Abstract

An automation and motion control system for theatrical objects, such as theatrical props, cameras, stunt persons, lighting, scenery, drapery or other similar types of devices or items, is provided to coordinate the movement of the objects on a large scale and/or to control the operation of the objects.

Claims

1. A control system to move an object comprising:

an operator console node enabled to permit an operator to interact with the control system;

a plurality of axis nodes, each axis node of the plurality of axis nodes having a microprocessor and being associated with an item of equipment used to move an object in a predefined space; and

a space device, the space device comprising

a display device enabled to display movement of the object in the predefined space;

a first operator interface enabled to permit an operator to define a movement path for the object in the predefined space, the movement path adjusts both the position of the object and the orientation of the object; and

a second operator interface enabled to permit an operator to define the relationship between the object and a plurality of engines used to move the object, each engine of the plurality of engines corresponding to an axis node of the plurality of axis nodes;

the space device providing the defined movement path for the object and the relationship between the object and the plurality of engines to at least one axis node the plurality of axis nodes; and

the at least one axis node the plurality of axis nodes processing the defined movement path for the object and the relationship between the object and the plurality of engines to generate one or more control instructions to control operation of the item of equipment to move the object along the defined movement path.

2. The control system of claim 1 wherein the second operator interface is configured to provide at least one lace to connect an engine to a connection point on an object.

3. The control system of claim 2 wherein the at least one axis node generates the one or more control instructions by calculating changes in lengths of laces connecting the object and the plurality of engines.

4. The control system of claim 1 wherein the position of the object is defined relative to a set of axis defined for the predefined space and the orientation of the object is defined relative to a second set of axis defined relative to a single point on the object.

5. The control system of claim 1 wherein the display device displays both simulated movements of the object and actual movement of the objects by the plurality of axis nodes.

6. The control system of claim 1 wherein the at least one axis node processes the defined movement path for the object and the relationship between the object and the plurality of engines to determine possible collision events for the object.
