Servo Introduction
The steering gear is also called servo motor which is originally used in ships, since it can control the angle
continuously through the program, so it has been widely used in intelligent steering robot to achieve all
kinds of joint movement, the characteristics steering gear are small volume, large torque, high stability,
simple external mechanical design. Either in hardware or software design, the design of steering engine is an
important part of car controlling, the steering gear is mainly composed of the following parts in general,
steering wheels, gear group, position feedback potentiometer, DC motor and control circuit. Figure 11-1 and
Figure 11-2 show the internal structure of the Servo. The Motor Driver Board uses a 180 degree SG90 (180
