Link : English Central “Ultralight Bionic Butterflies”
The video I´ve watched is about a German Company that
developed bionic butterflies that are just like the real ones because they can
fly and very close to each other. Their weight is of 1 ounce and height of around
20 inches. The most interesting part is that these robot animals are compound
of 2 motors, 2 batteries, infrared markers, and a pair of wings made up of soft
elastic material. These butterflies can really fly in a room surrounded by 10
cameras, infrared tracking and a central computer which coordinate their
movements. They are not for sale but this invention definitely shows continued research
efforts in technology.

The article that I´ve read was about a video that was taken in 2011 in Costa Rica. This video also was uploaded to the red recently. The video shows the perfect moment when a man in the jungle fed a crocodile by his own. In that places are very common to use these animals to give entertainment to other local people or visitors. And another man who was traveling on a boat over the lake filmed the video of that incredible moment, while he was looking at the local wildlife.
