The Probe is the most basic of the protoss units. Probes warp in all Protoss buildings. Once a Probe begins the warp in process, it can leave and do other things and the building will warp in on its own.
The tiny Probe was designed by the Khalai to lay the foundation for Protoss colonies on hostile worlds where living workers would be at too great a risk. They also produce and plant the warp-beacons that allow them to teleport buildings from Aiur to distant planets.
Particle Beam (SC1)
The Probe's StarCraft 2 model
is back in the same role in StarCraft 2. It is the Protoss basic worker unit, and can still harvest minerals, gas, and warp in buildings. Resource gathering has changed somewhat, with improved AI and lower quantities gathered per trip.
