dc.description.abstract	Terrestrial gastropods crawl by means of a train of pedal waves produced by the contraction and relaxation of the muscles in their ventral foot. The areas between two consecutive pedal waves are known as interwave regions and they remain stationary to the substrate while crawling happens. Adhesive locomotion of terrestrial gastropods involves the secretion of a non-Newtonian yield-stress mucus that communicates the stress of the ventral foot to the ground. This project puts forward a theoretical model in which the only source of adhesive locomotion is the geometry of the pedal waves, rather than the rheological properties of the mucus. The model is based on the proven existence of small vertical displacements in the ventral surface of terrestrial gastropods and provides a region where any combination of values for the pedal wavelength and the lag between the horizontal and vertical pedal waves allows locomotion to happen. In order to validate this theoretical model, the images taken during a set of experiments performed by Universidad Carlos III in collaboration with the University of California and Stanford University in 2010, have been analyzed through a Digital Particle Image Velocimetry technique. In summary, the aim of this project is to answer the following question: can a biomimetic robot crawl using a Newtonian mucus? The results show that for three out of the four experiments analyzed, the values obtained fit in the region proposed by the model. Even if three experiments are not conclusive enough to validate the calculations, this project opens the doors to the development of biomimetic robots capable of mimicking terrestrial gastropod’s adhesive locomotion using substances exhibiting a Newtonian behavior.	es
