A robot is a mechanical device that automatically performs work. It can accept human orders, run pre-programmed programs and act according to the principles formulated by artificial intelligence technology. Its task is to assist or replace human work, such as production, construction or dangerous work. Now, the international concept of robot has gradually approached the same. Generally speaking, people can accept that robots are machines that realize various functions by their own power and control ability. The United Nations Organization for Standardization adopted the definition of robot given by the American Robotics Association: "Programmable multifunctional manipulator for handling materials, parts and tools; Or a specialized system with variable and programmable actions to perform different tasks (above from Baidu Encyclopedia)

Electric toys can only be remotely controlled by humans at most. Generally speaking, it is impossible to realize programming self-control or work according to the pre-specified principles.

To sum up, the difference between robots and electric toys lies in:

1, mission purpose: The mission purpose of the robot is to complete a series of tasks for industrial production and scientific investigation; Electric toys are only used for entertainment.

2. Behavior mode: The robot can be remotely controlled by human beings, or pre-programmed, or work according to pre-specified principles; Electric toys can only be remotely controlled by humans, and a few high-end toys can be simply programmed (just simple programming, which is different from the complexity of industrial robot programs).

3. Price: Needless to say. . . To some extent, the CNC machining center of mechanical finishing can be regarded as a robot, and its price is not affordable for ordinary enterprises, let alone individuals; Toys are usually cheap.
