Thermoplastic Conditioned to Walk (VIDEO) Cell Press This video is under embargo. Please login to access this video.

The LCN-based robot is initially sensitive to heat to allow bending and locomotion only by thermal pulses but is insensitive to light yet becomes light-active after associating the two stimuli.Under temporally modulated irradiation, the 'conditioned' soft robot starts to walk on a surface with asymmetric friction, which is beyond its capabilities before the conditioning process.
