Droid sensorscope

A droid sensorscope, also simply known as a periscope, was a device standard on R-series astromech droids, equipped with a full-spectrum transceiver with electro-photo receptors, dedicated energy receptors, heat detector, and motion detectors. Data received through the sensorscope was routed to the droid's Intellex IV internal computer. It was an extendible auxiliary visual imaging system that raised up from a panel in the droid's dome, allowing it to see what shorter droids usually couldn't.

R2-D2 used his sensorscope at various times including to navigate through a swamp on Dagobah after falling into the water shortly after the Battle of Hoth. He later used it to see after falling into the sands of Tatooine to escape Jabba the Hutt's sail barge during the Rescue of Han Solo.
