M.A.J. Mailbot

The M.A.J. Mailbot is a model of robot developed for and chiefly utilized by the Galactic Postal Service to deliver physical mail and parcels, but are sometimes employed by private owners and services, as well.

Development
Invented in late 1786 by inventor Kadorfus Stromboli, the Mailbot was implimented experimentally by the GPS as early as May 1787. However, the original Mailbot often took multiple years to deliver packages, and the GPS research team began looking for a quicker alternative.

Their alternative arrived in 1833 with the invention of the Relativity Drive, and later became practically implemented in the M.A.J. Mailbot in 1840, when these drives became commonly available.

Today, due to the standardized size of the modern M.A.J. Mailbot, in conjunction with the addition of the Relativity Drive, letters and packages will arrive within the week, or, at longer distances, within the month.
