Researchers Build Bee Robot That Can Twist
With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype can fly stably in all directions.

Bee++, a robotic bee developed by researchers at Washington State University (WSU), can fly in all directions with stability and achieve the six degrees of free movement exhibited by most flying insects.
The prototype features four wings comprised of carbon fiber and mylar and four lightweight actuators to control them.
Notably, Bee++ can perform the complex yaw (twisting) motion, which allows a robot to focus on a point, maintain control, and avoid a crash.
The researchers accomplished this by designing the wings to flap in an angled plane and increasing the speed of wing flapping from 100 to 160 times per second.
Having all six degrees of movement also allows the robot to make evasive maneuvers and track objects.
