Seal, in fact, as long as the implementation of electronic seal, just like electronic contract, after popularization, the robot can only be changed into other functions

Stamping is not just as simple as putting the seal on paper... Have you ever thought that the action of stamping will bring some responsibilities, or that stamping has been made a loophole to illegally use the stamping machine.

Very complete

Service Location: Self-search gives people the impression that there can be many scenes, but is it not realistic to appear in the whole campus? It may be the arrangement of the main teaching building and a little speculation
Number: unknown, whether there may be a large number of queues at some time, maybe more students and teachers will directly look for the placement point of the robot in standby state, then is it better to make a fixed one? It doesn't have to be a robot. If a fixed machine that integrates these functions appears, it is also excellent, a little guess.
I would like to ask the author if he is not worried about being misappropriated when this kind of service case is sent out, or if he is a little curious

Is a good design
