"An aerobot is
an aerial robot,
usually used in the context of an uncrewed
space probe or unmanned
aerial vehicle.
While work has been done since the 1960s on robot "rovers"
to explore the Moon and
other worlds in the Solar
System,
such machines have limitations. They tend to be expensive and have
limited range, and due to the communications time lags over
interplanetary distances, they have to be smart enough to navigate
without disabling themselves. For planets with atmospheres of any
substance, however, there is an alternative: an autonomous flying
robot, or "aerobot". Most
aerobot concepts are based on aerostats,
primarily balloons,
but occasionally airships.
Flying above obstructions in the winds, a balloon could explore
large regions of a planet in detail for relatively low cost.
Airplanes for planetary exploration have also been proposed."
