System and method for producing made-to-order designs on the surface of an extraterrestrial body

A device for producing made-to-order designs on a surface of an extraterrestrial body, the device comprising:

• a surface altering tool configured to rearrange material on the surface;
• a motorized vehicle capable of traversing the surface of the extraterrestrial body, the vehicle supporting the surface altering tool;
• an imaging device supported on the vehicle, the imaging device being configured for capturing an image of the surface;
• a communication system for receiving a control signal transmitted from Earth, and for transmitting an image signal to Earth;
• and
• a control module configured to control operation at least one of the vehicle and the surface altering tool to produce a design in accordance with the control signal.

A system for producing made-to-order designs on a surface of a planetary body, the system comprising:

• a communication system for transmitting a control signal to a device on the body;
• and
• a computer-implemented system comprising:
• a request module for receiving a request to create a design on the surface;
• a command module for preparing the control signal causing the device to create the design;
• and
• an imaging module for receiving from the device an image signal providing an image of the design created on the surface.

A configurable-tread wheel, the configurable-tread wheel comprising:

• a wheel hub defining a plurality of radially-extending channels;
• a plurality of tread elements, each tread element being supported in a respective one of said plurality of radially-extending channels, each tread element comprising:
• a tread head supported on an elongated post;
• a rotating cup having a central opening for receiving said post, a radially-extending flange and a plurality of longitudinally-extending ridges spaced about its periphery, said rotating cup terminating in a pin;
• a spring supported about said post and abutting said flange to bias said tread head toward a retracted position;
• an elongated push pin having a central opening for receiving said pin of said rotating cup;
• and
• a grooved insert having an internal channel admitting passage of said elongated push pin and a plurality of longitudinally-extending grooves spaced about its channel, the grooved insert further comprising a plurality of angled surfaces configured to guide the ridges of the rotating cup and cause incremental rotation of the rotating cup about an axis in response to reciprocation of the rotating cup within the grooved insert along the axis;
• and
• a plurality of solenoids supported within said wheel hub, each of said plurality of solenoids being operatively connected to said control module to permit actuation of each said solenoid upon receipt of a control signal from said control module.
