Léo's head

Léo is a home companion robot in development. This page shows the current head (version 17) in a finish study: hood and face in bead-blasted, clear-anodised aluminium, a matte charcoal lower shell, and a minimal face where only the eyes, brows and lips show.

Animated sequence (24 s): he notices you, says hello, listens, is surprised and smiles.

Close-up of the left eye: white globe and lids, blue-lit pupil, aluminium face — The left eye: white globe and lids, 9 mm pupil lit blue from behind.
