Soft robots have developed gradually in the fields of portability, high precision, and low noise level due to their unique advantages of low noise and low energy consumption. This paper proposes an electromagnetically driven elastomer, using gelatin and glycerol (GG) as matrix materials and a mixture of multiwalled carbon nanotubes (MWCNTs) and Ag NWs (MA) as the conductive medium. Inchworm-inspired and spider-inspired soft robots have been developed, demonstrating fast movement speed, flexibility, and loading performance. The GG/MA elastomer with a 1:1.2 ratio shows a low elastic modulus and easy demolding. With a 1:1 mixing ratio of MWCNT and Ag NWs, the elastomer exhibits excellent conductivity, torsional stability, and fatigue resistance. The inchworm-inspired soft robot achieves an average speed of 3 mm/s, while supporting weights of grains and capsule at 2.5 and 2.3 mm/s, respectively. The spider-inspired soft robot demonstrates a maximum carrying capacity of 22 g, showcasing its load-bearing capabilities. Overall, the GG/MA elastomer-based soft robot exhibits exceptional flexibility, adaptability, and reliability, with potential in various fields such as goods transportation, safety monitoring, and disaster relief.
