has negligible mass. The first child has a mass (m1) of 26 kg and sits at point A, which is 1.6 meters (r1) from the pivot point B; the second child has a mass (m2) of 32 kg and sits at point C. How far from the pivot point B should the second child sit (r2) to balance the seesaw?
