The driving of the Stewart platform motion is considered as a particular case of the motion of a solid fastened arbitrarily on six rods of variable length. The inertia and weight of the rods are taken into account. The purpose of driving is to obtain the set motion of the platform. Due to obvious instability of such motions, the full range operation of the stand can be provided only by introducing a feedback. It is possible to study the motions of the solid with the arrangement of the rods different from that for the Stewart platform. It is necessary to obtain the set motion of the solid under consideration due to a change in the lengths of the rods. The purpose of driving is to obtain the set motion of the platform. We assume for simplicity that the forces of inertia of the rods are negligible. However, such a method of control is impossible because the initial position of equilibrium is unstable.
