Single Trooper Aerial Platform
From ImperialWiki
STAP deployed in the Naboo invasion
Droid-specific design
The STAP does not have an enclosed cockpit, and exhaust from the vehicle's engines blows directly on the legs of the pilot. While these features were not problems for the Trade Federation's battle droids, a living humanoid pilot trying to operate a STAP could be blinded by wind and quickly suffer severe leg burns.
