Cezeri is a quadcopter developed by Baykar Unmanned Aerial Vehicle Systems Co. in Turkey. It was named after Ismail al-Jazari (1136–1206), a Muslim polymath: a scholar, inventor, mechanical engineer, artisan and artist from Jazira in Mesopotamia. The 230 kg (510 lb) heavy prototype made the autonomous maiden flight midnight of September 2020,[1] about one year after its introduction to the public at the 2019 Teknofest Istanbul.[2]
