  1. In the main text, we have one expression that the SEMR TL can run at a speed of 630 mm/s or 70 BL/s which is incorrect. It should be 315 mm/s and 35 BL/s. This will not affect our conclusion.
  2. In supplementary table 1, the maximum speed for SEMR TST and TL are not corrected, which should be 630 mm/s and 320 mm/s, respectively.
  3. In the Methods section, the mass ratio of Eco-flex 30 to PDMS is 10:1.
