Adaptive serpentine locomotion of a snake robot involuntarily activated and modified through sensory feedback affected by longitudinal frictional anisotropy

Adaptive serpentine locomotion of a snake robot involuntarily activated and modified through sensory feedback affected by longitudinal frictional anisotropy

We aim to develop a snake robot that can autonomously slither over terrains with different surface friction, as found in outdoor environments. We build a simple snake robot with a scaled-up ventral scale plate under each segment, based on the property of longitudinal fricti onal anisotropy of a real...
