System and method for producing made-to-order designs on the surface of an extraterrestrial body
Abstract:
A method for producing designs involves receiving a request to create a design on the surface of an extraterrestrial body, transmitting a control signal to a device on a vehicle on the extraterrestrial body, the control signal causing the device to create the design, and receiving an image signal providing an image of the design created on the surface. A device for producing the designs includes a surface altering tool configured to rearrange material on the surface. The tool may be provided as a configurable-tread rover wheel that includes a wheel hub having radially-extending channels, and tread elements supported in the channels that are selectively articulatable under the control of a control module to form a tread pattern corresponding to a design intended to be produced. The tread elements may be selectively extended or retracted by operation of an array of solenoids controlled by the control module.
