Gastropods crawl on complex surfaces using pedal waves, inspiring potential solutions for navigating rough, narrow, and steep terrains. The most common method for pedal wave actuation involves discrete traveling waves, which use finite states to mimic continuous movement. This work presents a bionic gastropod robot that employs continuous wave actuation, accompanied by a comprehensive theoretical analysis. An elastic model is proposed, integrating both strain potential and gravitational potential. This model is thoroughly explained and can be used for control purposes, offering an alternative to the black box approach. Additionally, a controller based on Central Pattern Generators (CPG) using the Hopf oscillator was designed. Experimental results demonstrated that the theoretical curves calculated from the elastic model accurately describe the shape of gastropod waves under both small and large bending deformations. The bidirectional driving of the gastropod waves was successfully achieved by the designed controller. Copyright held by the owner/author(s). Publication rights licensed to ACM.
