Researchers from the University of Georgia have published a new study based on the design of a soft robotic gripper inspired by twining plants.
The team, led by associate professor Mable Fok, UGA College of Engineering, claim that their soft robotic gripper offers several advantages over existing robots thanks to its twining motion inspired by pole beans.
While pole beans and other twining plants use their touch-sensitive shoots to wrap themselves around supports like ropes and rods to grow upward, the team’s robot is designed to firmly but gently grasp objects as small as 1mm in diameter.

Scientists often look to nature for cues when designing robots - some robots mimic human hands while others simulate the actions of octopus arms or inchworms. Now, researchers in the University of Georgia College of Engineering have designed a new soft robotic gripper that draws inspiration from an unusual source: pole beans.
While pole beans and other twining plants use their touch-sensitive shoots to wrap themselves around supports like ropes and rods to grow upward, the UGA team s robot is designed to firmly but gently grasp objects as small as 1 millimeter in diameter. We had tried different designs but we were not happy with the results, then I recalled the pole beans I grew in our garden few years ago, said Mable Fok, an associate professor and the study s lead author. This plant can hold onto other plants or rope so tightly. So, I did some research on twining plants and thought it was a good design from nature for us to explore.
