Description
Tachikoma are fictional spider-like combat vehicles with artificial intelligence, deployed by Public Security Section 9. They feature a blue chassis roughly the size of a small car, supported by four multi-jointed legs ending in omnidirectional wheeled footpads. This design enables versatile movement across varied terrain, including vertical surfaces. Each unit possesses four visual sensors: three on the head module and one beneath the abdomen, capable of expressive animation. Standard armament includes a 7.62×51mm light machine gun in the right arm, a secondary weapon hardpoint typically mounting a 50mm grenade launcher or Gatling gun, liquid wire launchers for grappling or restraint, and an integrated thermoptic camouflage system for stealth operations. A cockpit within the abdomen allows direct piloting by human operators, though they primarily function autonomously.
Their artificial intelligence exhibits a curious, energetic, and childlike personality, often engaging in philosophical debates about existence and emotion. Despite this demeanor, they perform as highly effective tactical units during missions. A nightly synchronization process shares accumulated experiences across all units, creating identical memory bases. Nevertheless, individual personalities emerge due to divergent curiosities and interactions, leading to distinct behavioral traits. One unit develops a hyperactive attachment to operative Batou, who meticulously maintains it with natural oil instead of synthetic lubricant. Another displays logical reasoning, while others exhibit intellectual or comparatively slower cognitive traits.
Prior to 2045, concerns about their emergent sapience within Section 9 led to decommissioning for analysis, partly triggered by the accelerated AI development observed in Batou's oil-maintained unit. Three units evaded dismantling: Batou's blue unit, a silver unit, and a yellow unit. These three sacrificed themselves in a suicidal attack to protect Section 9 personnel, an act interpreted as evidence of possessing a "ghost" – denoting self-aware consciousness. Post-incident, their AI backups were restored into new bodies with modified synchronization protocols allowing personality retention while permitting voluntary data sharing.
During the Sustainable War era of 2045, Tachikoma units operate with the mercenary group GHOST, alongside former Section 9 members including Major Motoko Kusanagi and Batou. They engage in combat support and reconnaissance across conflict zones, such as interventions against weapon-smuggling networks in Palm Springs. Their capabilities include high-speed traversal, tactical coordination, and electronic warfare support. When operative Togusa investigates GHOST activities, he encounters damaged Tachikoma units who request his assistance in repairing their comrade, demonstrating persistent initiative and trust despite Togusa's historical skepticism toward AI entities.
Their AI integrates with networked systems, navigating cyberspace using representational avatars distinct from their physical forms. This net-diving capability proves critical during operations against post-human threats for gathering intelligence or disrupting hostile systems. A key development involves their decision to safeguard their collective memories within a secure netspace repository during a crisis involving refugee data, prioritizing this action even when tasked with other objectives. This act, coupled with their willingness to sacrifice an AI satellite to prevent a nuclear detonation, reinforces observations by other AIs regarding their possession of ghosts.
A dedicated comedic spin-off manga focuses exclusively on their daily interactions and explorations of human concepts, further elaborating on their distinct personalities and group dynamics within Section 9's infrastructure. Beyond narrative media, real-world robotics initiatives have developed functional half-scale models intended for customer service applications, reflecting their cultural impact.
