Chameleon's tongue strike inspires fast-acting robots
Ramses Martinez, an assistant professor in Purdue's School of Industrial Engineering and in the Weldon School of Biomedical Engineering in Purdue University's College of Engineering and other Purdue researchers at the FlexiLab have developed a new class of entirely soft robots and actuators capable of re-creating bioinspired high-powered and high-speed motions using stored elastic energy.
A video showing this insect-catching robot: Many birds, like the three-toed woodpecker, achieve zero-power perching using the elastic energy stored in the stressed tendons at the back of their legs, allowing them to not fall off a perch when asleep.
The anatomy of these birds has served as an example to enable the fabrication of robotic grippers capable of zero power holding up to 100 times their weight and perching upside down from angles of up to 116 degrees.
Inspired by the trap mechanism of the Venus flytrap and studying how lizards catch insects, the Purdue team created a soft robotic Venus flytrap, which closes in only 50 milliseconds after receiving a short pressurized stimulus.

Knots form not only in everyday items such as headphone wires, but also in less-tangible realms, from electromagnetic field lines to the quantum states of electrons in solids.
Then, using a magnetic field, the scientists aligned the magnetic axis of the gas along curves that twist — like a skewed bundle of spaghetti — around a series of doughnut-shaped surfaces, which are nestled inside one another.
Bugs Begone: Chameleon Tongue Inspires Fast-Acting Robots With Flash-Like Reflexes
A team of researchers from Purdue University is taking cues from nature to inspire fast-acting robotics with chameleon-like reflexes capable of grabbing and maneuvering items with astonishing speed.
(Tell that to the fruit flies haunting your kitchen.) “We believed that if we could fabricate robots capable of performing such large-amplitude motions at high speed like chameleons, then many automated tasks could be completed more accurately and in a much faster way,” said study author Ramses Martinez in a statement.
Publishing their work in Advanced Functional Materials, the researchers say that their biologically inspired robotic grippers are capable of holding up to 100 times their own weight while perching upside down from angles of 116 degrees – much like a woodpecker perches on a tree while sleeping or hunting for food.
'We envision that the design and fabrication strategies proposed here will pave the way toward a new generation of entirely soft robots capable of harnessing elastic energy to achieve speeds and motions currently inaccessible for existing robots,' said Martinez.
