FABRICATING LIGHTWEIGHT SKIN SYSTEMS FOR LARGE SCALE ROBOTIC CHARACTERS

摘要

A method of fabricating a skin system or its elements using a laser cutter. The laser cutter is controlled to perform multiple passes to selectively cut away layers of material on a surface of a sheet of cellular foam materials. Each layer of material to be removed is defined by a cut or texture pattern. The laser cutter is operated to cut deeper with each layer of material removed by setting a different resolution for the laser cutter for each layer. For example, a laser cutter may be selectively controlled to operate within a resolution range, and each layer defined by the same or different cut pattern is cut using a different resolution. The method includes associating lower resolution settings for the first or outer layers to remove a first depth of material from the skin sheet's surface and associating higher and higher resolution settings for additional layers.

1. A method of texturing cellular foam material, comprising:
providing a sheet of cellular foam material as input to a laser cutter; first controlling the laser cutter to make a first pass over a surface of the sheet cutting a first layer of a texture pattern; and second controlling the laser cutter to make a second pass over the surface of the sheet cutting a second layer of the texture pattern, wherein the laser cutter has a first resolution setting during the first controlling and a second resolution setting during the second controlling that is greater than the first resolution setting.
