RESEARCHFUL DEVELOPMENT OF UNDERWATER ROBOFISH II——DEVELOPMENT OF A SMALL EXPERIMENTAL ROBOFISH

This paper introduced a small experimental robofish as an experimental flat for a study of the hydrodynamics capability of robofish, which have a rigid head and flexible body of 5 DOF and lunate caudal fin. The length of the robofish is 890mm, maximal velocity is 20cm/s, maximal turning rate is 120°/s, minimal turning radius is 40cm. The experiment of general capacity and C-shape locomotion of the experimental robofish indicated that they have preferable swimming capacity and high maneuverability.
