Multi rotor flight experience

The exhibit consists of a micro drone, an operating controller, and a real drone flight experience area. Combining the basic principles of flight, it leads visitors to complete the process of drone flight from cognition to practice.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Taking a quadcopter electric drone as an example, the layout of the four rotors is in an "X" shape, with adjacent rotors turning in opposite directions. When the lift generated by the two pairs of rotors turning in opposite directions is equal, the effect of the reverse torque is just offset, thereby preventing the drone from spinning. By controlling the rotational speed of two pairs of rotors, various motion postures of the drone can be controlled. Drones have 6 degrees of freedom, including forward and backward, up and down, left and right movement, roll, pitch, and yaw rotation. However, the control channels only include the thrust channel, roll control channel, pitch control channel, and yaw control channel. Therefore, drones are a nonlinear system with strong underactuated coupling.
