Scientists in biology and engineering at the University of Standardford of America have invented a unique robot, consisting of plastic materials, electronic connections and real bath feathers, called "PigeonBot" or "pigeon robot", simulating in his flight the birds whisk with their wings, and barely It can be distinguished from the flying pigeon.
Just looking closely, you can see the fan pulling the flying object forward, in a glide flight that looks like a bathroom sliding over the air.
With his PhD in engineering, David Leithnik was able to integrate real bath feathers into the device and even equip his wings with remote-controlled joints. Two scientific reports on the device have been published in two scientific periodicals, "Science Robotics" and "Science".
Initially, the team worked to examine the dead pigeons' wings, and then tried to reassemble forty feathers as much as possible into the device, due to the special flexibility of the feathers of birds.
Using their computer modeling, scientists found that only two angles of the joints can explain 97% of the wing's general shape, called the wrist and finger joint, to which the outer wing feathers are attached. The bathroom does not control each feather separately, but the movement of the feathers is linked mechanically to each other. In the BeijingBot robot, flexible strips between embryos took over.
In addition to a structure made of rigid foam boards, there are some electronics on the Beginbot on board such as a GPS navigation unit, a remote control, a motor with a fan, and joints actuators. The Dove Robot has great flexibility, light weight and fluid flow that do not disturb or damage the environment.
