According to foreign media NnewAtlas, when you think of robots, you may not think of elastic meshes that can float on the water, but this was developed by researchers at North Carolina State University. These soft structures are 3D printed and embed magnetic particles that can be stretched and compressed to grab and move small objects. To make these "robot" grids, the team first mixed the "ink" made of silicon beads, liquid silicon, water and important carbonyl iron particles. These things can then be 3D printed into a variety of meshes and then cured in the oven to form a soft, flexible structure. These "robots" can float like water on the surface of the water. To control the structure, the team can change the magnetic field, adjust the intensity up and down or turn it on and off. For example, opening the magnetic field may cause the mesh to roll toward one end and then bounce back to its original size when the area is closed again. By changing the size and shape of the grid, the team was able to create a number of different "robot" designs for a variety of purposes. In one example, the researchers created a spring-like gripper with a "gripper" on one end. When the magnetic field is turned on, the springs are partially gathered and used to drag the "hand grip". By opening and closing, the researchers were able to extend the "hand" and grab a small aluminum ball and drag it in. In another example, the researchers made a large, flat sheet with more "lines" in between. When the magnetic field is turned on, the mesh shrinks toward the center, leaving it with a drop of water on its surface. But turning off the magnetic field, the mesh stretches to its full size, allowing the droplets to fall into the water below. This design allows for liquid transport and can be mixed as needed. Orlin Velev, the author of the study, said the study showed the ability to combine emerging areas of 3D printing with flexible robots, an early proof of concept for flexible robotic actuators. The study was published in the journal Advanced Materials Technology. 63Mm Neck Size Jar Preform,63Mm Wide Mouth Preform,63Mm Wide Mouth Jar Preform,63Mm Jar Preform Heshan Yecheng Plastic Product , https://www.plasticpreform.com
