Geometrid moth (Geometridae) "inchworm" caterpillar

Geometridae is a very large family of moths whose larvae are commonly known as inchworms or loopers. The inchworm's simple and effective design provided inspiration for the ESA Discovery activity 'Soft Annelid-Inspired Robot with Peristaltic Gait using Low Voltage Fault-Tolerant Artificial Muscles for Planetary Exploration', in which researchers from the University of Gothenburg explored a new approach to soft robot locomotion.
