Design and implementation of four-legged container robotoverall circuit designAbstractChina is faced with an aging population,now more and more serious and the status quo,as humans age,the body will gradually retreat,but people are social animals,and is boundto have liquidity,then carry luggage items are likely to be older or less robust of the largerobstacles,therefore,a smart and convenient handling robots in People's Daily life scene isparticularly valuable in application,and has high development prospects.The volume of the four-legged luggage box we designed is similar to the size of anormal suitcase.It can adapt to all kinds of complicated terrains through four-leggedcrawling.No matter it is flat ground,ladder or depression,it can avoid obstacles throughultrasonic waves,which greatly guarantees the traveling stability.Second,it can also followthe user intelligently through color recognition,so that it can follow the user easily even incrowded airports.Finally,the start and stop of the container is very simple,and the mobileAPP can be used to control whether the container is started or not,which is very convenientand efficient.This time,we chose raspberry pie as the implementation basis of the containermodel.In this paper,the circuit analysis and design of the hardware part will be carried outaccording to the functions of the four-legged loading box,including the schematic diagramanalysis of the circuit design of raspberry PI and its extension board.Meanwhile,the motionsimulation of the PROE model of the four-legged loading box will be discussed.Keyword:Circuit design;Schematic diagram;Raspberry pie;PROE simulation;
