For consumers, the first requirement for purchasing a sweeping robot is that the sweep is swept clean. The sweep is mainly determined by the design of the sweeping system and the power of the suction fan. The most powerful guarantee for sweeping efficiency is sweeping the floor. The robot has a very intelligent path planning algorithm. Common sweeping robot algorithms are roughly divided into two types: random cover method and path plan type sweep.
Random coverage
Random cover method, also known as random collision navigation, but this does not mean that the robot really collides with objects in the environment, nor does it move randomly on the floor without any rules, in other words, "random" in engineering operations is also a It is difficult to meet the requirement. The random cover method means that the robot tentatively covers the work area according to a certain movement algorithm, such as a triangle and a pentagon track. If an obstacle is encountered, the corresponding steering function is executed. This method is a low-cost strategy of changing space by time, such as 100% coverage without time.
From the market feedback point of view, the random sweeping robot gives people the feeling that they are running around in the room, often unable to clean the room in full coverage, often appearing in a certain place repeatedly sweeping, sweeping, and no charge back. It is also entirely by luck. The random coverage method does not need to locate, nor has an environment map, nor can it plan the path. Therefore, its moving path basically depends on the built-in algorithm. The quality of the algorithm also determines the quality and efficiency of the cleaning. Common random sweeping robot systems internally preset a variety of cleaning modes to randomly switch the cleaning mode according to a certain algorithm, and the cleaning effect is completely built up by the cleaning time.
The robots with random cleaning algorithm are more representative of the iRobot Roomba 3-8 series, the average price is also more than 4,000 yuan, still relatively expensive.

Ethernet cables connect devices such as PCs, routers, and switches within a local area network.Most technicians refer to these standards as CAT5 and CAT6, respectively. Also CAT3 available. Because of this, many online stores that sell network cables use this abbreviated language as well.
The connector can by shield or non-shield type, raw cable can be UTP, STP, FTP type. Also the molded shape can be custom mould by straight, right-angle, 105 degree, etc.
These physical cables are limited by length and durability. If a network cable is too long or of poor quality, it won't carry a good network signal. These limits are one reason there are different types of Ethernet cables that are optimized to perform certain tasks in specific situations.
