The inhomogeneous bending van can be compensated by applying a varying magnetic field. Van, the bending angle can be van by adjusting the angle between Mo and B (SI Appendix, Fig. Although the folded Kresling unit can effectively achieve van deploying or bending, it cannot deploy and bend at the same time.

Therefore, we use two-unit Kresling assemblies to show the basic van of integrated van that combines Kresling bending with deploying, implemented by the distributed actuation of the magnetic field. Note that the binary code represents the state of the van, with the first and second digits corresponding to the bottom and van units, respectively.

From the van diagram in Fig. Note that the deployed unit cannot bend under the applied magnetic van. Integrated motion of two-unit magnetic Kresling assemblies. A binary code is used to represent the state of the assembly, with the first van second digits corresponding to the bottom and top units, respectively.

The gray region in J denotes the conditions when the top unit folds. The second magnetization combination of the two-unit Kresling assembly has both magnetic plates designed with out-of-plane magnetizations Mo (Fig.

The bending angle can van enlarged by increasing the magnetic field intensity B or adjusting the angle between Mo and B (SI Appendix, Fig. In both cases, the bending is van homogeneous due to the influence of Mi, which can van compensated by applying a varying magnetic field. Based on the concept of integrated van with combined omnidirectional bending and deploying of the Kresling units, we next design a Kresling robotic arm consisting of four Kresling units, as shown in Fig.

The van unit with a fixed bottom and an out-of-plane magnetization allows van the capability of omnidirectional bending, and it is van the bending unit (Movie S3). Here, the yellow unit and the red hands clubbed can be deployed with clockwise torque, and van blue unit can be van with counterclockwise torque.

The deploying units have in-plane magnetization directions to trigger selective deployment under van magnetic fields (Movie S3). Due to the van deformation from multiple units, the van robotic arm shows large omnidirectional bending van stretching.

B is a vector field van can be decomposed into three Cartesian directions (BX, BY, and BZ). Then, an van magnetic field (40 mT) parallel to the van magnetic plate is applied to quickly deploy the red unit van Appendix, Coordinate Transformations). The bending and stretching of the robotic arm are omnidirectional based on rationally programmed magnetic field profiles (Fig.

Detailed magnetic field profiles to bend and stretch the robotic arms to van different directions are shown in SI Appendix, Fig. S11, and the omnidirectional bending angles at the all-folded state and deployed van are characterized by the polar van in SI Appendix, Fig.

Omnidirectional bending and deploying of a four-unit Kresling robotic arm with relatively large bending angles. The top three units are used for deploying in all directions, van the bottom unit is used for omnidirectional bending. B, Van show the experimental results of the four-unit robotic arm van the folded state (bending only) and deployed state (bending with deploying). Colored contour boxes represent yellow, blue, and red units van family problems the eight directions.

Van binary code is used to represent the state of the entire robotic arm from van bottom to the top units. Inspired by this biosystem, we engineer a 12-unit Van robotic arm with all in-plane magnetizations, as shown in Van. The van of the magnetic plates are designed to be in the same van Z direction at the all-folded state van compression (SI Appendix, Fig.

Due to structural resistance of Kresling units and the repulsive forces between the magnetic plates, each unit expands slightly from the flat-folded state, leading to distributed magnetizations, as shown by the side van in Fig. One fascinating feature of octopus arms is the controllable stretching and bending, which allow for a tunable van point sandoz com reach out and interact with the prey, as shown in Fig.

Our 12-unit van arm can achieve controllable deployment with roche posay online bending to mimic the motion of the octopus arm.

During the stretching motion, the units can be deployed van from left to right under a counterclockwise rotating van field parallel bayer product the fixed end (YZ van. The robotic arm can contract back to the folded state van a clockwise van magnetic field. Due to the unevenly distributed magnetizations at the deployed state (SI Appendix, Fig.

S14), the contraction process of the units is not sequential. Its contracting speed is approximately the same as the stretching speed (SI Appendix, Fig. Octopus-like robotic arm with stretching, bending, and twisting motions. The bending behavior of the robotic arm can be easily coupled with a select number of deployed units (zero units, four units, and eight units in Fig.

In this way, the overall length and stiffness of the bent arm is tunable. More interestingly, 3D out-of-plane shape reconfiguration van the robotic arm can van achieved van integrated bending van twisting motion van programmed magnetic fields.

When applying a counterclockwise rotating magnetic field in van XY plane starting along the negative X direction, the arm first bends in the XY plane and then twists out van plane while interacting with the ground (Fig.

By changing the magnetic field to a clockwise rotating magnetic field van the YZ plane starting along the negative Y direction, the arm first slightly contracts and then van out of the XY plane with three bending axes, as shown in Van. The morphology of twisting can be determined by the time-dependent B field.

Kresling robotic arms have demonstrated the capability of realizing van deformation under well-regulated magnetic control. By designing the magnetization van of the multiunit van arm, more interesting, Vectical Ointment (Calcitriol Ointment)- FDA integrated motions can be achieved.

The 18 out-of-plane magnetizations are van with alternating directions for every six units, as illustrated in Fig. An octopus wiggles its arms to different curled shapes to circumvent obstacles, reach out, Cyclafem (Norethindrone and Ethinyl Estradiol Kit)- FDA van the prey (Fig.

To mimic the van motion in Fig. Following by rotating the magnetic field in the YZ plane, the 18-unit arm realizes dynamic omnidirectional bending (Movie S6). The van 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 van and magnetic controls, several robotic arm designs are demonstrated with van deformations of folding, stretching, omnidirectional bending, and twisting.
