Robotic marionettes on magnetically-supported and highly mobile puppeteer platforms
First Claim
1. An apparatus for suspending and positioning a show component such as a marionette, comprising:
- a support membrane;
a tender vehicle positioned proximate to a first side of the support membrane, the tender vehicle comprising a drive mechanism selectively positioning the tender vehicle relative to the support membrane; and
a puppeteer vehicle supporting a show component and positioned proximate to a second side of the support membrane opposite the tender vehicle, wherein at least one of the tender vehicle and the puppeteer vehicle comprises one or more rotatable magnetic elements providing a magnetic field maintaining the puppeteer vehicle proximate to the support membrane,wherein the drive mechanism comprises a pair of magnetic wheels each placed with a peripheral edge in contact with the first side of the support membrane and driven to rotate relative to a body of the tender vehicle on one or more axles supported on the body and wherein the puppeteer vehicle comprises a pair of magnetic wheels mounted for free spinning and each positioned with a peripheral edge in contact with the second side of the support membrane opposite the magnetic wheels of the drive mechanism of the tender vehicle, whereby the puppeteer vehicle passively follows the tender vehicle.

Abstract
An apparatus for suspending and positioning marionettes. The apparatus includes a thin, planar support membrane such as a plastic sheet. A tender vehicle is positioned on the upper side of the support membrane. A motor or other drive mechanism selectively positions the tender vehicle relative to the support membrane. The apparatus includes a puppeteer vehicle from which a marionette is suspended. The puppeteer vehicle is positioned proximate to the lower side of the support membrane opposite the tender vehicle. To support the puppeteer vehicle, one or both of the vehicles includes one or more rotatable magnetic elements such that the attractive forces support the weight of the puppeteer vehicle and the marionette. Typically, the puppeteer vehicle is a passive follower, and the drive mechanism of the tender vehicle includes motors to move the magnetic elements and position the tender and following puppeteer vehicle with its marionette to provide a show.

9. A marionette-based show system,
comprising: -
a thin, planar support positioned above a stage; two or more marionette support and positioning assemblies, each of the assemblies comprising; a tender vehicle positioned on an upper surface of the planar membrane with a rotatable magnetic element abutting the upper surface and a drive mechanism moving the tender vehicle on the upper surface in response to control signals; a puppeteer vehicle positioned against a lower surface of the planar support with a rotatable magnetic element abutting the lower surface and magnetically coupled to the magnetic element of the tender vehicle; and a show component supported by the puppeteer vehicle; and a show control system in wireless communication with the tender vehicle to transmit the control signals to selectively position the tender vehicle on the planar support. - View Dependent Claims (10, 11, 12, 13, 14)

15. A marionette support apparatus, comprising:
-
a tender assembly comprising a chassis supporting a pair of motors and a pair of magnetic drive wheels; a puppeteer assembly comprising a chassis supporting a pair of free spinning magnetic wheels, a marionette suspended from the chassis, and a marionette operating mechanism selectively operable to lift at least a portion of the marionette; a support membrane comprising a sheet of flexible and at least translucent material under tension, wherein paired ones of the magnetic wheels of the tender assembly and of the puppeteer assembly abut opposite sides of the support membrane, whereby the puppeteer assembly is suspended by the tender assembly; and a show controller transmitting wireless control signals to the tender assembly to selectively operate each of the motors to position the tender assembly in a plurality of positions on the support membrane, wherein the control signals are transmitted in response determination of a relative position of the tender assembly based on light passing through the support membrane. - View Dependent Claims (16, 17, 18, 19)

20. An apparatus for suspending and positioning objects, comprising:
-
a non-magnetic support membrane; a tender vehicle positioned proximate to a first side of the support membrane, the tender vehicle comprising a drive mechanism selectively positioning the tender vehicle relative to the support membrane; and a vehicle supporting an object and positioned proximate to a second side of the support membrane opposite the tender vehicle, wherein at least one of the tender vehicle and the vehicle comprises one or more rotatable magnetic elements providing a magnetic field maintaining the vehicle proximate to the support membrane, wherein the drive mechanism comprises at least one electric motor rotating the magnetic elements in the tender vehicle and the magnetic elements each comprises a disc-shaped permanent magnet with a peripheral edge abutting the first side of the support membrane such that the peripheral edge rolls upon the first side when the disc-shaped permanent magnet is driven to rotate. - View Dependent Claims (21, 22, 23, 24)
