A Programmable Inchworm-Inspired Soft Robot Powered

With the growing demand for miniaturized workspaces, the demand for microrobots has been increasing in robotics research. Compared to traditional rigid robots, soft robots have better robustness and safety. With a flexible structure, soft robots can undergo large deformations and achieve a variety of motion states. Researchers are working to design and fabricate flexible robots based on biomimetic principles, using magnetic fields for cable-free actuation. In this study, we propose an inchworm-shaped soft robot driven by a magnetic field. First, a robot is designed and fabricated and force analysis is performed. Then, factors affecting the soft robot’s motion speed are examined, including the spacing between the magnets and the strength and frequency of the magnetic field. On this basis, the motion characteristics of the robot in different shapes are explored, and its motion modes such as climbing are experimentally investigated. The results show that the motion of the robot can be controlled in a two-dimensional plane, and its movement speed can be controlled by adjusting the strength of the magnetic field and other factors. Our proposed soft robot is expected to find extensive applications in various fields.

JBE|Recent Progress in Bionic Hydrogels for Articular Cartilage

Cartilage regeneration and repair are considered clinical challenges since cartilage has limited capability for reconstruction. Although tissue-engineered materials have the ability to repair cartilage, they have weak mechanical characteristics and cannot resist long-term overload.
