September 02, 2016Do you miss the gyro toys we love playing when we are young? Now this toy idea have changed to large new world with plenty of great inventions like the unmanned aerial vehicles. The gyroscope shares a variety of categories and it could be divided to sensing gyroscope and indicating gyroscope from its function. The sensing gyroscope is mainly applied to the flying automatic control system for movement control of flying objects while the indicating gyroscope is mainly used in driving and pilot meter to indicate directions. Follows please enjoy two videos, you could get more different about gyroscope from the videos. Tim Peake demonstrates gyroscope - BBC News
