Robotic bird

Abstract

A robotic bird, comprising - a body, extending along a longitudinal axis between a head and a tail, - two fixed wings, connected to the body on opposite sides of the body, wherein each wing has a vertical cross-sectional shape along the longitudinal axis of the body, which gradually transforms in a direction away from the body, from a first shape which is convex at an upper side and concave at a lower side to a second shape which is convex at an upper side and convex at a lower side
