We use navigation and intelligent avoidance algorithms to plan the path of the automatic robot. When AR encounters a new unrecognizable terrain, it will give control to the customer who can control the AR on its mobile app and navigate to the specified destination. We have initially designed an autonomous delivery robot with the cost of 2774 dollars.展开更多

Methods: We randomly collected a total of 4450 samples of 7 different types of takeaway meals, which were the most consumed by local residents from takeaway platforms. The main ingredients, auxiliary ingredients, as well as the weight used in takeaway meals were collected. The sodium content in takeaway meals was obtained by calculation. Results: Obtained results show that the sodium content in three large China cities is alarmingly high. Comparing medians (interquartile range) of takeaway meals from different cities, Beijing contained the highest sodium content per portion (1371.3 mg (890.3 - 2137.4)), followed by Hangzhou (1348.45 mg (694.25 - 1541.62)) and Shanghai (340.1 (259.75 - 942.25)). In addition, the sodium content between pasta and porridge, Chinese meals, and western meals show significant differences (p 0.05). Compared with Chinese Dietary Reference Intakes, the average sodium content exceeded dietary recommendations for one takeaway meal. The sodium content differed among takeaway meals prepared with various cooking methods and meats. Conclusion: Notable differences are detected in takeaway meals’ sodium content between several large cities in China. To meet China’s target salt intake, consumers in these cities are highly recommended to reduce sodium content in their everyday meals.展开更多
