The Spy Bots.
The Spy Bots were also invented by Nikola Tesla
The Spy Bots are drones (flying robots), the drones float on a force field created by (Tesla's) Anti-Gravity field generator.
For propulsion the Spy Bots are equiped with a little inertial drive engine.
This particular method of propulsion makes the Spy Bots behave in a jerky way like water-fleas.
The Spy Bots are not armed, if necessary they communicate with the Trinity Drones for assistance.
(Please note: The eyes of the Spy Bots are bio-engineered and similar to the eyes used in the Google glass, later I will devote a separate page to the Google glass.)
