Mecha (メカ - me-ka) are giant robots, robot vehicles, robot construction equipment, robot mobile buildings and generally over-sized robot machines. Short for "mechanical", but is unrelated to the tag mechanical. Primarily seen in science fiction settings, though there are several cases of them in fantasy settings.
Power suit - Suit that protects the wearer and/or enhances their abilities, without covering the user entirely.
Power armor - Similar to a power suit, it also covers the pilot entirely in similar fashion to body armor.
Externally piloted mecha - A mecha where the controls are external and the pilot rides on top the machine.
Exoskeleton - Small mecha without a covered cockpit that's worn like a power suit rather than piloted.
Walker - A type of walking mecha that usually lacks arms.
Mecha - Giant (usually anthropomorphic) robots. Can be piloted or not. Some of them even transform into vehicles.
