Mechanical/Robotic Items perform automated and repetitious functions to accomplish a task. In sufficiently advanced cultures, clothing, weapons, and armor can be integrated with “wearable technology” to camouflage or enhance Computer tech and items, Cybernetic tech and items, Robotic tech and items, and/or Nano tech and items.
Robotic Items typically involve sensors and are controlled with a greater range of parameters via a computer.
Mechanical Items are usually just rudimentary robotics, and have more specific parameters and have few sensors or integrated parameters with other machines or robots.
