Sentrobes are enemies from The Legend of Zelda: Skyward Sword. They are security drones built in ancient times and are found in the Lanayru Mining Facility and the Sky Keep. Sentrobes are armed with missiles fired from a central turret and flying bombs fired from their two sides. Link must knock a Sentrobe's missiles back at it in order to defeat it, with the Shield Bash being an effective option. If a Sentrobe fires its bombs, Link must slice them with his sword either vertically or horizontally, in line with the direction of the band of light on the bomb's circumference. Upon its defeat, the device will fall and explode, usually scattering a number of randomly colored Rupees.
