This is not the first time that scientists have seen Mantis shrimp as a robot engineering inspiration. In 2021, we reported on the Harvard University researcher. Biological model For the powerful attached mantis shrimp, we have built a small robot to imitate the movement. The rare thing about Mantis SHRIMP is that there is a delay of 1 milliseconds when latching and snap action occur.
The Harvard Team has identified four different phases and confirmed that it is a geometry that generates rapid acceleration after the first liberation by the strong film. A short delay can help reduce latching mechanism wear by repeatedly.
New type movement
The operation principle of the high elastic torque reversal mechanism (HERTRM) is accompanied by compressing the elastomjotation until the accumulated energy reaches a critical point, which is instantaneously released.

KYU-JIN CHO, co-author of the Seoul National University, was interested in soft robot engineering as a graduate student when participating in the Robosoft Grand Challenge. Some of his research was to test the strength of the so -called “soft robot manipulator”, which is often used in the assembly line for welding and painting. He notices unintended deformation under the applied force, and the basic mechanism is how Mantis’s shrimp punches, or fleas are very high and far away from that size. I noticed that it was similar to how to do it.
in fact, Cho’s team Created earlier Nomi -style catapult mechanism In the case of a miniature jumping robot, he uses an excessive torque reversal mechanism developed by his lab. In order to abuse torque reversal, it usually includes complex mechanical ingredients. However, “I noticed that it was applied. [these] The principle of soft robot engineering may make it possible to create a new type of movement without complex mechanisms. ” Cho said。
At present, he was able to incorporate HETRM into a soft -robot arm that depends on material characteristics, not structural design. Basically, it is a soft beam with alternate over elasticity and rigidity segment.
“Our robot is made of soft and elastic material. Cho said。 “Inside, there is a special part of storing energy at a time and releasing everything at a time to move the robot very fast. This robot is high, crushing your hand, crossing the floor and CRA. You can even jump and just pull simple muscles.
