This paper is concerned with the motion of an aquatic robot whose body has the form of a
sharp-edged foil. The robot is propelled by rotating the internal rotor without shell …

Locomotion of multibody systems in resistive media can be based on periodic change of the
system configuration. The following types of mobile robotic systems are examined in the …

This paper addresses the problem of a rigid body moving on a plane (a platform) whose
motion is initiated by oscillations of a point mass relative to the body in the presence of the …

1. The model of an ideal fluid. The simplest and the most widely studied mathematical model
describing the motion of a rigid body in an ideal fluid is provided by the Kirchhoff equations …

This paper is concerned with the motion of a helical body in an ideal fluid, which is
controlled by rotating three internal rotors. It is proved that the motion of the body is always …

In this chapter, we consider rectilinear motions of mobile systems that move in resistive
media without external propelling devices (legs, wheels, caterpillars, fins, screw propellers …

A rigid body $\mathcal {B} $ moves in an otherwise quiescent viscous liquid filling the whole
space outside $\mathcal {B} $, under the action of a time-periodic force $\boldsymbol …

The motion of a circular cylinder in a fluid in the presence of circulation and external periodic
force and torque is studied. It is shown that for a suitable choice of the frequency of external …

The article presents the screwless overwater fish-like mobile robot, driven by an internal
rotating rotor. The robot has a rigid case which doesn't be transform while moving …

This paper considers the plane-parallel motion of an elliptic foil in a fluid with a nonzero
constant circulation under the action of external periodic forces and torque. The existence of …
