Air food-passing robot and food-passing method thereof

An Air food-passing robot comprises two transmission wheels arranged in a transmission track. One end of each transmission wheel is connected with a servo motor, and the other end is connected with a connecting rod through a servo motor rotation shaft. The connecting rods are in circuit connection with a microcontroller. A stepping motor rotation shaft is connected with a food-passing container through a lifting line. The food-passing method comprises the steps of: 1) a service plate containing food is put into the food-passing container, a table number is input, a digital tube displays the table number, and a liquid crystal displays the food name; 2) the microcontroller controls a stepping motor to work, and the stepping motor lifts the food-passing container; 3) the microcontroller controls the servo motors to work so as to drive the two wheels to move towards a target dining table; 4) after a magnetic field, a reed relay is closed, and when the value of a counter is equal to the table number, the two wheels arrives the part above the target dining table; 5) the stepping motor rotation shaft drives the food-passing container to decrease, and a food taking port is closed of the food is taken out; and 6) the food-passing container rises to the original height again, and servo motors return to the original positions. The food-passing robot is safe, highly-efficient, convenient to operate and intelligent.

Computer robot crawling task distribution method and device, and computer robot data crawling method and device

The embodiment of the invention discloses a computer robot crawling task distribution method and device, and a computer robot data crawling method and device. The computer robot data crawling method comprises the following steps: a crawled historical page is stored into historical crawling data, whether a historical page corresponding to the URL(Uniform Resource Locator) cluster of a crawling task is in the presence in the historical crawling data or not is judged when the crawling task is in the presence, first target page data can be directly extracted from an available historical page if the historical page is in the presence and the existing historical page is available, the part of the historical page does not need to be repeatedly crawled, and system resources are saved. Meanwhile, the network bandwidth usage rates of all computer robots are detected in fixed time, the mean value E(w) and the variance D(w) of the network bandwidth usage rate of each computer robot are calculated and stored, and then, the availability of each computer robot is calculated according to E(w) and D(w). For the available computer robots, the computer robot for executing tasks is selected according to the descending order of an availability probability so as to reasonably distribute computer robot resources.
