Biomimicry is the idea of imitating God’s creation design. Here’s an example: Engineers have designed a robotic arm based on octopus tentacles.

Two-thirds of an octopus’s neurons are in its arms. Neurons are cells that send nerve signals. You might say each arm has a mind of its own. Octopus arms can untie knots, open childproof bottles, and wrap around prey of many shapes and sizes.

The hundreds of suckers that cover tentacles can form strong seals even on rough surfaces underwater.

Researchers at Harvard and Beihang Universities developed the octopus-inspired soft robotic appendage. It can grip, move, and manipulate a wide range of objects.

Its flexible, tapered design comes complete with suction cups. They give the gripper a firm grasp on objects—everything from eggs to iPhones to large exercise balls.

Researchers began by studying the tapering angle of real octopus tentacles. They figured out a design that would work best for bending and grabbing. They also figured out the best arrangement of the ‘suckers.’ Two valves control the Festo Tentacle Gripper. One applies pressure for bending the arm. Another creates the vacuum for the suckers. By changing the pressure and vacuum, the arm can attach to an object, wrap around it, carry it, and release it.

Designers tested the device on many different objects. They tried it on thin plastic sheets, coffee mugs, test tubes, eggs, and even live crabs. They probably even tried it on themselves! Wouldn’t you?

The team learned a lot about designing soft robotics. They also learned a lot about how God designed the octopus.
