Mechanics of the formation of a channel by a head of a bending body is considered. Equations are derived of the motion of the body in the channel with its simultaneous formation, which contain the positive feedback. Control is described of various modes of motion and also the transition from one mode to another, including the transition to the motion on account of the feedback. The clarified interrelation of the pressure of the body, its speed, and the responses of the fluid makes it possible to describe the mechanics of the formation and deformation of the channel, which denies the possibility of motion of the body on account of the positive feedback.
