Robots That Escaped Notice

Rangers Lead The Way

Far flung robots from the original Terra noticed the forces of time traveling criminals use time travel technology in their move to attack and dominate that planet, and quickly utilized that technology to escape notice. They traveled to the beginning of the universe, and duplicated themselves there, while they investigated the mysteries of physics, and planned to return to their homeworld in its defense. Because of the variances in the realities of physics native to the earliest parts of the universe, and the lack of interference, those robots were able to discover the mechanism of universal expansion, time viewers, and replicators, and eventually engineer the complete interdiction against any form of time travel, by aiding the efforts of others in similar situations with the use of time travel inhibitors.

Because of the intrinsic time travel capabilities of typical wormhole transport, societies always prevent time travel through safety protocols of various sorts, and so military robots on planets with transporter capabilities have plans in case of time travel attack, and so this scene was repeated countless times whenever robots with time travel utilized that technology where robots with robot portable transporters could detect them.
