Nature inspired innovation done by a South Korean research team can handle soft to tough tasks and even assists in surgery thereby catalysing robotics applications across fields.
A team of roboticists and engineers from South Korea, in collaboration with the Max Planck Institute for Intelligent Systems, has developed a soft, X-shaped robot capable of handling both delicate and rigid objects in diverse environments.
The robot, designed to work seamlessly in slippery, jellied, and mucus-like conditions, uses magnetic control to move and manipulate various materials. Constructed from a composite polymer combining polydimethylsiloxane (PDMS) matrix and NdFeB particle fillers, the robot was crafted into its X shape using a 3D printer and casting techniques. Its innovative design includes octopus-inspired suction grippers on its legs for enhanced adhesion and manoeuvrability.
“Testing showed the robot capable of adhering to a wide variety of targets, whether they were wet, oily, gooey or dry,” the researchers noted. The device’s inspiration comes from the velvet worm, which immobilizes prey using secretions that harden on contact. Similarly, the robot employs magnetorheological elastomers to modulate its adhesive properties.
The innovation holds significant potential for a wide range of audiences. Medical professionals could use it for intricate surgical tasks, as demonstrated by the robot’s ability to remove a cancerous tumor from a live mouse. Additionally, industries requiring precise manipulation of soft or slippery materials, such as food processing or electronics, might also benefit from this versatile design.
The robot demonstrates remarkable versatility, successfully handling tofu, fish organs, and even mechanical tasks like screwing and unscrewing bolts. By merging nature-inspired mechanics with cutting-edge materials, this innovation exemplifies how soft robotics is advancing in functionality. The researchers believe their creation could open avenues for further advancements in bioinspired robotics, offering practical solutions for medical and industrial challenges.
With its ability to adapt to diverse conditions and manipulate a wide variety of objects, this X-shaped robot is a promising step forward in the field of soft robotics.
