The Probe droid is another droid model from Arakyd Industries. Commonly referred to as the Viper probe droid or probot, it is an efficient deep space exploration and reconnaissance droid. The probe droid was heavily designed by Viper Sensor Intelligence Systems, a corporation that was acquired by Arakyd during the Clone Wars. This is where the more common name Viper Probe Droid comes from.

Probe droids started out as survey and exploration-focused droids. With the fall of the Galactic Republic and the current civil war, Arakyd modified the droids and added military-grade sensors and equipment. Now they are almost exclusively used by the military, with some science and exploration groups having a few units themselves. Their custom single-use hyperspace pod allows them to be delivered to their targets from across the galaxy.

The design of the Probe droid is an example of superior engineering. They measure 1.6 meters in height when their arms are extended. The main component of the design is a central pod with five arms that extend downward or can be folded up to fit in the custom pod for deployment. There are also several sensor arms that remain stored around the side of the main component. These retractable arms are for gathering samples of whatever the programming requires. On top of the main component is a domed head. This contains an integrated flood light as well as high-resolution sensors and receivers that record and track motion, acoustic, sonic, and seismic activity. These sensors and receivers also include a radiation meter, a magnetic imager, and a holocamera, which can produce a live feed to its receiving terminal. The domed head could rotate 360 degrees on top of the main component. This allowed it to continue to survey an area while at the same time focusing on gathering samples. The probe droid had a built-in repulsorlift generator that allowed it to travel over any terrain. A built-in thruster system also allows the probe droid to maneuver in the vacuum of space.

The probe droid was given a state-of-the-art communication transmission system that allowed it to send data across deep space. The droid could be programmed to send an audio-encrypted computer code that would be decoded when relayed back to a high-frequency HoloNet transceiver. This technology would ensure that the message would reach its intended target without being hacked or deciphered.

Security was of the utmost importance in the programming of the probe droids. Due to their military objectives and data collection, they were built with self-destructive mechanisms. Should the droid become compromised or analyze that it had no escape, it was to terminate itself in order to not allow the collection of its hard drive data. A light blaster was also integrated into the domed head for self-defense or in the case of the hunter-killer models, execution.
