Spongey Pads: Enabling Robots to Fine-Tune Grasp Strength in the Future
Introduction:
Introducing a groundbreaking system that could revolutionize the capabilities of robotic graspers. Developed by scientists at the University of Bristol, this sponge-based technology allows for a versatile grasper that can switch between securely lifting heavy objects and delicately handling fragile items. Inspired by the structure of human fingers, the system features hard mechanical pincers with spongey pads on the inside ends. These pads are made of silicone sponge material encased in an airtight polymer skin and connected to an air pump. By adjusting the air pressure, the pads can expand to a squishy consistency for gentle contact or compress to a thin and stiff state for a firmer grasp. This innovation has the potential to enable industrial robots to handle fragile objects and reduce the risk of accidental injuries when used in service robots interacting with humans. With its low cost and lightweight design, this system opens up a world of possibilities for the future of robotics.

How a Sponge-Based System Could Enhance Robotic Graspers
Robotic graspers are known for their ability to either securely lift heavy objects or delicately handle fragile items. However, researchers at the University of Bristol have developed a new sponge-based system that allows a single grasper to switch between both functions seamlessly. Inspired by the structure of human fingers, this innovative setup could revolutionize the capabilities of industrial and service robots.
The Design: Combining Hard and Soft Components
The unique design of the system consists of a set of hard mechanical pincers, with each inside end covered by a spongey pad. These pads are made of silicone sponge material encased in an airtight polymer skin. A silicone hose connects each pad to an air pump.
Dual Functionality: Soft and Firm Grasping
By manipulating the air pressure within the pads, the grasper can alternate between a soft touch and a firmer grasp. When a soft touch is required, air is pumped into the pad, allowing it to expand to its full, squishy thickness. On the other hand, when a firmer grip is needed, air is drawn out of the pad. This negative pressure compresses the sponge, making it thin and stiff.
Potential Applications and Benefits
The researchers believe that this technology could prove valuable in various sectors. In the industrial field, existing robots could use the sponge-based system to handle fragile objects like eggs, reducing the risk of damage. Additionally, service robots that interact directly with people could employ this technology to minimize the chances of accidental injuries.
According to Dr. Tianqi Yue, the lead scientist behind the project, the key advantages of the sponge-based system are its low cost and light weight. This makes it an affordable and efficient device that can enable robots to achieve soft contact with objects, further enhancing their capabilities.
Conclusion
The introduction of the sponge-based system in robotic graspers opens up new possibilities for their functionality. By emulating the structure and adaptability of human fingers, this technology brings the advantages of both soft and firm grasping to robots. With its potential applications in various industries, this innovation has the potential to improve efficiency and safety in the field of robotics.
Summary: Spongey Pads: Enabling Robots to Fine-Tune Grasp Strength in the Future
Researchers at the University of Bristol have developed a new sponge-based system that allows a robotic grasper to switch between lifting sturdy objects and fragile items without breaking them. Inspired by the structure of human fingers, the system consists of hard mechanical pincers covered with spongey pads. By pumping air into the pads, they expand to provide a soft touch, and by drawing air out, they compress and become thin and stiff for a firmer grasp. This technology has the potential to enable industrial and service robots to handle delicate objects, reducing the risk of accidents.
