OG-9 homing spider droid/Legends

The OG-9 homing spider droid, sometimes referred to as the spider walker, was a droid walker manufactured for anti-vehicular combat by the Commerce Guild before and after the Clone Wars.

Details
Like the other combat automata deployed by the Commerce Guild, the homing spider droids were originally developed to enforce the Guild's laws and to ensure that its customers paid their debts.

Like the Republic's SPHA walkers, it was effective against both ground-based and airborne targets and was designed to transport a large and devastating weapon throughout the battlefield. The homing droid's round, armoured body contained a volatile reactor. If the core was breached, the reactor violently exploded.



The homing spider could cover wide areas of the battlefield with its four all-terrain legs. Because of its great height and extendable hydraulics, the walker could position its homing laser above enemy targets or move to higher ground to blast at air vehicles. However, the legs were vulnerable to damage, and if just one hydraulic leg was disabled, the entire vehicle would crash to the ground. Despite its weaknesses, the homing spider could walk along the bottom of seabeds, fully submerged in water, as well as scale steep cliffs.

The spider walker's chief weapon was a laser emplacement mounted above the droid's round body. This circular dish fired a precision homing laser that could be maintained until the drone's internal power supply was finished. This sustained firepower allowed the homing spider to weaken shields, destroy armoured vehicles and bombard troop formations. An antipersonnel cannon beneath the walker's round body could be used for close-quarters combat, while a retractable ion cannon could be added to disable starships or other powerful vehicles. There were also weapon mounts that allowed other armaments to be fixed to the droid. Sensor equipment fitted into the homing spider, enabled it to target and keep track of moving enemy targets.

Homing spider droids were distinguished by a number code alone and did not have developed personalities of long-term memory modules. Instead, they possessed an internal logic processor and military protocols for long-ranged missions, but the droids were often programmed to receive orders directly from a central control computer.

History
The homing spider droid was developed by Baktoid Armor Workshop prior to its dissolution by the Trade Federation not long after the Battle of Naboo. During Baktoid's final days, the company tried to sell many of its designs, and the Commerce Guild purchased several droid models including the spider walker.

The homing spider droid first appeared during the Battle of Geonosis where they fought against the Grand Army of the Republic. They were later deployed during the Clone Wars by the combined forces of the Confederacy of Independent Systems. A number of droids were used in the defence of the Commerce Guild homeworld of Felucia.

Following the execution of the Separatist Council by Darth Sidious's new apprentice, Darth Vader, these units were de-activated.
