Small helicopters play tennis

Hanover (Agencies) - helicopters entered the mechanism that does not exceed 1.5 meters in length new application areas. During the flight in the air reveal helicopter for example, faults in solar energy systems generating electricity quickly by Camera thermal vehicle on them, according to the German news «DW», it has become easy to monitor bridges and turbines wind is used to generate electricity, as they are photographed precision air Pkamiradtha television also enable police to monitor the events taking place on the ground.Using these aircraft flying in the air drone scientists were able to detect the presence of penguins in Antarctica. The in Switzerland Vistamlha the farmers in the pre-harvest to track the presence of small antelope or partridge birds in their farms and save them before they kill them agricultural harvesting machines. There are these small helicopters mechanism different versions ranging in length from half a meter to a meter and a half, depending on the purpose of use.
Not only the talents of small aircraft to take pictures of excellent clarity of the air, but some types can also play tennis. The researchers have developed at the Institute of Zurich Technical robots small cyclase transmitted by air automatically without the need for GPS satellite GPS and without the need for a remote-controlled, but it is able to navigate autonomously and to act as it should, even in confined areas and enclosed, with the help of a small computer built in it.During the exhibition the German city of Hanover, the researchers and students of the University of Zurich possible areas of application for the small helicopter, if the two play tennis together. Each plane is equipped robot arm or a bat to play. The aircraft hit the ball arm rotates back and forth. They also are equipped with cameras that senses a ball sites. And in each computer calculates the trajectory of the ball mathematically, and also calculates the momentum that tennis needs to move backward and forward to push the ball in the opposite direction.

All of this requires high precision and accurate calculations and knowledge of the science of automatic control, says student Fabian Muller, 26-year-old, who recently completed a master's thesis at the University of Zurich on the subject of robots plane, he says, «the real challenge is to maintain the stability of the robots in flight in the air and through the development of computer algorithms control Bhrkiha, so that the robot plane of what we want to do, and it also includes a flight on certain routes and doing acrobatic movements and then landing safely in the end.
