In the grand annals of military-funded robotics experiments, OCTOR may not have quite the same level of cred as, say, Crusher, but that doesn't mean the bot isn't useful. The current version consists of one long tentacle that, like an elephant's trunk, can be used to pick up and manipulate objects. The tentacle is powered by compressed air, and uses a range of sensors and cameras to move in three dimensions and relay info back to base. Potential applications being touted by the bot's developers include reconnaissance and bomb disposal, but they can't fool us. We've seen "Spiderman 2," and we know what those tentacles are really for.
