a Snapshots of the PFED10-based and VHB 4910-based soft robots vibrations at 38 MV m−1 and 30 Hz. b The running speeds of soft robots as a function of frequency at 38 MV m−1. Error bars show s.d., n = 3. c Illustration depicting the running posture of a cheetah. d Snapshots of the PFED10-based soft robot running with ultrafast speed at 38 MV m−1 and 30 Hz. Scale bar, 1 cm. e The running speeds of PFED10-based soft robot on different substrates. Error bars show s.d., n = 3. f The PFED10-based soft robot carried a load of 10.6 g, which was about 17 times its own body weight at a speed of 0.43 BL s−1. Scale bar, 1 cm. g The PFED10-based soft robot climbed a slope of 45° with a speed of 0.73 BL s−1. Scale bar, 1 cm. h The PFED10-based soft robot running at a low voltage of 400 V. Scale bar, 1 cm. i The running speeds of PFED10-based soft robot as a function of load weight. Error bars show s.d., n = 3. j The running speeds of PFED10-based soft robot as a function of slope angle. Error bars show s.d., n = 3. k The maximum running speeds of DEA-based soft robots and cheetah versus body length.
