<p>A movement platform provided with a carrier (2) and at least as three spaced apart clamping means (3), wherein the clamping means each clamp the carrier at a contact point (13) at at least one globular contact surface (14) of the carrier, while at least one clamping means is provided with at least one displacement (4) element for displacing the contact point relative to at least the respective contact surface and/or at least the respective clamping means such that the carrier can rotate about at least two imaginary axes, while the normal forces (Fn) applied by the clamping means to the carrier are in approximately parallel planes, which parallel planes are approximately perpendicular to the tangential plane at the globular surface at the respective contact point.</p> |
