Elongated anguilliform swimmers, like eels, demonstrate exceptional swimming efficiency during their migration period, travelling thousands of kilometres without feeding. To explore and decompose this type of swimming, 1-guilla, the anguilliform, eel-like robot was designed. The basic ingredient for 1-guilla to move forward is to create a wave that travels down its body; a travelling wave. How can 1-guilla use the travelling wave to swim fast? How can 1-guilla spend minimum energy to travel far? Through an exchange with waves, colors and different travelling wave motions, 1-guilla in this video manages to find some answers to those questions.
