Snatcher Robot Chameleon Tongue
Researchers at Seoul National University of Science and Technology (SeoulTech), led by Gwang-Pil Jung, have developed a weird Snatcher robot that comes equipped with a robotic arm that shoots out like a chameleon’s tongue. Measuring just 12 x 8.5 x 8.5 centimeters and weighing in at 120 grams, the robot’s tongue is capable of grabbing 30 grams from 80 centimeters away in under 600 milliseconds.



To build this robot, the team first had to develop a spring-like device controlled by an active clutch combined with a single series elastic actuator. The chameleon’s tongue passes through two geared feeders that are powered by a wind-up spring. What they ended up with was an ultra lightweight robot capable of retrieving objects 0.8 meters away within 600 milliseconds.

Snatcher Robot Chameleon Tongue

Our final goal is to install the Snatcher to a commercial drone and achieve meaningful work, such as grasping packages. To solve this issue, we are finding materials having high energy density. We are planning to make a bi-stable gripper to passively grasp a target object as soon as the gripper contacts the object,” said Gwang-Pil Jung, a researcher at Seoul National University of Science and Technology (SeoulTech).
