Abstract
A short range peer-to-peer communications system includes a first perception sensor and a first peer-to-peer communications system on a first machine and a second perception sensor and a second peer-to-peer communications system on a second machine. A first controller generates a first electronic map of a first perceived work environment associated with the first machine and transmits first data associated with first electronic map to the second machine through the first peer-to-peer communications system. A second controller generates a second electronic map of the second perceived work environment associated with the second machine based upon the plurality of second raw data points, receives the first data from the first machine through the second peer-to-peer communications system, and supplements the second electronic map based upon the first data.
