The invention discloses light-weight and small-sized mangneto swinging bionic
robot fish, which comprises a fish body, a magnetic motive force fish
tail, a U-shaped block and a charging
pile, wherein the fish body and the magnetic motive force fish
tail are connected through the U-shaped block, the charging
pile is arranged at the lower end of the surface, connected with the fish
tail, of the fish body, the fish body comprises an
infrared sensing probe, a second waterproof casing I, a second waterproof casing II, a
control switch and a waterproof soft plug, the second waterproof casing II is arranged at the outer surface of the fish body, and the magnetic motive force fish tail comprises an magnetic
induction coil, a rotating shaft, a PVC (
polyvinyl chloride) tube
pipe, a round permanent
magnet and a flexible fish tail. The light-weight and small-sized mangneto swinging bionic
robot fish has the advantages that the structure is simple, the weight is light, and the size is small; a magnetic motive force pushing mechanism does not need any waterproof protection, and the complexity of the mechanism is greatly reduced, the
energy consumption is low, and the cruising capability is improved; the
energy consumption power of a magnetic motive force mode is 1 / 4 of that of a motor, and in addition, the work
voltage range is wider; the control is simple and convenient, and the advancing, the acceleration, the turning, the sinking and floating and the like of the
robot fish can be easily controlled through controlling the current direction and the current intensity of the coil.
