EVE

EVE (Extraterrestrial Vegetation Evaluator) is an advanced probe droid. Called "Probe One" by the Captain of the Axiom, EVE is one of several robots who are sent to Earth on a scanning mission. An advanced model equipped with a quasar ion cannon and capable of flight and high speeds, she is determined to complete her task and initially fails to notice her would-be robot Romeo, WALL•E. The two robots subsequently bond, however, and the more she sees how much WALL•E cares for her, the more she falls for him, eventually making it her top priority to protect him.

Capabilities
EVE has all necessary parts of a probe droid. She has an ergonomic suitable shape, scanner, flight at high speeds to cross ground quickly and morphable fingers for different purposes. However, it is odd that a simple probe would have a laser gun. The gun might have been installed to remove obstacles. An example of this is when she blasts away an electromagnet she is trapped by.
