This soft robot imitates butterfly plants for creeping and climbing



Metal Vine

The soft robots have taken a page from the book about plants. The use of physical properties, similar to those found in plants, researchers at the Istituto Italiano di Tecnologia (IIT) in Genoa, Italy, has created a soft robot capable of sneaking and climbing, similar to the way plants do. Their research, published last week in the Nature Communications Nature Communications, may lead to a new generation of soft robots and wearable technology, such as bracelets capable of changing shape.

Often I do not think of movement in plants. One of the most often depicted examples of plant movement may be the closure of leaves in carnivorous mold of Venus. But many plant species move, their movement is simply focused on the direction in which they slowly grow. To drive their growth, plants use water transport or osmosis in their cells.

The IIT's soft robot, which has a flexible polyethylene body filled with liquid loaded with ions, mimics this process. When using a low voltage battery, the flow of electrically charged fluid in the robot may be directed to one side or the other. Liquid movement drives the robot to move into the apartment, allowing it to move and move like a plant vine. It's just enough to unscrew the robot by inverting the polarity of the charge.
