Cybernetics

Cybernetics is the interdisciplinary study of the structure of regulatory systems. The field involves the replacement and/or improvement of an organism's organic components with robotic ones.

The technology is used by both terrans and protoss.

Protoss Cybernetics
The protoss are a technologically advanced race and their use of cybernetics is testament to this. In their time of operation, dragoon 'pilots' could come to control their exoskeleton as well as if it were their own body. This is an ability shared by the current generation of protoss cybernetic warriors, the immortals and stalkers.

Protoss cybernetics extends beyond crippled warriors. Zealot power suits are compatible with cybernetic leg enhancements that bolster the warrior's speed.

Terran Cybernetics
The study and practice of cybernetics was an issue of great controversy to humanity in the 21st and 22nd centuries. As cybernetics became more commonplace, humanist factions lashed out, resulting in numerous acts of terrorism between the humanist and corporate factions. With the formation of the United Powers League however, it was argued that cyber technology, among other things, led to the degeneration of the human species. As such, Earth's cybernetics were rounded up in Project Purification, either executed or sent to the colonization mission to Gantris VI that instead landed the colonists in the Koprulu Sector.

Of the inhabitants of the Koprulu Sector, cyber technology is reasonably sophisticated. Examples include occular implants and cybernetic grafts that essentially perform as advanced prosthetics. In addition, remnants of the Terran Confederacy undertook research into dragoon technology, hoping to convert it so that it could be used for human reconstruction. However, the information was stolen by the Kimeran Pirates and sold on the black market.
