What are the three characteristics of a machine?

(1) has the function of perception, that is, the function of obtaining information. Robots can obtain information about the external environment, such as sound, light, object temperature and so on, through the "perception" system.

(2) It has the thinking function, that is, the function of processing information. Robots think through the "brain" system, and their thinking process is the process of processing, processing and making decisions on all kinds of information.

(3) It has the action function, that is, the function of outputting information. Robots use "executive" systems (actuators) to complete tasks, such as walking and making sounds.

Let's understand the composition of the machine:

1. power part: it is the source of machine energy, and it converts all kinds of energy into machine energy (also called mechanical energy).

2. Work part: the part that directly realizes the specific function of the machine and completes the production task.

3. Transmission part: an intermediate device that transmits, converts or distributes the motion and power of the power part to the working part according to the working requirements.

4. Control part: the part that controls the machine to start, stop and change the motion parameters.
