DESIGN IMPLEMENTATION AND CONTROL OF FISH LIKE ROBOTS

Abstract

Fish robots are widely used in the fields of underwater development, examination and environmental
protection. Usually fish robots have various kinds of components such as accelerometer, depth sensor, magnetic compass,
distance measuring sensor and processor circuits. In this paper we present an approach to design, implementation and
control of fish like robots. All of the circuits, actuators, and processor cards are contained in a typical structure of
25x15x10 cm dimension except of fins and external covers. The swimming experiments are performed in a water tank of
240x120x120 cm where the side walls and the objects make of white board are considered as obstacles. The experiments
results show the successful of fish robots remotely control by passing through differences kind of swimming paths
without hitting obstacles
