Wren
Flies the tower in six minutes. Reads the bolt numbers.
Wren is a folding quad that flies a scripted orbit around each tower: every insulator string, every cross-arm, every bolt. It packs into a 40 cm case and flies from the truck in 90 seconds.

Overview
Flies the tower in six minutes. Reads the bolt numbers.
A tower in six minutes
Wren flies the same orbit around every tower, so every photo lines up with last year’s. The 30x zoom reads the stamp on a bolt from 20 metres, well outside the safe approach distance.
Built for the cab
Arms fold, props fold and the whole kit fits behind the seat of a crew truck. Crews fly it on the way to a job rather than as a separate programme.
