Problems solved by technology

[0005] The present invention solves the problem that the design of the body mechanism of the frog-like swimming robot in the prior art is mainly based on rigid materials, and its bearing capacity and motion precision are high, the structure is complex, the volume and weight are relatively large, and it is difficult to realize the lightweight and small size of the machine. The propulsion process is subject to greater resistance, which reduces the mobility of the robot during operation, and the sealing is not good, and the problem of water penetration is prone to occur. A frog-like swimming robot driven by joint-type pneumatic software actuators is provided.

Abstract

The invention provides a frog imitating swimming robot based on driving of a joint type aerodynamic soft body actuator, relates to a frog imitating swimming robot, and belongs to the field of robots.The frog imitating swimming robot solves the problems that in the prior art, the design of a body mechanism of a frog imitating swimming robot mainly uses a rigid material as the main material, the bearing capacity and movement precision are high, but the structure is complex, the size and the weight are too large, lightweight and miniaturization of a machine are difficult to realize, the appliedresistance in the propulsion process is large, the maneuverability of the robot in the running process is reduced, sealing performance is poor, and the water permeability phenomenon easily occurs. Thefrog imitating swimming robot comprises a robot main trunk, a robot left forelimb, a robot right forelimb, a robot left hind limb, a robot right hind limb, an aerodynamic system and an electric control system. The robot main trunk comprises a streamline upper shell, a lower shell and a plurality of main body trunk clamping buckles; and the aerodynamic system communicates with the robot left forelimb, the robot right forelimb, the robot left hind limb and the robot right hind limb.

Description

technical field [0001] The invention relates to a frog-imitating swimming robot, in particular to a frog-imitating swimming robot driven by a joint-type pneumatic soft actuator, which belongs to the field of robots. [0002] The invention relates to the field of bionic robots, especially the field of bionic swimming robots that move in a sliding propulsion mode. By using rigid, soft and soft materials, and adopting 3D printing, molding and bonding processing technologies, the body mechanism integrates rigid, flexible and soft materials. 1. The common characteristics of soft materials, that is, while ensuring sufficient carrying capacity and toughness, reducing the weight of the robot body, and enhancing the environmental adaptability of the robot, it makes the robot body structure more compact. Moreover, the streamlined shape of the main trunk and the one-way water pushing characteristic of the hindlimb flippers help reduce the movement resistance of the robot and improve the ...
