Researchers from Gazi University in Turkey created an untethered robot without any electronics by coating paper with a mixture of silicon resin and iron particles. Carrying a sensor for detecting heavy metals, the magnetically controlled robot can move towards a sample and test it for contamination. Published in ACS Applied Materials and Interfaces, this work highlights an emerging class of soft robots that are both multifunctional and constructed from simple materials.

There is no need for electronics in this 3D-printed gripper! ??? UC San Diego researchers have developed an innovative soft robotic gripper powered by compressed air rather than electricity. A pneumatic device with a series of valves can grasp and release objects, offering potential applications in handling fragile items. ?? ?? Bit of facts about this innovative gripper! → The device was developed by a team of roboticists at the University of California San Diego, in collaboration with researchers at the BASF corporation. → The gripper can pick up, hold, and release objects using built-in gravity and touch sensors without needing electronics. → The researchers designed a fluidic logic system that allows the robot to remember when it has grasped an object and is holding on to it, releasing it when it detects the object's weight pushing to the side. ? Question: What potential applications do you see for this electronics-free gripper? ~~~ ?? Repost to help 1 robot find a new workplace. https://lnkd.in/eKvAk-cz

Exploring Light-Induced Changes in Cellulose at the cSAXS beamline. ? ?? Cellulose structures that respond to light can be used to generate movement with potential application in soft robotics. ? In today’s #SciencePic, Jonathan Avaro closely examines the setup during beamtime at the cSAXS beamline of #SwissLightSource #SLS. The experiment, led by Empa, uses X-ray scattering to investigate how specially designed cellulose changes structure in response to blue light. ?

Kirigami-Inspired Metasheet Robots! These robots represent a significant advancement in microscale robotics, combining principles from the Japanese paper-cutting art with advanced materials science. These robots, developed by researchers at Cornell University, are printed as 2D hexagonal "metasheets" less than 1 millimeter in size. When exposed to an electric current, they can fold into complex 3D shapes and perform locomotion, mimicking biological organisms. The metabots utilize a kirigami structure that spans five orders of magnitude in length, from 10 nm electrochemically actuated hinges to 100 μm splaying panels. This design allows for rapid shape transformations, with the ability to expand and contract by 40% within 100 ms.

Liquid crystal dielectric elastomers (LC-DEs) enhance the adaptability of dielectric actuation modes in comparison to traditional dielectric elastomers (DEs). By utilizing thermally triggered shape-changing, LC-DEs can switch between two shapes with distinct bending stiffness, enabling versatile actuation modes upon the application of an electric field. These shapes are individually programmable/reprogrammable, achieved through force-directed solvent evaporation and bond exchange-enabled stress relaxation. This innovative approach allows for multimodal dielectric actuation behaviors, responsive to temperature changes, and offers practical applications in soft robotics with reduced driving electric field requirements.

Congratulations to Hayden Webb, a robotics research assistant in Kaiyu Hang’s?RobotPi Lab! His Roller Rings device won third place in the international Student Mechanism and Robot Design Competition organized by the American Society of Mechanical Engineers. Webb's invention is a modular attachment with active surfaces that can be worn by existing robot (or human) hands. The attachment enables "in-hand manipulation,” such as rolling, sliding, and breaking and remaking contact. https://bit.ly/4dOqzAY
