The bionic robotic fish comprises a head, a flexible fish body connected to the head, a controller, an air pressure adjusting module and at least two elastic parts, the flexible fish body is provided with a first containing cavity, the elastic parts are all arranged in the first containing cavity, and the controller is used for controlling the flexible fish body to swing relative to the head; the air pressure adjusting module is electrically connected with the controller and used for adjusting the air pressure of the first containing cavity so as to be switched between a first state and a second state, the air pressure of the first containing cavity in the second state is smaller than that of the first containing cavity in the first state, and the first state is that first friction force exists between the two elastic pieces. In the first state, the minimum distance between the elastic pieces and the inner wall of the first containing cavity is a first interval, in the second state, second friction force exists between the two elastic pieces, the minimum distance between the elastic pieces and the inner wall of the first containing cavity is a second interval, the first interval is larger than the second interval, and the first friction force is smaller than the second friction force. Therefore, the rigidity of the body can be automatically adjusted, and the swimming efficiency of the bionic robotic fish is improved.
本发明公开了一种仿生机器鱼,包括头部和连接于头部的柔性鱼体、控制器、气压调节模块以及至少两个弹性件,柔性鱼体设有第一容置腔,弹性件均设置于第一容置腔内,控制器用于控制柔性鱼体相对头部摆动,气压调节模块电连接控制器并用于调节第一容置腔的气压,以在第一状态与第二状态之间切换,第一容置腔在第二状态下的气压小于在第一状态下的气压,第一状态为两弹性件间具有第一摩擦力,弹性件与第一容置腔内壁的最小距离为第一间距的状态,第二状态为两弹性件间具有第二摩擦力,弹性件与第一容置腔内壁的最小距离为第二间距的状态,第一间距大于第二间距,第一摩擦力小于第二摩擦力。从而能自主调节身体刚度,提高仿生机器鱼的游动效率。
