Biomedical engineers have developed a fast-moving robot that can use its tongue to catch insects. Their design was inspired by the flexible tongues of chameleons and salamanders. Engineers studied the elastic energy of these animals tongues and copied the motion principle to develop the soft robot.

The soft robot is made of stretch polymer similar to rubber band. The internal pneumatic channel can expand and pressurize. The soft robot can store elastic energy by stretching in one or more directions. Similar to chameleons spitting attack, the length of the pre stressed pneumatic soft robot can be increased by 5 times, and it can catch living insects in 120 milliseconds.

Professor Ramses Martinez, School of engineering, Purdue University, said: we believe that if we can make a robot to perform such a large scale of motion, its motion mode is very similar to that of a chameleon, then many automatic tasks can be completed more accurately and quickly. Traditional robots are usually made of hard and heavy components, because of the inertia effect I want to overcome this challenge.

Professor Martinez said that compared with the software robot developed before, this kind of pre-stressed software robot similar to the chameleon tongue has significant advantages. It is good at grasping and controlling various objects at high speed,

This software robot can hang upside down for a long time, which is convenient for catching flies, flying insects and other living insects.
