无人船方向的改变可以通过舵机进行控制，舵机的构成主要包括马达、变速齿轮

The change of the direction of the unmanned boat can be controlled by the steering gear. The composition of the steering gear mainly includes a motor, a variable speed gear mechanism, an internal circuit board, a steering gear casing and a position detector. The drive control center inputs the PWM signal to the internal circuit board of the servo, the chip on the circuit board decodes the input PWM signal, and then drives the motor to work, and outputs the corresponding torque and speed through the speed change gear, thereby driving the servo to run. At the same time, the position detector negatively feeds back the position signal of the steering gear to judge whether it has run to a predetermined position.

The change of the direction of the unmanned ship can be controlled by the rudder, which consists mainly of the motor, the variable gear mechanism, the internal circuit board, the rudder housing and the position detector. The drive control center inputs the PWM signal into the rudder's internal circuit board, the chip on the board decodes the input PWM signal, then drives the motor to work and outputs the corresponding torque and speed through the variable speed gear, thus driving the rudder to run, while the position detector negatively feedbackthe the rudder position signal to determine whether it is running to a predetermined position.

The change of the direction of the unmanned vessel can be controlled by the steering gear, which mainly consists of motor, variable speed gear mechanism, internal circuit board, steering gear shell and position detector. The drive control center inputs the PWM signal to the internal circuit board of the steering gear. The chip on the circuit board decodes and processes the input PWM signal, then drives the motor to work, and outputs the corresponding torque and speed through the variable speed gear, so as to drive the steering gear to operate. At the same time, the position detector feeds back the position signal of the steering gear negatively to determine whether it operates to the predetermined position.
