Servo Motor motorek rotary e ku dikare hêmana mekanîkî kontrol bike ka meriv çawa di pergala servo de dixebite. This motor that allows for a precise control in terms of angular position, acceleration and velocity, capabilities that a regular motor does not have.

Amplifikator dikare voltaja an hêza nîşana inputê amûr bike. Ew ji tub an transistor pêk tê, veguherînek hêz û hêmanên elektrîkî yên din.

The circuit board can make the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuit and the optimization of the electrical layout. Lination Lijneya Circuit jî dikare were gotin (Desteya Circuit Printed) PCB û (Lijneya Circuit ya Zexmî) FPC. There are some good characteristics, such as high linear density, light-weight, thin thickness and good bending and so on.
