Photo-modulated multi-directional bilayered LCE walker. a Schematic illustration of the fabrication protocol and the moving mechanism of a multi-directional bilayered LCE walker. Photographs showing the multi-directional walker (b) moving either forward or backward upon on-off irradiation of 808/520 nm or 980 nm light, c moving left and then forward upon on-off irradiation of 520 nm and then 808/520 nm light, d moving right and then forward upon on-off irradiation of 808 nm and then 808/520 nm light. e The definition of the starting position coordinate of the LCE walker in x–y plane. The real-time position coordinate of the midpoint A of the LCE walker recorded in f moving forward and backward manner, g moving left and then forward manner, h moving right and then forward manner. Scale bar = 1.0 cm. Source data are provided as a Source Data file
