What is "footbonaut"

The Footbonaut is a football training machine which fires balls at different speeds and trajectories at players, who must control and pass the ball into a highlighted square. Footbonaut was invented by Christian Güttler in Berlin, Germany. The machine is also described as a robotic cage. Mario Götze's winning goal of the 2014 FIFA World Cup Final has been credited to his years of practice using Footbonaut. The Footbonaut is also credited for the success of Borussia Dortmund, who first used the machine. There are several undisclosed clubs in Germany currently using Footbonaut in their trainings.
