AI Technical Summary

Problems solved by technology

Its disadvantages are: large universal wheels and pedals take up a lot of space, and when people ride a bicycle, their legs need to alternately move up and down, which also requires a certain amount of space, and riding a bicycle itself also requires physical strength

In addition, both of the above-mentioned carts fail to make full use of the existing shopping carts in the supermarket, thereby increasing unnecessary costs

There are also electric vehicles used in foreign supermarkets, but their structure is relatively bulky, the production cost is high, and the loading space is small, so they cannot be popularized.
