Programming a robot

I want to create a 3d mapping system (in java) that starts out from nothing but an X. The robot will go out from that X and measure things (temperature, location, acceleration, vibrations, time and other measurements). Some of this data (mostly X,Y,Z locations) should begin to create a 3d map. It would be nice if a java object that puts a "dot" on the X,Y,Z coordinates. the java.

The java object should read from a text file that my computer would upload to the web server.
