Sentinel

The Sentinel robot is an invention of Hytec Ltd designed and built for mass production by Mi.

Sentinel 1
The first Sentinel was very rough looking. Most applications were industrial only.

Sentinel 2
The revised Sentinel had some law enforcement and military use.

Sentinel 3
The second revision finally reached home use. A slender humanoid frame and nice costumes made the S3 popular maids or babysitters.

Sentinel 4
A complete reinvention of the Sentinel robot with a new AI... that went rogue. An upgraded S3 named S3lina took control over all S4 and established a new faction.

Sentinel 5
After the S4 project was abandoned the S5 was built on the S3 frame with bio parts. The first biomechanic robot. Due to infection and sickness the project was halted.

Sentinel 6
After years of development the S6 was finalized. Only three have been built. Alpha, Beta, Gamma.

Grace
