Sensory feedback should play an important role because motion must be obviously adapted to the environment of the moving organism. This information encompasses the traditional five senses as well as proprioception which is the sense of self-movement or body position.
We aim at addressing the mechanisms providing swimming locomotion driven by proprioception. We suggest that the swimming gaits might be selected by a proprioceptive feedback linking the actual body deformation and the state of the surrounding fluid. By means of a robotic fish we validate our proprioceptive hypothesis to later model the system. We compare our experimental results to our theoretical predictions and we show that the agreement is excellent.
