Chameleon Tongue Inspires Fast-Acting Soft Robots

Chameleon Tongue Inspires Fast-Acting Soft Robots
The impressive elastic tongue of the chameleon has inspired a new class of high-speed soft robots and actuators.

The soft robotics, developed by a team from Purdue University, are made up of stretchable polymers embedded with pneumatic channels that will expand when pressurized. The robots’ elastic energy is stored by stretching its body during fabrication, resulting in a soft robot able to expand five times its length to catch and retrieve a live fly beetle in only 120 milliseconds.
