“…In addition, among several common drive methods, gas drive and electric field drive have ropes, [30][31][32][33][34][35] which limit the usage scenarios and distance of soft robots. Optical drive and thermal drive exhibit slow response time, [14,36] which affects the motion efficiency of the soft robot.…”

Bio‐inspired micro soft robots mimic biologically specific body structures and movement mechanisms by utilizing bionic principles. Because of its soft body, it can adapt to complex external environments. However, the existing polymer material system is single and the fabrication process is limited. How to further reduce soft robot size has become a key issue. In this work, a Programming Magnetic Elastic Composites (PMEC) is proposed for 3D printing to manufacture micro soft robots. The PMEC has the advantage of changing the direction of the internal magnetic field in response to changes in the external magnetic field. A Microsoft robot is designed and fabricated using PMEC inspired by an inchworm. Numerical simulations are also used to study the effect of soft robot size parameters on local stresses and optimize the structure. The results show that the microscale soft robot can crawl with a load of 2 times its weight at a speed of 6.67 mm s−1, crawl on slopes from 0° to 90°, and crawl over obstacles with a maximum height of 7 mm. In addition, active adaptation of soft robots to complex tunnel models based on external stimuli is achieved by magnetic field control.

“…This tool, with its finely tuned structural parameters, showcases a remarkable 12.8% reduction in energy consumption, enhances efficiency by 12.5%, and possesses a cutting force 1.54 times greater than conventional tools [4]. Through studying Venus flytraps' morphology, microstructure, and kinetics, chamber design principles were established and a pneumatic biomimetic blade was successfully created [5], yielding commendable results. Jia's [6] analysis of locust mandible tooth shapes culminated in the creation of a biomimetic saw blade.…”

Diamond circular saw blades, integral in industries such as aerospace, nuclear energy, and construction engineering, face challenges including high cutting forces and significant tool wear, which often fall short of modern engineering requirements. To address these issues, this study explores the application of the non-smooth morphology, inspired by the surface of Scapharca subcrenata, known for their friction-reducing and wear-resistant properties. This morphology is applied to the tool-chip contact area of the saw teeth. Comparative experiments, conducted through sawing simulations, reveal that the optimized tool demonstrates improvements in sawing force, equivalent stress, and material removal rate compared to conventional tools. These findings offer valuable insights for further research into the wear resistance and drag reduction optimization of diamond circular saw blades.

Nature abounds with examples of ultra-sensitive perception and agile body transformation for highly efficient predation as well as extraordinary adaptation to complex environments. Flytraps, as a representative example, could effectively detect the most minute physical stimulation of insects and respond instantly, inspiring numerous robotic designs and applications. However, current robotic flytraps face challenges in reproducing the ultra-sensitive insect-touch perception. In addition, fast and fully-covered capture of live insects with robotic flytraps remains elusive. Here we report a novel design of a robotic flytrap with an ultra-sensitive “trichome” and bistable fast-response “lobes”. Our results show that the “trichome” of the proposed robotic flytrap could detect and respond to both the external stimulation of 0.45 mN and a tiny touch of a flying bee with a weight of 0.12 g. Besides, once the “trichome” is triggered, the bistable “lobes” could instantly close themselves in 0.2 s to form a fully-covered cage to trap the bees, and reopen to set them free after the tests. We introduce the design, modeling, optimization, and verification of the robotic flytrap, and envision broader applications of this technology in ultra-sensitive perception, fast-response grasping, and biomedical engineering studies.
