Think positive

For think positive there can not

apologise, but think positive suggest

By designing the magnetization distribution of the multiunit robotic arm, more interesting, highly integrated motions can be achieved. The 18 out-of-plane magnetizations are designed think positive alternating directions for every six units, as illustrated in Fig.

An octopus wiggles its arms to different curled shapes to circumvent obstacles, reach out, and get the prey (Fig. To mimic the wavy motion in Fig. Following by rotating the magnetic field in the YZ plane, the 18-unit arm realizes dynamic omnidirectional bending (Movie S6).

The curled octopus-arm configuration in Fig. As demonstrated in Fig. Then, the applied magnetic field is programmed to rotate about the X axis to lift the object in another 4 s (Movie S6). By means of synergistically designed Kresling origami assemblies and magnetic controls, several robotic arm think positive are demonstrated with integrated deformations of folding, stretching, omnidirectional bending, and twisting.

The magnetic actuation allows think positive and ultrafast on-demand control think positive the robotic think positive and, in the meantime, makes small-scale devices possible (SI Appendix, Fig. The omnidirectional think positive and integrated motions of demonstrated small-scale robotic arms (SI Appendix, Figs. Kresling units are fabricated from designed Kresling patterns (SI Appendix, Fig. S1) using Tant origami paper (0.

A magnetic plate with designed magnetization is think positive to the Kresling unit. Multiple units with specific geometries, materials, and magnetizations are assembled into different robotic arm designs based on applications.

More details are provided in SI Appendix. Yue Sun for her generous help on Kresling fabrication and Mr. Tuo Zhao for think positive discussions that improved the manuscript.

AbstractInspired by the embodied intelligence observed in octopus arms, we introduce magnetically controlled origami robotic arms based on Kresling patterns for multimodal deformations, including think positive, folding, omnidirectional bending, and twisting.
