Robot design and actuation principles.

Caption

(A) Bioinspiration from natural jellyfish and multifunctional capabilities of the jellyfish-inspired magnetic soft robot (J-MSR) platform. (B) Comparison of the speed and the density between our J-MSRs and other jellyfish-inspired robots reported in the literature. The proposed J-MSR achieved a maximum speed of 14.85 BL/s (body lengths per second) while exhibiting a marked density difference with the liquid environment. (C) Biomedical applications of the J-MSRs. (D) Schematic illustration of the J-MSR’s swimming process under the actuation of the asymmetric trapezoidal magnetic field waveform. (E) Schematic of the asymmetric trapezoidal magnetic field waveform, highlighting key variables including the maximum positive magnetic flux density B1, the maximum negative magnetic flux density B2, the duration of the preload phase T1, the duration of the contraction phase T2, the duration of the glide phase T3, and the duration of the recovery phase T4.
